📣 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. www.biorxiv.org/content/10.6...

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.

I always had the vague feeling that Scientific Reports and Nature Communications are mainly APC business models. A paper estimated the total APC for gold/hybrid Open Access per journal 2015–2018: doi.org/10.1162/qss_... Surprise, surprise - there are 2 outliers at the top😐

In this work, I combined eye-tracking with fMRI to investigate how information search differs between within-domain and across-domain choices in value-based decisions. I also looked at the link between subjective value and neural activity during these decisions.

An interesting must-read spotlight connecting sampling rhythmicity to computational models of decision-making!

Over the past two weeks, I had the great opportunity to present my work at both #SBDM2026 in iconic Paris and #PuG2026 in picturesque Heidelberg. Thank you to the organizers for providing this environment for scientific exchange, and to everyone who stopped by to share their insightful feedback.

🚨New preprint alert🚨 Does hunger affect your decisions beyond food? We tested whether being hungry affects attention & choice across food, intertemporal and social domains. Spoiler: the effects of hunger state on attention and choice are more limited than you might think🧵👇
