概要	Across two studies, this research tested whether pre-existing reinforcement-learning bias predicts responses to acute stress. Participants completed a probabilistic selection task, a socially evaluated cold-pressor procedure, fear acquisition, and a card-sorting measure of flexibility. Under stress, reinforcement-biased participants showed stronger skin-conductance responses to nonthreatening cues during fear learning; the comparable pattern was not evident for punishment-avoidance bias. Learning bias did not predict stress-related changes in cognitive flexibility, although stress itself impaired flexibility. The findings link reward-learning style selectively to fear generalization under stress rather than to executive adaptation.
