Another preprint! This one from my postdoc with @ignaciosaezphd.bsky.social and @xiaosigu.bsky.social. Here we asked how the reward outcomes driving trial-by-error learning leave a lasting imprint on memory strength in the human brain. We used iEEG/computational models of cognition to find:

It took me a while to cover from this, but what a memorable week filled of exciting science, fun conversations, and soccer at #CPC2026 !! Thank you everyone for making it all the way to New Haven from all over the world. Until next time!! www.cpconf.org #ComputationalPsychiatry

What a week! #CPC2026 was amazing, and it was such a joy to co-organize & host it here at Yale with @robbrutledge.bsky.social @xiaosigu.bsky.social @yiplab.bsky.social @francesghart.bsky.social & Al Powers & Katie Myerscough (our MVP!) Some highlights... 🧵

📢 New preprint out now! In three samples (N=594), including a U.S.-representative cohort and a test-retest cohort, we formalize social motivation, learning, and homeostatic control within a single computational framework and identify a phenotype linked to chronic loneliness doi.org/10.31234/osf...

Thank you all for helping repost this ad.🙏 We've received many excellent applications! 🙌 Just wanted to clarify that *prior experience working with human participants* is required (data analysis per se is not counted as experience with human participants). Please consider your fit accordingly~

1/6 Excited to see our NMH paper featured here for #WorldMentalHealthDay! rdcu.be/dYl7T Many psychiatric symptoms are inherently social. @xiaosigu.bsky.social, @joebarnby.com, & I call for cognitive models that reflect processes most relevant to our questions, esp. for those about social symptoms🧵
