Very excited to share our first effort-learning paper in
@plosbiology.org! Huge thanks to my wonderful co-authors @Jan Grohn, @thepsychologist.bsky.social and to my co-senior authors @mkflugge.bsky.social and @lilweb.bsky.social, for all their effort on this fun project.

This follows-up on our paper on how basis functions guide social decision-making, now investigating individual differences in social basis function use. While having autistic traits does not change these computations, being young does: see work with @simyciri.bsky.social: osf.io/preprints/ps...
New preprint from the lab! Here, @yongling.bsky.social shows that people prioritise self / ingroup-related information to guide their decisions - irrespective of their autistic traits.
Original paradigm and approach first published here: www.nature.com/articles/s41...
Our paper revealing the evolutionary origins of metacognition-driven human intelligence in the macaque brain is just out in Nature Human Behaviour rdcu.be/fji6p

📣 New preprint 📣
"Neural Dynamics of Belief and Value Computations Guiding Strategic Social Decisions"
We use EEG and computational modeling (combining learning + DDM) to explain participants' choices, RT, and neural signals in a strategic game.

Anna Schroeder, neuberufen an der LMU, erforscht, wie das Gehirn Emotionen, Bedürfnisse und Motivation in Handlungen übersetzt – und wie es Verhalten an wechselnde Umweltbedingungen anpasst.
Successful strategic behavior must be grounded in beliefs about the opponent and her intentions. While many potential models have been proposed to explain choices in such situations, the neural mechanisms that govern learning and choice in complex strategic contexts remain poorly understood. Here, we use a computational model that combines dynamic learning and choice mechanisms to explain both choices and response times of human participants engaged in a competitive strategic task. Using electroencephalography (EEG), we identify temporally structured stages of neural processing that support an evolving value-based decision process, corresponding to first- and second-order belief updates and evidence accumulation related to the comparison of action values. Gamma-band phase coupling between central and parietal EEG signals varied with individual winning rate, suggesting that strategic behavior involves coordinated information transfer across spatially remote areas. Together, our data characterize the temporally evolving neural dynamics of belief and valuation processes that underlie strategic choice and provide neural validation for assumptions embedded in computational models of this behavior. ### Competing Interest Statement The authors have declared no competing interest.

We show preserved self–other integration in social decision-making among individuals with elevated autistic traits (N = 1,621), highlighting the importance of large samples to validate null effects.

Autistic people can find social interactions difficult to navigate, traditionally attributed to difficulties in taking others' perspectives. However, we have a limited understanding of how autistic pe...

New preprint www.biorxiv.org/cgi/content/... How does the brain separate "how long was that?" from "was it longer than expected?" We designed a task in which physical duration and categorical judgment vary independently, and used EEG to separate these signals. #neuroskyence #psychscisky 1/8
