Representational similarity modulates neural and behavioral signatures of novelty

Abstract: Novelty signals in the brain modulate learning and drive exploratory behaviors in humans and animals. The novelty of a stimulus should crucially depend on existing representations in the brain, yet the effect of stimulus representations on novelty computation remains elusive. In particular, existing models of novelty computation fail to account for the effects of stimulus similarities that are abundant in naturalistic environments and tasks. In this talk, I will discuss our recent model that quantifies the effects of stimulus similarities on novelty computation and explains distinct signatures of novelty-related perception and novelty-driven exploration.
