Building and Breaking the Chain: A Model of Reward Prediction Error Integration and Segmentation of Memory Abstract. Prediction errors drive reinforcement learning and organize episodic memory into distinct contexts, but do these effects interact? Here, we review the roles of midbrain dopamine, the locus c...

There are salient updates to attend to BUT if you’re wondering how they organize your memory, here’s a review/simulation offering diff. roles of prediction errors in building & breaking our models of the world w/ @davidclewett.bsky.social @jameswardantony.bsky.social inspired by Sarah DuBrow (1/7)

The title of the paper, "Beliefs about Perception Shape Perceptual Inference: An Ideal Observer Model of Detection", with the author names, and Fig. 1: a schematic of an inverse optics account of vision.

Our "I would have seen it if it were there" paper — a collaboration with @ranimo.bsky.social and @clarepress.bsky.social — is now out in Psych. Review.

There’s a lot in this paper, but here are what I see as the 3 main takeaways:

How to communicate the value of curiosity-driven research The burden of proof is on us, as researchers, to explain why what we do is valuable to society.

Terrific how-to on communicating the value of basic research to the public in @thetransmitter.bsky.social by @tonyzador.bsky.social.

You may be curious. But when you are communicating the value of what you do, it’s not about you. Point to discoveries.
