No reversal with instructions: Instructed Group learners

Collection: Instructed knowledge shapes feedback-driven aversive learning in striatum and orbitofrontal cortex, but not the amygdala

Description: No reversal with instructions (main effect of CS without interaction; i.e. [previous CS+ > previous CS-] ∪ [new CS- > new CS+]). Regions that show no evidence for reversal when instructions are delivered, based on continued differential responses pre- and post-instruction. Regions in warm colors showed greater activation to the pre-instruction CS+ relative to the CS- both pre- and post-instruction, while regions in cool colors show relatively greater activation to the CS- (or deactivation to the CS+). Map depicts t-test across learners, or those individuals who showed differential SCR prior to the first reversal (n = 20).
