Are reinforcement learning models complete accounts of decisions from experience if they ignore explicit memory?
In this new preprint, we show that people indeed form robust explicit memory representations that flexibly guide later decisions.

Check out @bcdavidson.bsky.social's preprint (w/ @georgiaturner.bsky.social @orbenamy.bsky.social @livia-tomova.bsky.social and co.) about the (computational) consequences of social isolation in social media use during covid!
🚨 New Preprint 🚨
Prolonged Isolation is associated with an increased behavioural sensitivity to ‘Likes’ on social media.
🧵
Social media rewards are inherently social—but does posting change during social isolation, when in-person social rewards are limited?
It turns out, yes!
