Polczynska, M. Abstract: A brain tumor in the left hemisphere can decrease language laterality as assessed with fMRI. However, it remains unclear whether or not this decreased language laterality is associated with a structural reshaping of the grey matter, particularly within the language network. Here, we examine if the disruption of language hubs exclusively affects macrostructural properties of contralateral homologues (as suggested by previous research), or whether it affects both hemispheres. This study uses voxel-based morphometry applied to high-resolution MR T1-weighted MPRAGE images from 31 adult patients left-dominant for language. Eighteen patients had brain tumors in the left hemisphere, and 13 had tumors in the right hemisphere. A cohort of 71 healthy individuals matched on age and sex was used as a baseline. We defined 10 ROIs per hemisphere known to subserve language function. Two separate repeated-measures ANOVAs were conducted with the volume per region as the dependent variable. For the patients, tumor lateralization (right versus left) served as a between-subject factor. The current study demonstrated that the presence of a brain tumor generates a global volumetric change affecting left language regions and their contralateral homologues. These changes are mediated by the lateralization of the lesion. Our findings suggest that compensatory functional mechanisms are supported by the rearrangement of the grey matter, although future longitudinal research should determine the temporal course of such changes.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2022.12.19.521075v1?rss=1 Authors: Markwell, L. T., Cochran, K., Porter, J. M. Abstract: The evolution of virtual reality (VR) has created the opportunity for a relatively low-cost and accessible method to practice motor skills. Previous studies have demonstrated how motor skill practice in non-immersive virtual environments transfers to physical environments. Though minimal research has investigated motor learning and transfer within immersive VR, multiple experiments provide empirical evidence of positive transfer effects. To enhance the similarities between virtual and physical environments, most studies have used software engines and modified hardware. However, many learners and practitioners are currently using commercially available VR with the goal of enhancing real-world performance, though there is very little evidence to support the notion of positive transfer for these systems. Therefore, the purpose of this experiment was to investigate how motor skill practice using a commercially available VR system improved real-world performance and how that compared to physical practice. Participants (n = 68) were randomly selected into one of two groups: virtual reality (VR) practice (n = 33) or real-world (RW) practice (n = 35). The experiment took place over two consecutive days with a pretest, posttest, and practice phase occurring on both days. The pre- and post- testing phases were identical for both groups and consisted of putting a golf ball 10 times on a carpeted surface towards the center of a target. The practice phases consisted of 60 total putts per day in the respective environment (VR or RW). Participants continuously alternated golf putting holes from three different distances until they accrued 60 total putts. Participants in the RW group performed golf putts to three targets. Participants in the VR group also performed golf putts on three different miniature golf putting holes, using the commercially available Oculus Rift and the Cloudlands VR Minigolf game. The VR putting targets were designed to replicate the putting holes in the physical environment. Separate 2 (condition) x 4 (test phase) repeated measures ANOVAs were used to assess accuracy and club head kinematics. The results revealed a significant main effect for test phase, but not for condition. Post hoc analyses revealed both groups significantly improved their putting accuracy and club head kinematics at similar rates. The results from this study indicate that the transfer of learning that occurred from the commercially available VR practice was equally effective when compared to RW practice.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.09.24.311118v1?rss=1 Authors: Montijn, J. S., Seignette, K., Howlett, M. H., Cazemier, J. L., Kamermans, M., Levelt, C. N., Heimel, J. A. Abstract: Neurophysiological studies depend on a reliable quantification of whether and when a neuron responds to stimulation. Current methods to determine responsiveness require arbitrary parameter choices, such as binning size. These choices can change the results, which invites bad statistical practice and reduces the replicability. Moreover, many methods only detect mean-rate modulated cells. New recording techniques that yield increasingly large numbers of cells would benefit from a test for cell-inclusion that requires no manual curation. Here, we present the parameter-free ZETA-test, which outperforms t-tests and ANOVAs by including more cells at a similar false-positive rate. We show that our procedure works across brain regions and recording techniques, including calcium imaging and Neuropixels data. Furthermore, in illustration of the method, we show in mouse visual cortex that 1) visuomotor-mismatch and spatial location are encoded by different neuronal subpopulations; and 2) optogenetic stimulation of VIP cells leads to early inhibition and subsequent disinhibition.

Study: Psychological Factors in Ultrarunning Abstract: The psychological processes of ultramarathon runners are not well-understood in the current literature. Previous studies have primarily focused on the physical and physiological components of ultrarunning and the few studies exploring the psychological components of ultrarunning have relied predominantly on retrospective inquiry. The purpose of this study was to use a mixed-methods, multimodal approach to examine the psychological aspects of ultrarunning. “Live” in-task quantitative and video data were collected during the course of a 100 mile and 100 km ultramarathon races that spanned 32 hours of data collection. These data were supplemented with an immediate, short postrace interview directly following the runner completing or withdrawing from the race, and then a second, in-depth interview approximately six weeks following race weekend. For the quantitative data collection, single-item, in-task measures assessed runners’ pain, fatigue, affective valence (i.e., a feeling state of “bad” or “good”), energy, attentional focus, confidence to finish, and perceived exertion. Video cameras were also used to visually record changes the runners experienced during the run. Both postrace interviews were audio recorded, transcribed verbatim, and analyzed with a phenomenological lens. A total of 11 runners in the 100 mile race and five runners in the 100 km race participated in this study; six runners completed the 100 mile race and four runners completed the 100 km race. Due to the lower number of participants in the 100 km race, inferential statistics were completed only with the 100 mile runners. Independent samples t-tests were conducted to examine the mean in-task ratings of finishers and non-finishers in the 100 mile run. Finishers had significantly higher confidence ratings than non-finishers at mile 65 and at mile 75. A series of repeated-measures analyses of variance (ANOVAs) assessed changes in in-task measures over the course of the ultramarathon race for the six finishers in the 100 mile race. There was a significant effect of time on the in-task measures of pain, affective valence, fatigue, energy, and exertion, with pain, fatigue, and exertion increasing and affective valence and energy decreasing over the course of the race. The videos taken during the race were used as memory prompts during the runners delayed postrace interview following race weekend. Phenomenological analysis of the interview transcripts revealed eight major chronological phases depicting the psychological aspects of the runners’ race experience: pre-race, the start, chugging along, getting dark, it gets real, final push, the finish, and post-race reflections. There were also two overarching subthemes identified in analysis that went beyond the chronological phases: the natural environment of the race and the social community of ultrarunning. Implications for theory and practice, as well as suggestion for future studies, are identified and explored.   Author: Dolores Christensen Dolores Christensen was born and raised in Northern California.

What are the defining characteristics of a good psychology study? We received this excellent question from a listener and decided to do a whole episode on this idea. Some of the topics discussed: When’s the last time you saw a psych study that only reported a t-test? Dan and James’ new paper on worry and heart rate variability Skepticism towards studies with many variables and ‘novel’ statistical approaches (that tend to always provide marvellous results) Repeated measures ANOVAs vs. linear mixed models Publishing convenient ideas, even if they’re wrong Fishing expeditions The ‘nocebo’ effect in action What are markers of study quality? Pre-registering studies - can it be gamed? The gradual improvement of psychology studies Links Dan and James' new paper on worry and heart rate variability http://www.ncbi.nlm.nih.gov/pubmed/27255891 The paper that said "Encouraging experimental psychologists to use LMMs was like giving shotguns to toddlers.” http://www.ncbi.nlm.nih.gov/pubmed/25657634 Facebook page https://www.facebook.com/everythinghertzpodcast/ Twitter account https://www.twitter.com/hertzpodcast

This study explores chronotype-dependent tolerance to the demands of working morning, evening, and night shifts in terms of social jet lag, sleep duration, and sleep disturbance. A total of 238 shift-workers were chronotyped with the Munich ChronoType Questionnaire for shift-workers (MCTQ(Shift)), which collects information about shift-dependent sleep duration and sleep timing. Additionally, 94 shift-workers also completed those items of the Sleep Questionnaire from the Standard Shift-Work Index (SSI) that assess sleep disturbances. Although all participants worked morning, evening, and night shifts, subsamples differed in rotation direction and speed. Sleep duration, social jet lag, and sleep disturbance were all significantly modulated by the interaction of chronotype and shift (mixed-model ANOVAs). Earlier chronotypes showed shortened sleep duration during night shifts, high social jet lag, as well as higher levels of sleep disturbance. A similar pattern was observed for later chronotypes during early shifts. Age itself only influenced sleep duration and quality per se, without showing interactions with shifts. We found that workers slept longer in fast, rotating shift schedules. Since chronotype changes with age, investigations on sleep behavior and circadian misalignment in shift-workers have to consider chronotype to fully understand interindividual and intraindividual variability, especially in view of the current demographic changes. Given the impact of sleep on health, our results stress the importance of chronotype both in understanding the effects of shift-work on sleep and in devising solutions to reduce shift-work-related health problems.

Background: Psychoeducational interventions that provide disorder-related information in a goal-oriented and structured manner have been integrated in psychiatric and psychotherapeutic approaches. The present cognitive psychoeducational group programme for inpatients with affective disorders is based on a multidimensional functional illness concept which covers aspects of vulnerability, stressors and coping strategies. It covers information about the disorder and its treatment options, building up rewarding activities, cognitive restructuring and relapse prevention. Materials und Methods: This programme was developed and modified at the University of Munich, Department of Psychiatry (LMU). A feasibility study was set up in a follow-up single group design and analyses of variance (ANOVAs) were performed. A total of 231 patients participated in 46 groups. Results: 125 patients evaluated the effectiveness of the programme and its treatment strategies. The group programme was widely accepted among patients that were pharmacologically and psychotherapeutically treated: more than three quarters of the patients rated its contents to be informative, helpful and applicable to everyday living. Conclusions: Inpatients with affective disorders may already benefit from a structured group programme if it takes into account their cognitive and motivational deficits. The group leaders' didactic and psychotherapeutic strategies as well as the patients' exchanging ideas with each other play a central role. In the course of further investigations the programme was differentiated for patients with major depression or bipolar disorders.
