🚨 Fully Funded PhD positions Gonda Brain Institute, Sharp Lab We will explore how people build & deploy world models efficiently for planning & deciding. We will also investigate how world model construal & use is biased in anxiety. Deadline: 1 Sept 2025. Please share!
Is risk-taking shaped by decision-making or by learning? In a new @NatureComms paper led by @AlonErdman, we show that in experience-based risk-taking, very little variance is explained by decision-making (top), but a lot is explained by learning (bottom). nature.com/articles/s4146…

Thrilled to share @MatanRubin1 's first empirical paper, just out in @NatureHumBehav. A significant step in understanding how people respond to AI vs human empathy, and what we value in human connection.
🚨New paper Alert! So many people ask AI for emotional support – but is it like support from a human? Our new paper published in @NatureHumBehav explores whether people value #AI - generated #empathy as much as human empathy, in 9 preregistered studies with 6,282 participants.🧵

🚨 now out in @TrendsCognSci: Clinicians noted for decades how planning & anxiety are linked. Yet, computational psychiatry thus far failed to show how. I argue that we need to broaden how we model planning to reveal its *biases* in chronic anxiety: authors.elsevier.com/a/1kAJC4sIRvTB…
