Abstract Individuals exhibit variability in their propensity to learn from observing others’ behaviors. Here we investigated how individual differences in adopting others’ decisions influence both their own choices and subsequent memory for contextual information. In an fMRI-based probabilistic reinforcement-learning task, participants were tasked with either making choices or observing decisions between visual cues, leading to either congruent or opposing outcomes.

Abstract To cope in uncertain environments, animals must balance their actions between using current resources and searching for new ones1. This exploration–exploitation dilemma has been studied extensively in paradigms involving positive outcomes, and neural correlates have been identified in frontal cortices and subcortical structures2,3,4,5,6,7,8,9,10,11, including the amygdala12.
