Heritability has long been known to play a role in aortic aneurysm and dissection for individuals with the Marfan and Loeys-Dietz syndromes. Recent research at Penn Medicine and elsewhere has revealed the presence of genetic variants linked to these syndromes in non-syndromic disease. In this podcast, clinical genetics specialist Staci Kallish, DO, discusses this phenomenon, reviews ongoing studies to determine the risk for aortic aneurysm and dissection in the general population, and the protocols for candidates for genetic evaluation and testing in at- risk populations.
Dr. Richard Haier is an emeritus professor of Pediatric Neurology at UC Irvine, who spent his career studying the neuroscience of intelligence. Over the course of his career, Haier has come to believe in the existence of a “g-factor,” a measurable quantity of broad spectrum intelligence that is universally predictive of success in all cultures. He also believes that intelligence is a fixed characteristic, and that it's possible to predict someone's intelligence by watching how their brain works when trying to solve a puzzle. We sit down with him to figure out how far one can take this theory of intelligence before running headlong into a heartless social darwinism, why intelligence research feels so creepy, if IQ tests are actually measuring what we think they're measuring, if intelligence is really the thing that we should be optimizing for, and if it's possible for technology to make us dumber.

IQ is, to say the least, a fraught concept. Psychologists have studied IQ—or g for “general cognitive ability”—maybe more than any other psychological construct. And they've learned some interesting things about it. That it's remarkably stable over the lifespan. That it really is general: people who ace one test of intellectual ability tend to ace others. And that IQs have risen markedly over the last century. At the same time, IQ seems to be met with increasing squeamishness, if not outright disdain, in many circles. It's often seen as crude, misguided, reductive—maybe a whole lot worse. There's no question, after all, that IQ has been misused—that it still gets misused—for all kinds of racist, classist, colonialist purposes. As if this wasn't all thorny enough, the study of IQ is also intimately bound up with the study of genetics. It's right there in the roiling center of debates about how genes and environment make us who we are. So, yeah, what to make of all this? How should we be thinking about IQ? My guest today is Dr. Eric Turkheimer. Eric is Professor of Psychology at the University of Virginia. He has studied intelligence and many other complex human traits for decades, and he's a major figure in the field of “behavior genetics.” Eric also has a new book out this fall—which I highly recommend—titled Understanding the Nature-Nurture Debate. In a field that has sometimes been accused of rampant optimism, Eric is—as you'll hear—a bit more measured. In this conversation, Eric and I focus on intelligence and its putatively genetic basis. We talk about why Eric doubts that we are anywhere close to an account of the biology of IQ. We discuss what makes intelligence such a formidable construct in psychology and why essentialist understandings of it are so intuitive. We talk about Francis Galton and the long shadow he's cast on the study of human behavior. We discuss the classic era of Twin Studies—an era in which researchers started to derive quantitative estimates of the heritability of complex traits. We talk about how the main takeaway from that era was that genes are quite important indeed, and about how more genetic techniques suggest that takeaway may have been a bit simplistic. Along the way, Eric and I touch on spelling ability, child prodigies, the chemical composition of money, the shared quirks of twins reared apart, the Flynn Effect, the Reverse Flynn Effect, birth order, the genetics of height, the problem of missing heritability, whether we should still be using IQ scores, and the role of behavior genetics in the broader social sciences. Alright folks, lots in here—let's just get to it. On to my conversation with Dr. Eric Turkheimer. Enjoy! A transcript of this episode will be available soon. Notes and links 3:30 – The 1994 book The Bell Curve, by Richard Herrnstein a Charles Murray, dealt largely with the putative social implications of IQ research. It was extremely controversial and widely discussed. For an overview of the book and controversy, see the Wikipedia article here. 6:00 – For discussion of the “all parents are environmentalists…” quip, see here. 12:00 – The notion of “multiple intelligences” was popularized by the psychologist Howard Gardner—see here for an overview. See here for an attempt to test the claims of the “multiple intelligences” framework using some of the methods of traditional IQ research. For work on EQ (or Emotional Intelligence) see here. 19:00 – Dr. Turkheimer has also laid out his spelling test analogy in a Substack post. 22:30 – Dr. Turkheimer's 1998 paper, “Heritability and Biological Explanation.” 24:30 – For an in-passing treatment of the processing efficiency idea, see p. 195 of Daniel Nettle's book Personality. See also Richard Haier's book, The Neuroscience of Intelligence. 26:00 – The original study on the relationship between pupil size and intelligence. A more recent study that fails to replicate those findings. 31:00 – For an argument that child prodigies constitute an argument for “nature,” see here. For a memorable narrative account of one child prodigy, see here. 32:00 – A meta-analysis of the Flynn effect. We have previously discussed the Flynn Effect in an episode with Michael Muthukrishna. 37:00 – James Flynn's book, What is Intelligence? On the reversal of the Flynn Effect, see here. 40:00 – The phrase “nature-nurture” originally comes from Shakespeare and was picked up by Francis Galton. In The Tempest, Prospero describes Caliban as “a born devil on whose nature/ Nurture can never stick.” 41:00 – For a biography of Galton, see here. For an article-length account of Galton's role in the birth of eugenics, see here. 50:00 – For an account of R.A. Fisher's 1918 paper and its continuing influence, see here. 55:00 – See Dr. Turkheimer's paper on the “nonshared environment”—E in the ACE model. 57:00 – A study coming out of the Minnesota Study of Twins reared apart. A New York Times article recounting some of the interesting anecdata in the Minnesota Study. 1:00:00 – See Dr. Turkheimer's 2000 paper on the “three laws of behavior genetics.” Note that this is not, in fact, Dr. Turkheimer's most cited paper (though it is very well cited). 1:03:00 – For another view of the state of behavior genetics in the postgenomic era, see here. 1:11:00 – For Dr. Turkheimer's work on poverty, heritability, and IQ, see here. 1:13:00 – A recent large-scale analysis of birth order effects on personality. 1:16:00 – For Dr. Turkheimer's take on the missing heritability problem, see here and here. 1:19:00 – A recent study on the missing heritability problem in the case of height. 1:30:00 – On the dark side of IQ, see Chapter 9 of Dr. Turkheimer's book.

Dr. Stephen Storage, a child psychiatrist, discusses the key stages of child psychological development and the impact of family dynamics and early childhood experiences on a child's mental health. He explains that there are four stages of development: infancy (0-2 years), early childhood (2-6 years), middle childhood (6-12 years), and adolescence (12-18 years). Each stage has a developmental task that the child must master, and if they don't, it can lead to issues later in life. Factors such as attachment, trauma, and adverse childhood experiences can shape a child's psyche and impact their relationships and mental health as adults. Trauma shapes the biology of the developing brain, leading to changes in brain activity and blood flow. The impact of trauma on the brain can be addressed through various therapies, supplements, and lifestyle changes. Genetics play a significant role in mental health conditions, with conditions like ADHD and autism having a high heritability. The three pillars of brain health are sleep, exercise, and nutrition. Social media can have negative effects on the developing brain, leading to higher rates of anxiety, depression, and ADHD. However, social media can also be a platform for connection and spreading awareness about mental health. It is important to set limits on social media use and ensure that the content is interactive and educational. Play is crucial for the psychological development of children, promoting problem-solving, creativity, social skills, emotional regulation, and confidence. Parents should be aware of the signs of mental health struggles in their children and foster open communication.Amen Clinic@drstevenstorage@therunningwinemom_

De sociale medier TikTok, Facebook og Instagram flyder over med videoer, hvori det påstås, at simple fingerøvelser kan gøre din hjerne skarpere. Måske er du selv stødt ind i øvelsen, hvor du skiftevis skal lave en pistol og et peace-tegn med højre og venstre hånd? Det er Brainstorm-værten Nana i hvert fald, og hun har sat sig for at komme til bunds i, om videoernes postulater har noget på sig. Kan ‘fingergymnastik' virkelig styrke kognitionen? Både Nana og Anne Sophie er lidt skeptiske over for ideen, men ifølge to hjerneforskere - Kamilla Miskowiak og Albert Gjedde - er effekten af fingergymnastik på vores hjerner noget mere nuanceret end som så… Svaret på, om fingergymnastik kan gøre hjernen skarpere, tager os forbi kinesisk naturmedicin, forbi musikeres hjerner og forbi memoreringsteknikker, der involverer bøf bearnaise og bilnummerplader.

Listen to ASCO's Journal of Clinical Oncology essay, “The Heritability of Cancer” by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada. The essay is followed by an interview with Granek and host Dr. Lidia Schapira. Granek shares how her mother's diagnose with breast cancer continues to shape her own life and experiences. TRANSCRIPT Narrator: The Heritability of Cancer, by Leeat Granek I was 9 years old when my mother was first diagnosed with breast cancer and 25 when she died. The boundary between before and after is so clear that it feels like I have lived two lives. I went from being a careless, cerebral, quirky child to a rough version of the responsible, reliable, and vigilant adult I would eventually became. With cancer came the fear of losing my mother, and with that fear came an unwelcome but necessary maturity. There were other important life events impacting our family around that time that contributed to this sense of split. We had just moved from Israel to Toronto and knew few people in our new environment. My mother had just given birth to my baby brother, and my parents had bought a new house for our growing family. At the time, I was starting third grade in a new school—the fifth new school since beginning kindergarten. All this in addition to the diagnosis. My mother was only 33 years old—the same age I am now. While I adapted to everything else—new house, new school, new brother, new country—cancer insisted on sticking around, and it claimed not only my mother's life but, in many ways, my own. Cancer enters the body of the caregivers in ways that move far beyond the domestic work involved in the running of the house or the management of medications and appointments. It can become part of caregiver DNA through inherited genes, but it often does so in more insidious ways. My mother lived with the disease for 17 years before she died in 2005. It is fair to say I grew up in the hospital. Over the years, there were multiple surgeries, along with episodes of weekly chemotherapy and daily radiation sessions. She suffered a host of complications that came with metastatic disease and its treatment, including four instances of strep A bacteremia. Many major events happened in the hospital. We ate Chinese food with our matzos on Passover in her room and lit Hanukkah candles in the waiting room where we accidentally set off the fire alarm on the seventh night, to the consternation of the nursing staff. My 11th, 15th, 18th, and 25th birthdays were celebrated in cramped hospital quarters, cutting the birthday cake with a dull plastic knife. Indeed, the last birthday we had together was my 25th, and we marked it in the hospital 2 days before she died. In her last lucid moment, she managed to miraculously lift out of the fog caused by brain metastases to give me a kiss and exclaim “Mazal tov, Leeatie!” I remember the sounds and the smells. Static codes being called out over the hospital loudspeakers. The haunting “clink, clink, clink” of the staples being removed from my mother's skin graft and landing with a loud clatter in a silver bowl. The pale green hallways and their antiseptic smell, which I grew to hate. The airless temperature that was neither hot nor cold—hospital weather, I used to call it. The hospital, with its sounds and smells, was my second home. It sounds awful. And it was a lot of the time, but there were many good moments as well. My mother was smart, intuitive, funny, and astonishingly optimistic. She was always laughing and incredibly giving with her love and affection. We were exceptionally close. Her eyes lit up and her arms stretched out to give me a hug every single time I walked into her room. She would say things like, “Leeatie, I love you so much. I wouldn't change a single thing about you! How did I get to be so lucky to have a daughter like you?” and “There's no one in the world I would rather spend time with than you.” I didn't have to do anything to earn her affection. I felt that I always came first, that I was always wanted and loved, and that my mother was always entirely there for me in every sense of the word. The hospital days that punctuated much of my childhood, adolescence, and young adulthood were both an annoyance and a blessing. There was nothing else to do but simply be together, which was fun and easy, thankfully. When I was older and no longer living at home, I would sometimes sleep over in her hospital room during her admissions. We would curl up in the twin bed and talk for hours until we both fell asleep, or we would sit together, each absorbed in her own book, comforted by the warmness of being together. When I think about being a caregiver for my mom, and by extension a caregiver for our family, it was not the hours of care work—the babysitting, driving to appointments, spending time in the hospital—that consumed me. The impact was long-lasting and continues to this day. As a health psychologist and a researcher in the area of psychooncology, I know the permanent and long-term devastations cancer causes throughout the caregiver's—in my case, the daughter's—entire life span. To this day, I have no real sense of what normal physical development for a woman should feel and look like, and in some sense, I never will. I entered puberty around the same time my mother was having her breasts and ovaries removed, which made that phase frightening and emotionally difficult. And now, I have no mother to turn to and ask about my endlessly evolving female form, no mother to guide me through future pregnancies or talk me through gray hair and menopause. Cancer shaped my young adulthood and my emotional development. At 20 years old, I was dealing with issues facing 60-year-olds who care for ill and aging parents. Because part of me recognized that time was running out—indeed, because I lived almost my entire life with a neon awareness of my mother's mortality—I was tethered to home and making decisions about school, life, and love that would keep me close to her. I don't regret these choices or a single moment that I chose to spend with her, and now I have an entire lifetime to come and go as I please. Being challenged with a cancer-driven perspective at 20, however, carries risks of having an entire lifetime being developmentally out of step with one's peers and unprepared for life events outside a hospital. For example, at 25, I could look death in the face without trembling and without abandoning my mother at her end, but I was unprepared to face the dating world that most young adults would have no trouble navigating. Although I was and remain a loved, nurtured, and supported daughter, cancer diverted the vast majority of the temporal, emotional, financial, and physical resources in our family toward fighting the disease. When she was alive, my mother was fully present in my life. But even her unconditional love could not repair the reality of my out-of-sync development as a child and young adult or today make up for her continued absence in my life. My absent mother is at the core of a black hole of grief that remains inside of me and that has been painfully pried open with subsequent losses to cancer—my grandmother and my aunt, a professor I admired and family friend that I loved. Each loss re-exposes a haunting grief I have learned to accept and live with. Grief is a shadow that looms large in my life. It is both the topic I chose to study and the affect I advocate fiercely for,1–4 because as I have learned through my own experiences and research, love and light come from the same place as grief and darkness. The ability to grieve our losses fully also allows us to love and appreciate the people in our lives when they are still with us. And then, of course, there is the worry: the biannual check-ups, magnetic resonance imaging scans, and mammograms; the surveillance and the false positives and the constant paradoxical tension that comes with the awareness of the nature of these tests provide a false sense of control over a disease that refuses to be harnessed. The literature about the impact of parental cancer on children at the time of diagnosis, during treatment, after surgery, and even at the time of death is extensive,5–6 but few of these studies acknowledge how much this disease alters the life course of the child well after the parent has recovered or has died. Being a caregiver for a patient with cancer consumed much of my childhood, adolescence, and young adulthood when my mother was alive and charted the course for my future as a health psychologist working in the field of psychooncology. Although many years have passed and although I have a doctorate in hand, several years of postdoctoral training in the field of psychooncology, an academic career studying these issues, and dozens of publications from my research on the psychological and emotional effects of cancer on patients, caregivers, and their families,7–16 from time to time, I still feel like a scared 9-year-old child trying to gain control over this disease and get out of the shadow that cancer has cast on my life. Dr. Lidia Schapira: Hello, and welcome to JCO's Cancer Stories, the Art of Oncology, which features essays and personal reflections from authors exploring their experience in the field of oncology. I'm your host, Dr. Lidia Schapira. I'm a Professor of Medicine at Stanford University. Today we are joined by Dr. Leeat Granek, Associate Professor at York University in Toronto, Canada, in the School of Social Policy and Health Management. In this episode, we will be talking about her Art of Oncology article, "The Heritability of Cancer." At the time of this recording, our guest has no disclosures. Leeat, welcome to our podcast and thank you for joining us. Dr. Leeat Granek: Thank you so much for having me. It's a pleasure. Dr. Lidia Schapira: Your essay is a classic, and I'm so glad that we were able to include it in the recent anthology of Art of Oncology. So let's start by talking a little bit about what led you to not only write, but decide to share this essay eight years after your mother passed of breast cancer. Bring us to that moment. Tell us what you were thinking. Dr. Leeat Granek: Yeah, so that's a great question. And I recently, in preparation for this interview, reread it, and I was a little taken aback, even by how exposed and how vulnerable it was. But I really like that essay, and I'm really glad that it was published. It was kind of a culmination of a lot of thoughts that I was having as a person who has researched grief for many years, and as a person who was working in the field of psycho oncology, doing research in the area, and as a grieving daughter. And I think eight years is nothing in the grieving trajectory, right? We often think about grief as something acute that happens to you, and then you get over it and you move on with your life, and that certainly has not been my experience of grieving. I think it changes as you change, and it's just a constant presence in your life. And I was thinking about that in the context of being a caregiver for somebody who has cancer. So I think my experience is a little different than others, just because my mom was very young. She was 33 when she was diagnosed, and I was only nine. And she lived with this metastatic disease for nearly 20 years. So we had a very long journey with cancer. And I can kind of see now, as I reread it, the parallel thinking processes I had about grief and about cancer. And being a researcher in the field, I still feel that there are a lot of gaps in terms of the caregiver experience. But this idea of heritability, we often think about cancer as something you inherit genetically through our genetic makeup. But I think that it really, especially when you're young, changes your whole life trajectory. And I could not find anything in the literature that spoke about it in that very longitudinal kind of way and the way the impact of cancer changes you throughout your entire life. And so it just came from a very personal place, but also that intersection of being aware of the different literatures and how they came together. Dr. Lidia Schapira: Let's unpack this a little bit. One of the things that you just said was that you shared your vulnerabilities, and I want to ask you a little bit more about that. Here you are. You're about the same age that when your mother was living with this as a young woman. I think you said that she was diagnosed roughly at the time that you were writing this. And you decide to explore this wearing a little bit of your research hat in a very deeply personal way. But then the question I wanted to ask you is your decision to share this with the community of oncologists, the people you knew very well because they had looked after your mother for all those years. Tell me a little bit about that. How did you make the decision not only to write it, but to share it? Dr. Leeat Granek: That's a great question. This also pertains to the research that I do, because a lot of the research I was doing at the time, as a result of my experiences with cancer teams as a child, looked at the emotional impact of being an oncologist. I did a series of studies looking at the way oncologists grieve and how they feel when patients die, some of the emotional burdens of the work. And they were very vulnerable in sharing their experiences. And so I thought, well, they're telling me about their experiences, I can also tell them about mine. And I think that there's kind of a mythology around oncologists. I'm doing studies now on surgeons as well, and I think there's the same mythology around surgeons is that they don't feel or everything is compartmentalized and everything's separate. But from my research, I knew that that wasn't the case. And I felt that, although oncologists and oncology teams and nurses as well, witness patient suffering and family suffering, that there was nothing in the literature that kind of brought it home in this very visceral way. I don't think it would have been a surprise for any oncologist reading it, because when you follow families or when you follow parents, you see the children coming in. And so there was something about this intersection of their vulnerability and my vulnerability, enriching the experience of what it means to be a patient, and what does it mean to be a healthcare provider, which is not something that's often discussed in medicine at all. Dr. Lidia Schapira: So to your point, I think that telling the story was a beautiful sort of vehicle for opening up the topic. You were doing it through your research. But telling a story can often start a conversation in a very different way. That's what we try to do also in selecting these essays for Art of Oncology, to bring a story that's deeply personal, that reflects one's lived experience, but opens up a topic that is otherwise perhaps not talked about as much as we think it should. So let me go back and ask, what was the impact of telling the story on your research? Dr. Leeat Granek: I just want to add something about what you just said about stories. The very first paper that I published on oncologist experiences of grief, I wrote an op-ed for the New York Times about that research. And it was very story-based. It was very much telling a story, and I was telling my own story as well as a story about the research. And the response to that op-ed was so profound and so much more powerful than any paper I had ever published. I got thousands of emails from people around the world, oncologists and healthcare providers around the world, just saying how touched and how moved they were by that op-ed. And that is the power of the story that you're talking about right now, that we're vying for these peer-reviewed articles all the time. But actually, the impact of just telling a story is so much more meaningful and visceral for the reader than just outlining the research findings. Dr. Lidia Schapira: And it sounds like just receiving all of those emails after your op-ed was probably very validating. We can get rejected when we apply for grants, but people were telling you what you're onto is really significant. Dr. Leeat Granek: Yeah. And I think that validating in the sense that what I felt was that as you, exactly the words you just used, that it was a conversation that was not being had to the detriment of all. And so it validated that feeling of, yeah, this is something that's really important for us to be talking about in oncology. And just in terms of the response to "The Heritability of Cancer," it was a long time ago. This is 2014, so 10 years ago. I don't remember entirely what are the specific things that people said, but I do remember getting a lot of emails about it, mostly from healthcare providers, so less from caregivers or patients who may not have subscriptions to JCO, but maybe through the podcast now will have more access. Just saying this really shed some light as to the experience of what does it mean for the extended family that I think is not often considered. Certainly, we don't think about kids very often when a parent is going through cancer. Dr. Lidia Schapira: If you were to write this today, what would you do differently? Dr. Leeat Granek: I think what's changed for me– I don't think I would do anything differently, but what I think has changed is that I've had a child since I written that. Having a seven-year-old and thinking about what it's like to be going through a cancer diagnosis or cancer treatment while you have children. That piece was very centered on me and my experiences, and now I have even another layer of empathy and compassion for my mom, who had a newborn at the time. And I can just not imagine anything more– it's going to make me cry just even now just by thinking about it - it's just scary to have such a life-threatening diagnosis when you're a parent. Just like grief, like I said earlier, being a victim of cancer or being part of your family, that impact is lifelong and it changes as your development changes. Now as a parent, my grief is different than it was before I became a parent. And now as a parent, my understanding of what my mother was going through is changed. That terror and fear is so overwhelming. Dr. Lidia Schapira: So, Leeat, I can't help myself, but I need to ask you some practical questions. You're a psycho-oncologist, an expert in grief, and you've talked to and interviewed hundreds of oncologists who have shared stories, you're now a parent, you've lived through it. What it makes me think is that when we think about grief counseling or support for grieving children or bereaved spouses or parents, you think about it as an acute intervention and what you're suggesting is this needs to be explored throughout the life cycle. What are your thoughts about that and what should we be thinking about? Dr. Leeat Granek: I've written a lot about this in my grief work. The evidence for psychological counseling for grief is not strong actually when we look at the literature. For acute grief experiences in the immediate aftermath, sometimes it's helpful having someone to talk to. But in actuality, the most helpful is having a community in which grief is an open, accepted, acknowledged, part of living life. And that does not change after the first month or the first six months or the year, five years or ten years. Other people may have moved on very quickly, but you're left with the impact of that loss. And I think the impact of that loss is not only after, when the person has died, it's also that progressive loss of function. The kind of witnessing of your loved one deteriorating. It's not just meals that you need, you also need that emotional support. And that emotional support doesn't necessarily have to take the form of, “Tell me about your grieving right now.” Sometimes it's just being with. And I think that certainly in North America, we're not very good at integrating grief, loss, pain, suffering, and negative emotions into our day to day lives. So partly, 10 years, 20 years, or 25 years later, it's hard for people to remember that loss. So I think the person is grieving that many years after may have to reach out and ask for the support. But I think it's done really well in certain religions. I am Jewish and in the Jewish background, you have so many layers of mourning that's lifelong. So you have the acute grieving experience where it's seven days or 30 days or one year. And then every year progressively after that four times a year, you say a blessing and remembrance and give charity in the name of the dead. And for religious people, I'm not religious, this idea of every single day for that first year having to go synagogue and having to have at least nine other people that could be there with you to say the prayer for the dead, whether you believe or not believe, whether you're religious or not, I think the brilliance in those kinds of rituals is that it simply brings you together with other people who see you everyday. And decades later, still that four times a year that you're meeting with people and you're saying a prayer, or that yearly yahrzeit, that memorial allows people a very very defined space in which to support the mourner. And I think other religions have it too. Dr. Lidia Schapira: Those are beautiful thoughts, and I think it speaks to connection and community as a way of supporting rather than pathologizing the grief and thinking what one needs is some sort of a professional intervention. I can't help but add that as a community of caring oncologists, we are constantly grieving. We are immersed in grief, and in part, there is no label for how we feel. There is a small literature that you probably know far better than I do on disenfranchised grief, which is the idea that we can't quite claim to grieve because we weren't a relative or best friend, but we deeply cared and we lost and we grieve. So I find that this conversation is so helpful because I think what we're doing is we're talking about what we ought to be talking about more: perhaps acknowledging more from a point of view, as you say, of a parent, researcher, caregiver, medical or healthcare professional who's involved. We are living in a society where perhaps we are afraid to think that grief is a part of our life, and we can be happy even if we grieve. Dr. Leeat Granek: Yeah. Dr. Lidia Schapira: Happiness is not just the absence of sadness, I think, I don't know. You are the psycho-oncologist, tell me if I'm wrong. Dr. Leeat Granek: I so appreciate what you're saying and it makes me sad to hear that grief is still so stigmatized among oncologists. I think what my research has found and all my conversations with people over the decades now is, of course, oncologists feel a lot of things. Not just grief but pain and suffering, distress at seeing their patients and their families suffering and declining. Why wouldn't they? They are human beings. So I think this idea that people don't feel or don't have space to feel is part of what leads to burn out actually. I think there's a kind of fear that grief and the pain and suffering is the burn out but it's not. In fact, what's the burn out is the inability to talk about or to have a space to discuss it. And I also think that the thing that gives meaning to the work is that relationship with patients. And by the way, I'm finding that with the surgeons as well. The surgeons are even more kind of disconnected in terms of emotions. We kind of assume that they feel nothing, that they are so disconnected. By the way, I just have to say, the surgeons say, “I can't believe the oncologists does that job.” They find it really hard to believe that oncologists can do that, that they can never do that job. And the oncologists say that about the surgeons, too. So I think it's very interesting how different medical groups look at each other. But there's this kind of sense that's very unique about the grieving experience of how care providers is and they feel a lot of guilt and a lot of self doubt, and self criticism when patients die even though they know consciously that there's nothing that they could've done and that is just the disease that is taking over. That lack of control and that sense of having failed the patient is so strong. That is a very unique grieving experience for providers who feel responsible for the care of their patients. The fact that there is no training or no education or no space to talk about that is just appalling to me as a psychologist. Because I just think you learn how to do everything else. There's so much training on communicating bad news, on dealing with patient anger, on dealing with patient emotions and how to respond. But nothing on how to deal with your own emotions in response to this. For years, it's just about communications training. One of the things we find in the literature is that even when you provide communication training to oncologists that have to discuss end of life, often those skills are not sufficient to be able to have that conversation. And what's missing is the notion that I found in my own research that they don't have this conversation because they feel so uncomfortable with it themselves. And so until they have some self reflective practice for healthcare providers, all the skills training in the world is not going to help because it's about your own emotional resistance. Dr. Lidia Schapira: Well, this has been a phenomenal conversation, and I hope people will look at some of the beautiful research you've done in this field. Thank you so much for having shared your own experience, for the work you do, and for participating in today's podcast. Dr. Leeat Granek: Thank you so much. I really enjoyed it.

Famous schizophrenia researcher E. Fuller Torrey recently wrote a paper trying to cast doubt on whether schizophrenia is really genetic. His exact argument is complicated, but I feel like it sort of equivocates between “the studies showing that schizophrenia are genetic are wrong” and “the studies are right, but in a philosophical sense we shouldn't describe it as ‘mostly genetic'”. Awais Aftab makes a clearer version of the philosophical argument. He's not especially interested in debating the studies. But he says that even if the studies are right and schizophrenia is 80% heritable, we shouldn't call it a genetic disease. He says: Heritability is “biologically vacuous” (Matthews & Turkheimer, 2022), and I think we would be better off if more of us hesitated to assert that schizophrenia is a “genetic disorder” based predominantly on heritability estimates. I think about questions like these through the lens of avoiding isolated demands for rigor. There are always complicated ways that any statement is false. So the question is never whether a statement is perfectly true in every sense. It's what happens when we treat it fairly, using the same normal criteria we use for everything else. https://www.astralcodexten.com/p/its-fair-to-describe-schizophrenia
In this episode, my guest is Dr. Karen Parker, Ph.D., professor of psychiatry and director of the Social Neurosciences Research Program at Stanford University School of Medicine. We discuss the biology of social connections and bonding in babies, children and adults. Dr. Parker explains our current understanding of autism and autism spectrum disorders: what they are, why the incidence of autism has increased so dramatically in recent years and both the current and emerging treatments for autism. We also discuss the condition formerly called “Asperger's.” This episode is highly relevant for anyone interested in child and human development, how social bonds and communication form, and those curious about autism and other spectrum conditions.

Discussion of ADHD is EVERYWHERE in the news and social media. Often we hear patients, friends, and family members stating “I saw a post on FB/Instagram/Twitter/TikTok about ADHD that resonated with me, should I get tested?” While many people experience periods of inattention, unfocused motor activity, and impulsivity, those with ADHD experience these symptoms to a much greater degree, and these behaviors can often interfere with their social lives, working lives, and general mental health. Depending on your age and many other social factors, screening and evaluation for ADHD may have passed you over during your young, formative years. Thankfully, meaningful research exists to provide helpful data on how to diagnose and manage this condition!So let's learn more, shall we?

In this episode, my guest is Dr. David Linden, Ph.D., professor of neuroscience at Johns Hopkins University School of Medicine and the author of many popular books about the brain. We discuss individual differences between people — focusing on differences in how people sense the world around them and the roles that chance, heredity, and life experiences (even in utero) play in determining our physical and cognitive traits. We discuss the bidirectional connection between the mind and body and how our thoughts and mental practices (e.g., meditation and breathwork) impact our health. We also discuss the link between inflammation and depression. We also discuss Dr. Linden's terminal illness diagnosis, his mindset during chemotherapy and what his diagnosis has taught him about the mind, gratitude, time perception and life. This episode also covers sensual touch, cerebellar function, and epigenetic inheritance and ought to be of interest to all interested in neuroscience, genetics, psychology and human development.

Paul and David step away from the study of psychological universals to discuss the ways in which we are different from one another. What is our best theory of personality? How is personality assessed? Do personality tests predict behavior? What does it mean to be intelligent? Do IQ tests measure anything important? What sorts of things does IQ predict? Are there multiple intelligences? Finally we dip our toes into behavioral genetics. What is heritability? How heritable are psychological traits? Finally, can parents really shape the personality or IQ of their children?

Gavin Douglas and colleagues published a paper assessing microbiome research and assertions that the human microbiome explains missing heritability in nature. He discusses this issue and explains What are classic ways of understanding genetic variation in humans and how recently microbiome research has entered this understanding, What the holobiont model is and how it involves claims regarding the microbiome and missing heritability in nature, and How their paper views the microbiome as more of potential element in genetic variation in humans and necessitates more consideration regarding how to integrate it outside of the strict, holobiont model. Gavin Douglas is a PhD Candidate in the Langille Lab in the Deptartment of Microbiology and Immunology at Dalhousie University. His background is in human genetics and he has just published an intriguing paper called “Re-evaluating the relationship between missing heritability and the microbiome” in the journal Microbiome. He helps listeners understand the basics regarding the issue by explaining heritability as the proportion of variation in a phenotype in a given population explained by genetic variance. He offers more background to this standard and then explains the “case of the missing heritability,” which basically indicates the variation that isn't explained. Several hypotheses have emerged to explain this missing heritability, several of which are tied to the human microbiome. He describes how, for example, a holobiont model of a human organism puts forward a hologenome—a combined genome that includes the microbiome and might capture the missing heritability. The article discusses this theory and points out ways it doesn't quite fit. For example, the holobiont doesn't present a combined evolutionary unit that transmits over generations. But he does think the microbiome plays a role in this mystery. He explains how and why and different ways scientists use these ideas.

Abstract: Clusterwise inference is a popular approach in neuroimaging to increase sensitivity, but {most existing methods are} currently restricted to the General Linear Model (GLM) for testing mean parameters. Statistical methods for variance components testing, which are critical in neuroimaging studies that involve estimation of narrow-sense heritability or test-retest reliability, are seriously underdeveloped due to methodological and computational challenges, which would potentially lead to low power. We propose a fast and powerful test for variance components called CLEAN-V ('CLEAN' for testing 'V'ariance components). CLEAN-V models the global spatial dependence structure of imaging data and computes a locally powerful variance component test statistic by data-adaptively pooling neighborhood information. Correction for multiple comparisons is achieved by permutations to control family-wise error rate (FWER). Through analysis of task-fMRI data from the Human Connectome Project across five tasks {and comprehensive data-driven simulations}, we show that CLEAN-V outperforms existing methods in detecting test-retest reliability and narrow-sense heritability with significantly improved power, with the detected areas aligning with activation maps. The computational efficiency of CLEAN-V also speaks of its practical utility, and it is available as an R package. Copy rights belong to original authors.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: Heritability, Behaviorism, and Within-Lifetime RL, published by Steven Byrnes on February 2, 2023 on LessWrong. I'm a firm subscriber to both: (A) The theory that people's personalities are significantly predictable from their genes, and mostly independent of how their parents raised them (at least within the typical distribution, i.e. leaving aside cases of flagrant abuse and neglect etc.). See e.g. popular expositions of this theory by Judith Harris or by Bryan Caplan for the fine print. (B) The theory that we should think of people's beliefs and goals and preferences developing via within-lifetime learning, and more specifically via within-lifetime Model-based Reinforcement Learning (details), with randomly-initialized (“learning-from-scratch”) world-model and value function. I feel like there's an idea in the air that these two beliefs are contradictory. For example, one time someone politely informed me that (A) is true and therefore obviously (B) must be false. Needless to say, I don't think they're contradictory. Indeed, I think that (B) naturally implies (A). But I admit that they sorta feel contradictory. Why do they feel that way? I think because: (A) is sorta vaguely affiliated with cognitive science, evolutionary psychology, etc. (B) is sorta vaguely affiliated with B.F. Skinner-style behaviorism, .and those two schools-of-thought are generally considered to be bitter enemies. In this short post I want to explain why we should put aside that baggage and see (A) & (B) as natural allies. Two dubious steps to get from (B) to Behaviorism Here's the fleshed-out argument as I see it: I'll go through the two dubious steps in the opposite order. Dubious step #1: “No more learning / unlearning after the kid grows up” Here are two stories: “RL with continuous learning” story: The person has an internal reward function in their head, and over time they'll settle into the patterns of thought & behavior that best tickle their internal reward function. If they spend a lot of time in the presence of their parents, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function in the presence of their parents. If they spend a lot of time hanging out with friends, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function when they're hanging out with friends. As adults in society, they'll gradually learn patterns of thought & behavior that best tickle their innate internal reward function as adults in society. “RL learn-then-get-stuck” story: The kid learns patterns of thoughts & behavior in childhood, and then sticks with those patterns for the rest of their lives no matter what. Claim: I think the “RL with continuous learning” story, not the “RL learn-then-get-stuck” story, is how we should generally be thinking about things. At least in humans. (Probably also in non-human animals, but that's off-topic.) I am not making a strong statement that the “RL learn-then-get-stuck” story is obviously and universally wrong and stupid nonsense. Indeed, I think there are edge cases where the “learn-then-get-stuck” story is true. For example, childhood phobias can sometimes persist into adulthood, and certainly childhood regional accents do. Some related discussion is at Scott Alexander's blog post “Trapped priors”. Instead, I think we should mainly believe the “RL with continuous learning” story for empirical reasons: Heritability studies: See top. More specifically, note that (IIRC) parenting style can have some effect on what a kid believes and how they behave while a child, but these effects fade out when the kid grows up. Culture shifts: Culture shifts are in fact possible, contrary to the “RL learn-then-get-stuck” story. For example, almost everybody in the USA opposed gay marria...

Alexander Young is a researcher at the UCLA Anderson School of Management Genomics Department and School of Medicine's Human Genetics Department, working with the Social Science Genetic Association Consortium (SSGAC). He studies the genetics of cognitive ability and educational attainment, with a particular focus on developing methods to uncover true measures of heritability for important traits.Richard and Alexander talk about why siblings are so useful for this purpose, in the midst of a larger overview of the history of behavioral genetics and modern methods. Twin and adoption studies show much higher levels of heritability than genome wide association studies (GWAS). Why might this be the case? Different theories are discussed, along with ways to solve seeming discrepancies.The conversation goes on to cover the societal relevance of Alexander's work, and attempts to isolate research on genes and cognitive ability within the academy.Listen in podcast form or watch on YouTube:Links:* Alexander's Twitter account.* Alexander Young, “Solving the Missing Heritability Problem.”* Alexander Young and co-authors, “Deconstructing the Sources of Genotype-Phenotype Associations in Humans.”* James Lee, “Don't Even Go There.” Get full access to Center for the Study of Partisanship and Ideology at www.cspicenter.com/subscribe
If one of your family members has a mental illness, does that mean you're more likely to have it too? Can you inherit a mental illness from a parent? If your mom has, let's say, social anxiety disorder, and you do too, does that mean that she passed it down genetically or that because she didn't take you out much, and you watched her being nervous around other people- that you learned to be anxious around other people? In this podcast we're going to talk about heritability estimates- what the research has to tell us about how much genes contribute to mental health. You'll learn which disorders have the highest rates of heritability and how understanding this can help you make better choices. Looking for affordable online counseling?

Dr. Uchiyama explains the cultural psychobiological framework. We talk about aspects of behavior genetics that get reframed in this framework, like heritability, the environment, gene-environment interactions, and gene-environment correlations. We discuss issues with the generalizability of genetic effects across societies and across time, and predicting how heritability should differ between societies, between socioeconomic levels, and other groupings within the same society. We get into the specific example of IQ, and the Flynn effect. We also talk a bit about personality variation across societies, and limitations with the Big Five personality inventory. -- A HUGE THANK YOU TO MY PATRONS/SUPPORTERS: KARIN LIETZCKE, ANN BLANCHETTE, PER HELGE LARSEN, LAU GUERREIRO, JERRY MULLER, HANS FREDRIK SUNDE, BERNARDO SEIXAS, HERBERT GINTIS, RUTGER VOS, RICARDO VLADIMIRO, CRAIG HEALY, OLAF ALEX, PHILIP KURIAN, JONATHAN VISSER, JAKOB KLINKBY, ADAM KESSEL, MATTHEW WHITINGBIRD, ARNAUD WOLFF, TIM HOLLOSY, HENRIK AHLENIUS, JOHN CONNORS, PAULINA BARREN, FILIP FORS CONNOLLY, DAN DEMETRIOU, ROBERT WINDHAGER, RUI INACIO, ARTHUR KOH, ZOOP, MARCO NEVES, COLIN HOLBROOK, SUSAN PINKER, PABLO SANTURBANO, SIMON COLUMBUS, PHIL KAVANAGH, JORGE ESPINHA, CORY CLARK, MARK BLYTH, ROBERTO INGUANZO, MIKKEL STORMYR, ERIC NEURMANN, SAMUEL ANDREEFF, FRANCIS FORDE, TIAGO NUNES, BERNARD HUGUENEY, ALEXANDER DANNBAUER, FERGAL CUSSEN, YEVHEN BODRENKO, HAL HERZOG, NUNO MACHADO, DON ROSS, JONATHAN LEIBRANT, JOÃO LINHARES, OZLEM BULUT, NATHAN NGUYEN, STANTON T, SAMUEL CORREA, ERIK HAINES, MARK SMITH, J.W., JOÃO EIRA, TOM HUMMEL, SARDUS FRANCE, DAVID SLOAN WILSON, YACILA DEZA-ARAUJO, IDAN SOLON, ROMAIN ROCH, DMITRY GRIGORYEV, TOM ROTH, DIEGO LONDOÑO CORREA, YANICK PUNTER, ADANER USMANI, CHARLOTTE BLEASE, NICOLE BARBARO, ADAM HUNT, PAWEL OSTASZEWSKI, AL ORTIZ, NELLEKE BAK, KATHRINE AND PATRICK TOBIN, GUY MADISON, GARY G HELLMANN, SAIMA AFZAL, ADRIAN JAEGGI, NICK GOLDEN, PAULO TOLENTINO, JOÃO BARBOSA, JULIAN PRICE, EDWARD HALL, HEDIN BRØNNER, DOUGLAS P.

Welcome to The Nonlinear Library, where we use Text-to-Speech software to convert the best writing from the Rationalist and EA communities into audio. This is: The heritability of human values: A behavior genetic critique of Shard Theory, published by Geoffrey Miller on October 20, 2022 on The Effective Altruism Forum. Overview (TL;DR): Shard Theory is a new approach to understanding the formation of human values, which aims to help solve the problem of how to align advanced AI systems with human values (the ‘AI alignment problem'). Shard Theory has provoked a lot of interest and discussion on LessWrong, AI Alignment Forum, and EA Forum in recent months. However, Shard Theory incorporates a relatively Blank Slate view about the origins of human values that is empirically inconsistent with many studies in behavior genetics indicating that many human values show heritable genetic variation across individuals. I'll focus in this essay on the empirical claims of Shard Theory, the behavior genetic evidence that challenges those claims, and the implications for developing more accurate models of human values for AI alignment. Introduction: Shard Theory as an falsifiable theory of human values The goal of the ‘AI alignment' field is to help future Artificial Intelligence systems become better aligned with human values. Thus, to achieve AI alignment, we might need a good theory of human values. A new approach called “Shard Theory” aims to develop such a theory of how humans develop values. My goal in this essay is to assess whether Shard Theory offers an empirically accurate model of human value formation, given what we know from behavior genetics about the heritability of human values. The stakes here are high. If Shard Theory becomes influential in guiding further alignment research, but if its model of human values is not accurate, then Shard Theory may not help improve AI safety. These kinds of empirical problems are not limited to Shard Theory. Many proposals that I've seen for AI ‘alignment with human values' seem to ignore most of the research on human values in the behavioral and social sciences. I've tried to challenge this empirical neglect of value research in four previous essays for EA Forum, on the heterogeneity of value types in humans individuals, the diversity of values across individuals, the importance of body/corporeal values, and the importance of religious values. Note that this essay is a rough draft of some preliminary thoughts, and I welcome any feedback, comments, criticisms, and elaborations. In future essays I plan to critique Shard Theory from the perspectives of several other fields, such as evolutionary biology, animal behavior research, behaviorist learning theory, and evolutionary psychology. Background on Shard Theory Shard Theory has been developed mostly by Quintin Pope (a computer science Ph.D. student at Oregon State University) and Alex Turner (a post-doctoral researcher at the Center for Human-Compatible AI at UC Berkeley). Over the last few months, they posted a series of essays about Shard Theory on LessWrong.com, including this main essay here , ‘The shard theory of human values' (dated Sept 3, 2022), plus auxiliary essays such as: ‘Human values & biases are not accessible to the genome' (July 7, 2022), ‘Humans provide an untapped wealth of evidence about alignment' (July 13, 2022), ‘Reward is not the optimizer' (July 24, 2022), and ‘Evolution is a bad analogy for AGI: Inner alignment' (Aug 13, 2022). [This is not a complete list of their Shard Theory writings; it's just the set that seems most relevant to the critiques I'll make in this essay.] Also, David Udell published this useful summary: ‘Shard Theory: An overview' (Aug 10, 2022). There's a lot to like about Shard Theory. It takes seriously the potentially catastrophic risks from AI. It understands that ‘AI alignment with human values' requires some fairly well-developed notions about where human values come from, what they're for, a...
赵志磊,康奈尔大学神经生物学博士后蚊子有多烦人呢?试想夏日晚风,你躺在床上正要睡着,这时候传来“嗡~~~”,这恐怕是很多人的噩梦。它会嚣叫着飞到你身边,不经意地咬你一口,然后迅速躲闪。蚊子为什么这么爱咬人?为什么它们即使在黑夜里也能精准地识别到哪里有人?赵志磊研究了6年蚊子。他发现蚊子的大脑是靠气味区分人和其他动物的。那么人和动物的气味有什么不一样?蚊子如何分辨这些气味?世界上有3500多种蚊子, 专门咬人的蚊子其实不足10种,这些蚊子是怎么进化出对人类的“偏爱”呢?为什么有的人容易被蚊子咬?除此之外,蚊子还会传播病毒。新冠会通过蚊子传播吗?我们要不要消灭蚊子?一个没有蚊子的世界,真的会更好吗?赵志磊将带着他的研究为我们揭开这些问题的谜底。【时间轴】01:37不是所有蚊子都咬人03:59养蚊子和收集气味07:54人类的气味有什么秘密?10:12蚊子的大脑在想什么?给蚊子做开颅手术20:05为什么有的人特别招蚊子?21:20蚊子是慢慢进化成咬人专业户的24:18蚊子的存在有意义吗?【参考文献】[1] Zhao, Z., Zung, J.L., Hinze, A. et al.

In this episode of the Epigenetics Podcast, we caught up with Marcela Sjöberg from the University of Chile to talk about her work on the hydroxymethylation landscape in immune cells. At the beginning of her career Marcela Sjöberg worked on Polycomb and how modifications placed by this complex modulate the binding of RNA Pol II. Later, her focus shifted to hydroxymethylated cytosine and how it is involved in the inheritance of Metastable Epialleles in mouse. More recently, the laboratory is interested in transcription factor binding motifs and how hydroxymethylation of those binding motifs modulates the binding and activity of the respective transcription factors.

Huberman Lab Podcast Notes Key Takeaways Manic episodes are the defining criteria of bipolar disorder AKA bipolar depression – not all people with bipolar disorder experience deep depressionTypes of bipolar disorder: (1) Bipolar I – characterized by an extended period of mania (elevated mood, impulse, distractibility, etc.) – the mania is extreme and noticeable to people around; (2) Bipolar II – characterized by swings of hypomania (lessened intensity of mania or shorter duration of mania) and depressive episodesBipolar I presents itself more overtly because of bouts of mania; Bipolar II can duck under the radar because of the intense depressive state and hypomania which might look more normal compared to a depressive stateHeritability of bipolar disorder among the general population is 85% – if someone has bipolar disorder, it's likely they inherited a gene, set of genes, or susceptibility in genes to influences that can trigger bipolar disorderMajor neurological deficits in people with bipolar disorder: (1) lack of internal awareness (interoception); (2) top-down control on overall levels of energy (reduction in connectivity between parietal region and limbic system)Treatment approaches need to be comprehensive and in combination – for example, lithium + talk therapy“It's naïve and in fact, wrong, to say that lifestyle interventions alone are going to prevent especially extreme forms of mania and depression.” – Dr. Andrew HubermanRead the full notes @ podcastnotes.orgIn this episode, I explain the biology, symptoms, causes and types of bipolar disorder (sometimes called bipolar depression). I discuss neuroplasticity and how the brain normally regulates mood, energy, and perceptions; then, I contrast that with the biology of bipolar disorder, which is characterized by extremes of energy and mood, e.g., mania and depression. I outline the mechanisms through which bipolar disorder manifests in the brain, including deficits of interoception and reduced connections between the parietal and limbic systems. I also outline how treatment options (such as lithium) work in part through homeostatic plasticity.' I discuss not only lithium but also the treatment of bipolar with ketamine, different talk therapies, electroconvulsive therapy, transcranial magnetic stimulation, and nutraceuticals, including Omega-3 and Inositol supplementation. This episode should interest anyone who has or knows someone with bipolar disorder and, more broadly, those interested in how the brain works to create a balance between thoughts, energy levels, focus, and mood.

In this episode, Jess and Sara finally (Finally!) tackle the basic premise of behavior genetics. We talk about what kinds of research questions you can ask with genetically sensitive designs, describe what heritability is and what it's not, and discuss just how it's possible that scientists can use data from twin pairs to understand how much of the variance in some skill or behavior is due to genes and how much is attributable to the environment. A lot of that estimate depends on just how much genes and environments vary within a twin pair and between twin pairs (see what we did there?). In this episode we talked about: Sara's paper with the figures that Jess describes: https://www.nature.com/articles/s41539-020-00079-z/figures/3 Here's a cool introductory paper written for Frontiers for young minds that covers much of this introductory content: https://kids.frontiersin.org/articles/10.3389/frym.2019.00059 Connect with the podcast on twitter @within_between, or email us letters about developmental science at withinandbetweenpod@gmail.com.

Separation Anxiety: Myth Busting with Malena DeMartinihttps://malenademartini.com/ (Malena DeMartini), canine behavior specialist focused on separation anxiety, joins host Laura Reeves for some mythbusting around anxiety, separation anxiety, genetics and heritability of anxieties and fears, and more. “When we're talking with regard to separation anxiety, your dog is not being a jerk,” DeMartini said. “Nor are they being spiteful. Nor are they just angry at you because you're not spending enough time with them. All of that discussion, that is not what's happening. What is happening is so important that we understand from a compassion and empathy standpoint, as well as from a training standpoint. These dogs are panicked. This is a true phobia to being left alone. I want to remind people that, by definition, phobias tend to be rather irrational, or at least irrational to the person that's not experiencing that. It really isn't your fault“Spoiling, and this is how they represent spoiling: letting a dog sleep on the bed, letting a dog on the furniture, giving them lots of treats or feeding them extra goodies, or taking them on car rides with us, all these sorts of activities, which in my head are part of having a family member, none of those things are either causational or correlational for separation anxiety. “When you have a dog with separation anxiety, you are going to get every naysayer in the universe coming after you saying it is your fault … I just want people to absolve themselves from that guilt and no they did not create an animal with separation anxiety by letting him snuggle on the couch.” Don't "feed the beast"DeMartini also offered recommendations on how to not “feed the beast” of a dog's anxiety. “When I talk about nonchalant exits and entries, we have to remember that dogs are masters of discrimination. Yes, they know when we're leaving and so taking an extra five minutes to give them kissy sounds can just put more emphasis on the exit. So, I tell people your dog has figured out that you put on your shoes, you've grabbed your backpack, got your keys in your hand, your dog is fully aware that you're about to leave, you don't have to tell him anything. All in the family?DeMartini provided insight on the genetics and epigenetics of anxiety and fear in dogs, as well. “In the last few years (researchers) have actually identified a haplotype, so sort of a genetic marker, that is specifically in accordance with separation anxiety. Here is the important aspect: just because (a dog has) that particular haplotype, where those genetic markers exist, does not mean that the behavior problem is going to occur. That's where the epigenetics play a role. These are like toggle switches. So that toggle switch may remain off for the lifetime of that animal but there are some environmental influences that could flip that toggle switch. “You can have the most beautiful well-bred dog physically, but if they are suffering from a welfare perspective because of their mental health that's a problem. Behavior modification“Separation anxiety is actually a behavior that is quite modifiable. It's not easy and it takes time, but we can do a lot to optimize dogs for a long-term success in the beginning of their lives. Just because there's that genetic potential predisposition, that doesn't mean that we can't change it. Heritability is not a diagnosis of a permanent state. “Separation anxiety behaviors are evolutionarily appropriate for puppies at a young age. How many of us have seen a puppy cry and the bitch comes back. We've seen it over millions of years of evolution that there is a purpose for vocalization and some of these other behaviors when these pups are really, really young. But the majority of them do grow out of it. If they don't it's become sort of maladaptive. When it becomes maladaptive in a 14 or 16 or 18 week pup, no amount of letting them cry it out and try and get over it is going to help them grow out of it. That... Support this podcast
Michael Shermer is one of the world's most prominent skeptics - founder of The Skeptic Society and editor of its magazine Skeptic. Once a fundamentalist Christian, Michael has spent his career uncovering the workings and causes of our 'Believing Brain'.“Our brains are wired to think more like lawyers than scientists - to win arguments, to bolster what we already believe...”We evolved to discern patterns in the world around us. When our ancestors ate the wrong mushroom, they very quickly learnt to link it to their upset stomach. Discovering patterns is the way humans learn. But humans are sometimes too good at it: we ‘discern' patterns where none exist, and we infuse them with agency.Listen to Michael and Turi discuss the two key evolutionary drivers of belief:Patternicity - our tendency to find patterns in both meaningful and meaningless data.Agenticity - our tendency to infuse patterns with meaning, intention, and agency.And learn more about:The evolutionary origins of beliefWhere conspiracy theories come fromDopamine: the belief drugWhat Twin Studies teach us about the Heritability of beliefHow to keep a healthy mindAnd B.F Skinner's famous pigeon experiment, which shows all animals exist on the belief spectrum.“Belief comes quickly and naturally, skepticism is slow and unnatural, and most people have a low tolerance for ambiguity.”Michael ShermerMichael Shermer is a science writer, historian of science, founder of The Skeptics Society, and editor-in-chief of its magazine Skeptic. He's also the author of The Believing Brain and most recently, Giving the Devil his Due on the free speech wars raging across the West.More on this episodeLearn all about the Parlia Podcast here.Meet Turi Munthe: https://www.parlia.com/u/TuriLearn more about the Parlia project here: https://www.parlia.com/aboutAnd visit us at: https://www.parlia.com See acast.com/privacy for privacy and opt-out information.

Abstract: Human brain plastically adapts to environmental demands. Here, we propose that naturally occuring plasticity in certain brain areas should be reflected by higher environmental influence and therefore lower heritability of the structure of those brain areas. Mesulam's (1998) seminal overview proposed a hierarchy of plasticity, where higher-order multimodal areas should be more plastic than lower-order sensory areas. Using microstructural and functional gradients as proxies for Mesulam's hierarchy, we seek to test whether these gradients predict heritability of brain structure. We test this model simultaneously across multiple measures of cortical structure and microstructure derived from structural magnet resonance imaging. We also account for multiple other explanations of heritability differences, such as signal-to-noise ratio and spatial autocorrelation. We estimated heritability of brain areas using 984 participants from the Human Connectome Project. Multi-level modelling of heritability differences demonstrated that heritability is explained by both signal quality, as well as by the primary microstructural gradient. Namely, sensory areas had higher heritability and limbic/heteromodal areas had lower heritability. Given the increasing availability of genetically informed imaging data, heritability could be a quick method assess brain plasticity. Copy rights belong to original authors.

1. I have been a proponent of wholesome eating as the guarantee of good health and optimal weight. The approach has worked great for me, but I am still curious to know if eating high caloric density foods – but within strict daily caloric “budget” – is detrimental to one’s health? I have no cravings or addictions of any sort, it is almost an “academic” question mostly concerning socially inflicted foods like BBQ, wine, cheese, etc. 2. My girlfriend often slips into baby talk — and it grates on my nerves, but I don’t know how to stop it. Any suggestions? 3. I’m wondering, why we’re having so many beautiful women in Russia, but much less of handsome men. Is there any explanation? 4.Plomin states that the heritablity of weight is 70%. Is this statistic a byproduct of our modern food environment and therefore an explanation of the obesity problem? How would the heritability of weight differ in a stone-age environment? How would it differ if we measured a cohort from Chef AJ's group? That word heritability, is also confusing. Please explain. 5. Whats up with corporate jargon, like "Could you action this item?", buzz words like "synergy", being told to "think outside the box", needlessly fancy job titles and the like. I realize it's bound to be several things: conferring status cheaply, trying to motivate by conveying positivity, obfuscating to avoid concrete promises and cover asses, trying to sound smart and adjusting language use to match the in-group. Am I mistaken or missing anything? Where does this jargon come from -is it perpetuated by business schools or the fanciest companies? Am I penalizing myself significantly if I don't go along with all this BS?
Part two of Oprah’s discussion with Pulitzer Prize-winning writer Isabel Wilkerson and readers about the book, Caste: The Origins of our Discontents. The second episode in the eight-part series focuses on the second pillar of Caste, “Heritability”; the idea that permanent rank in society is inherited and passed down through ancestry. Special guest Academy Award winning actor Forest Whitaker joins the conversation. Oprah and Isabel respond to questions and comments from readers on the second pillar.

Gavin Douglas and colleagues published a paper assessing microbiome research and assertions that the human microbiome explains missing heritability in nature. He discusses this issue and explains What are classic ways of understanding genetic variation in humans and how recently microbiome research has entered this understanding, What the holobiont model is and how it involves claims regarding the microbiome and missing heritability in nature, and How their paper views the microbiome as more of potential element in genetic variation in humans and necessitates more consideration regarding how to integrate it outside of the strict, holobiont model. Gavin Douglas is a PhD Candidate in the Langille Lab in the Deptartment of Microbiology and Immunology at Dalhousie University. His background is in human genetics and he has just published an intriguing paper called “Re-evaluating the relationship between missing heritability and the microbiome” in the journal Microbiome. He helps listeners understand the basics regarding the issue by explaining heritability as the proportion of variation in a phenotype in a given population explained by genetic variance. He offers more background to this standard and then explains the “case of the missing heritability,” which basically indicates the variation that isn't explained. Several hypotheses have emerged to explain this missing heritability, several of which are tied to the human microbiome. He describes how, for example, a holobiont model of a human organism puts forward a hologenome—a combined genome that includes the microbiome and might capture the missing heritability. The article discusses this theory and points out ways it doesn't quite fit. For example, the holobiont doesn't present a combined evolutionary unit that transmits over generations. But he does think the microbiome plays a role in this mystery. He explains how and why and different ways scientists use these ideas.

Abstract: SNP heritability of a trait is measured by the proportion of total variance explained by the additive effects of genome-wide single nucleotide polymorphisms (SNPs). Linear mixed models are routinely used to estimate SNP heritability for many complex traits. The basic concept behind this approach is to model genetic contribution as a random effect, where the variance of this genetic contribution attributes to the heritability of the trait. This linear mixed model approach requires estimation of relatedness among individuals in the sample, which is usually captured by estimating a genetic relationship matrix (GRM). Heritability is estimated by the restricted maximum likelihood (REML) or method of moments (MOM) approaches, and this estimation relies heavily on the GRM computed from the genetic data on individuals. Presence of population substructure in the data could significantly impact the GRM estimation and may introduce bias in heritability estimation. The common practice of accounting for such population substructure is to adjust for the top few principal components of the GRM as covariates in the linear mixed model. Here we propose an alternative way of estimating heritability in multi-ethnic studies. Our proposed approach is a MOM estimator derived from the Haseman-Elston regression and gives an asymptotically unbiased estimate of heritability in presence of population stratification. It introduces adjustments for the population stratification in a second-order estimating equation and allows for the total phenotypic variance vary by ethnicity. We study the performance of different MOM and REML approaches in presence of population stratification through extensive simulation studies. We estimate the heritability of height, weight and other anthropometric traits in the UK Biobank cohort to investigate the impact of subtle population substructure on SNP heritability estimation.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.07.30.229914v1?rss=1 Authors: Zhao, B., Li, T., Smith, S. M., Xiong, D., Wang, X., Yang, Y., Luo, T., Zhu, Z., Shan, Y., Hauberg, M. E., Bendl, J., Fullard, J. F., Roussos, P., Lin, W., Li, Y., Stein, J. L., Zhu, H. Abstract: Human brain has a complex functional architecture and remains active during resting conditions. Resting-state functional magnetic resonance imaging (rsfMRI) measures brain activity at rest, which is closely linked with cognition and clinical outcomes. The role of genetics in human brain function is largely unknown. Here we utilized rsfMRI of 44,190 multi-ethnic individuals (37,339 in the UK Biobank) to discover the common genetic variants influencing intrinsic brain activity. We identified and validated hundreds of novel genetic loci associated with intrinsic functional signatures (P < 2.8 * 10^{-11}), especially for interactions of the central executive, default mode, and salience networks involved in the triple network model of psychopathology. A number of intrinsic brain activity associated loci had been implicated with brain disorders (e.g., Alzheimer's disease, Parkinson's disease, schizophrenia) and cognition, such as 17q21.31, 19q13.32, and 2p16.1. Genetic correlation analysis suggested the shared genetic influences among intrinsic brain function, brain structure, and brain structural connectivity. We also detected significant genetic correlations with 26 other complex traits, such as education, cognitive performance, ADHD, major depressive disorder, schizophrenia, sleep, and neuroticism. Heritability of intrinsic brain activity was enriched in brain tissues. The reported risk genes of Alzheimer's disease typically had stronger associations with intrinsic brain activity than brain structure, and the associated genes of intrinsic brain activity were enriched in multiple biological pathways related to nervous system and neuropathology (P < 1.8 * 10^{-9}).

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.07.30.229427v1?rss=1 Authors: Anderson, K. M., Ge, T., Kong, R., Patrick, L. M., Spreng, R. N., Sabuncu, M. R., Yeo, B. T. T., Holmes, A. Abstract: Human cortex is patterned by a complex and interdigitated web of large-scale functional networks. Recent methodological breakthroughs reveal variation in the size, shape, and spatial topography of cortical networks across individuals. While spatial network organization emerges across development, is stable over time, and predictive of behavior, it is not yet clear to what extent genetic factors underlie inter-individual differences in network topography. Here, leveraging a novel non-linear multi-dimensional estimation of heritability, we provide evidence that individual variability in the size and topographic organization of cortical networks are under genetic control. Using twin and family data from the Human Connectome Project (n=1,023), we find increased variability and reduced heritability in the size of heteromodal association networks (h2: M=0.33, SD=0.071), relative to unimodal sensory/motor cortex (h2: M=0.44, SD=0.051). We then demonstrate that the spatial layout of cortical networks is influenced by genetics, using our multi-dimensional estimation of heritability (h2-multi; M=0.14, SD=0.015). However, topographic heritability did not differ between heteromodal and unimodal networks. Genetic factors had a regionally variable influence on brain organization, such that the heritability of network topography was greatest in prefrontal, precuneus, and posterior parietal cortex. Taken together, these data are consistent with relaxed genetic control of association cortices relative to primary sensory/motor regions, and have implications for understanding population-level variability in brain functioning, guiding both individualized prediction and the interpretation of analyses that integrate genetics and neuroimaging.

Abstract: How much of our visual processing, and thus our visual perception, is inherited? Variations in perceptual judgments of the size of visual objects have been found to correlate with idiosyncratic differences in the spatial sensitivity of primary visual cortex. Here we tested their heritability using retinotopic mapping and psychophysical experiments on size perception. The spatial sensitivity of human visual cortex, quantified by population receptive field analysis, was more similar in monozygotic (MZ) than dizygotic (DZ) twin pairs, especially in extrastriate regions, suggesting a partial genetic determination. Furthermore, inter-individual differences in perceptual bias for size judgments - how large or small stimuli appear to an observer - showed considerable heritability. This contrasts with previously reported idiosyncrasies across visual field quadrants, which showed little evidence of heritability. Our findings are therefore consistent with heritability of broad, eccentricity-dependent properties of visual function and cortical architecture, while quadrant-specific idiosyncrasies appear to lack a genetic basis.

True Crime Psychology and Personality: Narcissism, Psychopathy, and the Minds of Dangerous Criminals
This episode covers how to tell the difference between a psychopath and a narcissist, and what causes narcissistic personality disorder. When we use the term psychopath, we're talking about some who has trait psychopathy and when we use the term narcissist, we're talking about someone who has trait narcissism. Narcissism has two types: grandiose and vulnerable. Primary psychopathy has characteristics like being callous, unemotional, pathological lying, being manipulative, and being bold (fearless dominance). Secondary psychopathy has characteristics like being irresponsible, being impulsive, having a need for stimulation, and being involved in activities that could result in arrest. Grandiose narcissism has fantasies of success and power, jealousy, a sense of entitlement, arrogance, and being manipulative. With vulnerable narcissism, we see some of the same characteristics like insecurity, hypersensitivity to criticism, shame, guilt, and sadness.Oftentimes an individual with Narcissistic Personality Disorder wants to be recognized as superior, believes they are so complex and amazing that they can only be understood by special people, has low self-esteem, devalues the contributions of others, and is condescending. Criticism is not well received by most people with Narcissistic Personality Disorder. The prevalence of Narcissistic Personality Disorder is about 1%.Heritability accounts for somewhere between 40% and 65% to the development of NPD. Some structural changes in the brain have also been identified. Experiences in early childhood may also contribute to the development of narcissistic personality disorder. Risk factors include when a child receives excessive praise and also excessive criticism, lack of parental empathy, praise for abilities or appearance instead of other characteristics, and an emphasis on status or achieving success. Other potential ideological factors include emotional abuse and neglect.00:30 - How to Tell the Difference Between a Psychopath and a Narcissist21:00 - What Causes Narcissistic Personality Disorder More Content on Narcissism, Psychopathy, Sociopathy and Antisocial Personality DisorderFor even more, scientifically informed content on psychology and personality check out Dr. Grande's YouTube channelArs Longa MediaTo learn more about or to support Ars Longa Media and this podcast, go to arslonga.media.

Hey ADDers! Do you ever wonder about the heritability of ADHD or how your emotions and feelings impact your executive functioning? In fact, do you know the difference between your emotions and your feelings? If yes and no, this episode is for you!! According to Pema Chodron, an American Tibetan Buddhist and ordained nun, if you allow an emotion to exist for 90 seconds without judging it, it will disappear. According to Jill Bolte Taylor, a neuroanatomist and author of A Brain Scientist’s Personal Journey, “once triggered, the chemical released by your brain surges through your body and you have a physiological experience. Within 90 seconds from the initial trigger, the chemical component of anger has completely dissipated from your blood and your automatic response is over. If, however, you remain angry after those 90 seconds have passed, then it is because you have chosen to let that circuit continue to run.” In this episode, I talk about: The Heritability of ADHD The 90-Second Rule Executive Functioning Emotions Feelings The importance of celebrating your WINS To Help The Show: If you like what I'm doing here on the show, please leave a review on Apple Podcasts and share with your community via social media Ratings and reviews are extremely helpful and greatly appreciated.

So, the question I have for you at this point of our journey together is, “What is the big goal you need to set so you can grow into the person who can achieve it? And, are you going to get yourself the support and training you need to become that person?” I hope so; and perhaps ADDventures in Achievement is the place to be so you can become that person with the support of our community and training I provide.

Sue Langley, is a speaker, master trainer, global business consultant and leading advisor, and founder and CEO of the Langley Group of Companies. Sue has taught thousands of business leaders how to create positive work-places. Sue Langley’s website: http://suelangley.com/ In this discussion, you will learn about creativity and innovation and how they benefit us as individuals, but also how organizations can foster creativity and innovation beyond just having “a culture of creativity.”You will hear Sue’s thoughts on how leaders and organizations can develop the right climate for creativity and innovation to flourish. Sue shares a lot of valuable information on her approach with leaders and organizations. You will learn the vocabulary she uses, and how she convinces organizations to be open to the science and research of positive psychology. Sue also shares a recent example of an organization that wasn’t ready for these practices. You’ll Learn: [1:43] - Having a culture of creativity in an organization isn’t enough to foster innovation and creativity. [2:31] - Sue describes two types of creativity and innovation. [3:25] - The benefits of creativity. [4:25] - Sue shares what research says about creativity. [6:26] - How leaders and organizations can develop the right climate for creativity to flourish. [10:29] - Sue talks about how she convinces leaders and organizations to be open to the science and research of positive psychology. [11:31] - How to implement these changes into an organization. [13:07] - The vocabulary used with organizations when introducing positive psychology and wellbeing. [13:43] - The relationship between positive psychology and profitability. [14:34] - When positive psychology practices aren’t the best fit for an organization. [15:59] - Sue talks about individuals and organizations with too much creativity.

More than a quarter of people are affected by anxiety or depression each year. But are some people more at risk than others? By studying groups of rhesus monkeys, Dr Ned Kalin from the University of Wisconsin in Madison found that individuals displaying a trait known as "anxious temperament" may be up to 50% more likely to go on to develop anxiety disorders later in life, and the same seems to be true in humans...

Is blonde and red hair attractive because of how it looks, or because it’s rare? Also, “my genes made me do it”: can men (or women) blame their cheating ways on their genetic inheritance? And we also continue last month’s foray into the murky world of mate-poaching, and discover the differences between the sexes when it comes to detecting potential partner pilferers. Download the MP3Rate me! Rate, review, or listen in iTunes or in Stitcher. Some have theorised that red and blonde hair is attractive because it is rare. New research by Zinnia Janif tests this idea.

Radiation sensitivity is assumed to be a cancer susceptibility factor due to impaired DNA damage signalling and repair. Relevant genetic factors may also determine the observed familial aggregation of early onset lung cancer. We investigated the heritability of radiation sensitivity in families of 177 Caucasian cases of early onset lung cancer. In total 798 individuals were characterized for their radiation-induced DNA damage response. DNA damage analysis was performed by alkaline comet assay before and after in vitro irradiation of isolated lymphocytes. The cells were exposed to a dose of 4 Gy and allowed to repair induced DNA-damage up to 60 minutes. The primary outcome parameter Olive Tail Moment was the basis for heritability estimates. Heritability was highest for basal damage (without irradiation) 70% (95%-CI: 51%-88%) and initial damage (directly after irradiation) 65% (95%-CI: 47%-83%) and decreased to 20%-48% for the residual damage after different repair times. Hence our study supports the hypothesis that genomic instability represented by the basal DNA damage as well as radiation induced and repaired damage is highly heritable. Genes influencing genome instability and DNA repair are therefore of major interest for the etiology of lung cancer in the young. The comet assay represents a proper tool to investigate heritability of the radiation sensitive phenotype. Our results are in good agreement with other mutagen sensitivity assays.

Objective: Genome-wide association studies have identified robust associations between single nucleotide polymorphisms and complex traits. As the proportion of phenotypic variance explained is still limited for most of the traits, larger and larger meta-analyses are being conducted to detect additional associations. Here we investigate the impact of the study design and the underlying assumption about the true genetic effect in a bimodal mixture situation on the power to detect associations. Methods: We performed simulations of quantitative phenotypes analysed by standard linear regression and dichotomized case-control data sets from the extremes of the quantitative trait analysed by standard logistic regression. Results: Using linear regression, markers with an effect in the extremes of the traits were almost undetectable, whereas analysing extremes by case-control design had superior power even for much smaller sample sizes. Two real data examples are provided to support our theoretical findings and to explore our mixture and parameter assumption. Conclusions: Our findings support the idea to re-analyse the available meta-analysis data sets to detect new loci in the extremes. Moreover, our investigation offers an explanation for discrepant findings when analysing quantitative traits in the general population and in the extremes. Copyright (C) 2011 S. Karger AG, Basel
