Title: Dynamic representations for behavioral flexibility<\/p>\n\n\n\n

When:\u00a0Monday, May 27th, 3.30 pm CET<\/p>\n\n\n\n

Where:\u00a0DZNE building, room 121<\/p>\n<\/div><\/div>\n\n

Abstract: People flexibly adjust their use of information according to context. The same piece of information,\u00a0for\u00a0example the unexpected outcome of an action, might be highly influential on future behavior in one situation — but ignored in another one. Bayesian models have provided insight into why people display this sort of behavior, and even identified potential neural mechanisms that link to behavior in specific tasks and environments, but to date have fallen short of providing broader mechanistic insights that generalize across tasks or statistical environments. Here I’ll examine the possibility that such broader insights might be gained through careful consideration of task structure. I’ll show that we can think about a large number of sequential tasks as requiring the same inference problem — that is to infer the latent states of the world and the parameters of those latent states — with the primary distinctions within the class defined by transition structure. Then I’ll\u00a0talk\u00a0about how a neural network that updates latent states according to a known transition structure and learns „parameters“ of the world\u00a0for\u00a0each latent state can explain adaptive learning behavior across environments and provide the first insights into neural correlates of adaptive learning across environments. Finally, I will present a computational model that can learn the structure of the environment de novo, and show that the model can capture behavioral features of structure learning in humans performing changepoint, oddball, reversal, and sequence tasks.<\/p>\n\n
