Basis functions for complex social decisions in dorsomedial frontal cortex - Nature
A study combining group decision-making tasks with fMRI shows that the brain’s dorsomedial prefrontal cortex uses basis functions, similar to those in the visual, motor and spatial domains, to re...
www.nature.com
New paper from our lab now in @nature.com . We show that our brains use basis functions or "building blocks" to navigate social interactions. Rather than tracking every individual separately, social information is compressed into patterns that can be flexibly combined. www.nature.com/articles/s41...

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... ).

Internal uncertainty impacts social information use in risky choice across adolescence - Communications Psychology
Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.
