Research in the Niv lab focuses on the neural and computational processes underlying reinforcement learning and decision-making. We study the ongoing day-to-day processes by which we learn from trial and error, without explicit instructions, to predict future events and to act upon the environment so as to maximize reward and minimize punishment. In particular, we are interested in how attention and memory processes interact with reinforcement learning to create representations that allows us to learn to solve new tasks so efficiently.

Mar 2021: Congratulations to Dan, Gili and Gina for doing so well on the PhD-interview circuit! Not that we are surprised, but always nice to see others recognize your awesomeness as well!

Feb 2021: Congratulations to Kelsey McDonald, former undergrad in the lab, on defending her thesis at Duke Institute for Cognitive Science. So proud of you! Check out Kelsey's amazing work here, and here is a great starting point.

Jan 2021: Congratulations to Eran Eldar and Valkyrie Felso on their paper “A pupillary index of susceptibility to decision biases”, now published in Nature Human Behavior! Our first attempt at a registered report, this was quite a learning experience, not to mention a tour de force of running scores of subjects with eye tracking (thanks, Val!). And we may be breaking our own records of older work being published after many years – this project was one of Eran’s graduate work projects!
