New study out today in Nature Comms: www.nature.com/articles/s41..., in which we set out to test whether ultrasound could influence the reward-related learning computations of the nucleus accumbens, building on decades of work on dopaminergic prediction error and reinforcement learning. And it did.

This study shows that non-invasive ultrasound to the human nucleus accumbens can modulate deep brain activity and enhance reward-guided learning, offering a potential alternative to invasive neuromodu...

Very proud to be part of this team! 🤓Our new preprint is out, where we examine how social basis functions develop during adolescence. 🥳🥳
🥳!!NEW PREPRINT!!🥳

We show that the tendency to compress complex social information into priors about social structures becomes more pronounced during adolescence.

This study shows that human pairs adopt stable cooperative, competitive, or mixed strategies. A computational model predicts dyadic choices and links these strategies to interaction dynamics, payoffs, and cost of cooperation.

Did cooperation evolve because of conflict? Or is conflict an (avoidable) ‘by-product’ of evolved capacities to cooperate. I think the latter—>

New work with @simyciri.bsky.social. Adults make more accurate decisions than adolescents—yet show more intrusion from irrelevant players. We explain this paradox via efficient information compression: adults rely on combinatorial social basis functions that use group structure as a mental scaffold.

Super pleased with this one, led by the amazing PhD student and foraging expert @emmavscholey.bsky.social!
🧪Preprint!
How foragers depart from optimal models can tell us a lot about how they compute their decisions.

A strong but underexplored departure is that foragers widely vary when they leave identical patches.

In our new paper (open access in PSPB), we asked where children’s greater moral concern for animals stems from. We find that children place less moral weight on species membership alone (i.e. are less speciesist) than adults. #socialpsyc #devpsy #philsky journals.sagepub.com/eprint/ZMRUM...

(1/3) Focused ultrasound stimulation is a versatile neuroscience tool. Depending on parameter settings it can safely and reversibly alter brain function, or it can lead to lasting tissue damage. That’s why we have safety guidelines (see ITRUSST: www.sciencedirect.com/science/arti... ).
