Bio:

Yael Niv received her MA in Psychobiology from Tel Aviv University and her PhD in Computational Neuroscience from the Hebrew University in Jerusalem, having conducted a major part of her thesis research at the Gatsby Computational Neuroscience Unit in UCL. She is currently a professor at Princeton University, at the Psychology Department and the Princeton Neuroscience Institute. Her lab studies the neural and computational processes underlying reinforcement learning and decision making, with a particular focus on how the cognitive processes of attention, memory and learning interact in constructing task representations that allow efficient learning and decision making. She is co-founder and co-director of the Rutgers-Princeton Center for Computational Cognitive Neuropsychiatry, where she is applying ideas from reinforcement learning to questions pertaining to psychiatric disorders within the new field of computational psychiatry. 

Abstract:

Latent causes, prediction errors, and the organization of memory      

In recent years, my lab has suggested that incoming information is parsed into separate clusters ("states" in reinforcement learning parlance) -- all events that are assigned to one cluster are learned about together, whereas events in different clusters do not interfere with each other in learning. Moreover, we have suggested that prediction errors are key to this separation into clusters. In this talk, I will revisit these ideas building not only on behavioral experiments showing evidence for clustering, but also experiments that show the effects of prediction errors on episodic memory. I will attempt to tie the different findings together into a hypothesis about how prediction errors affect not only learning, but also the organization of memory.
