Feedback-driven vs Instruction-based expected value: All Instructed Group participants

Contributed by laurenatlas on Feb. 6, 2018

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

Description: Direct comparison between feedback-driven and instruction based EV signaling within the Instructed Group. Feedback-driven EV is based on the model fit to the Uninstructed Group learners, while instruction-based EV is based on fit to the Instructed Group learners. Orthogonalization was disabled in first-level analyses, and these results are robust regression across the contrast values. Regions in warm colors showed preferential correlations with feedback-driven EV, while regions in cool colors showed higher correlations with instruction-based EV. Analysis includes entire Instructed Group (n=30), irrespective of whether participants showed differential SCR prior to the first reversal.
