New preprint 📝 - another fun collaboration with @arikahn.bsky.social, @licezhang.bsky.social, @nathanieldaw.bsky.social, @hartleylabnyu.bsky.social We ask: Why do children and adults often derive different representations of their environments from the same experiences? 🧠👶🔎 osf.io/preprints/ps...

Should you stick to your goal, try something else, or give up? Your median raphe nucleus in the brainstem knows and will decide for you 😉. First foray of my lab into foraging, behavioural strategies and exploration. Amazing work from the one and only Mehran Ahmadlou: www.nature.com/articles/s41...

Using an RL task that manipulates people's beliefs about agency, we show that exposure to & severity of early-life adversity is associated with lower learning rates & agency beliefs. w/ the brillant @thephelpslab.bsky.social, Kate McLaughlin, & Bryan Dong learnmem.cshlp.org/content/32/1...

psyarxiv.com/y3dzn preprint from the time i spent at @hartleylabnyu.bsky.social 💜 - we were puzzled by past findings suggesting that children learn about the structure of the world, but don't use this knowledge to flexibly guide their decision-making as much as adults do.

“… I explore the practical implications of admitting that there are no biological essences of many psychiatric conditions. If, for example, depression turns out to be more like divorce than it is like Huntington’s disease. For one thing, there would still be opportunity for palliative approaches.”
