The successor representation subserves hierarchical abstraction for goal-directed behavior
Fig 5
Posterior predictive check of the response time successor representation model within communities.
(A) Layout of the museum with rooms colored according to type. The goal painting is colored black and labeled “G”. Green rooms lie within wings that do not contain the goal painting (“outside”). Blue rooms lie at the boundary between two non-goal wings (“away”). Orange rooms lie at the boundary allowing for a transition into the goal wing (“toward”). Pink rooms lie within the goal wing (“within”). Yellow rooms lie at the boundary allowing for a transition out of the goal wing (“out of”) (B) Mean response times (standardized within participant) in different rooms outside the goal wing, as labeled in A. (C) Same as B, but drawn from posterior predictions of the fitted successor representation for each participant. (D) Same as B, but for rooms inside the goal wing. (E) Same as D, but drawn from posterior predictions of the fitted successor representation for each participant.
