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

Description: Correlations with instructed reversal (ρ) parameters. Brain-behavior correlations tested for correlations between each individual’s ρ parameter (based on within-subjects fits) and the magnitude of the reversal effect (CS x Phase interaction) using robust regression. Regions in warm colors show positive correlations between the magnitude of the instructed reversal parameter and the strength of reversal (Top) or sustained differential response (Bottom) in the region, while regions in cool colors show negative correlations. This analysis was restricted to Instructed Group learners (n = 20) who showed differential SCR prior to the first reversal.
