Abstract
Recalling happy memories elicits positive feelings and enhances one’s wellbeing, suggesting a potential adaptive function in using this strategy for coping with stress. In two studies, we explored whether recalling autobiographical memories that have a positive content—that is, remembering the good times—can dampen the hypothalamic–pituitary–adrenal axis stress response. Participants underwent an acute stressor or control task followed by autobiographical memory recollection (of only positive or neutral valence). Across both studies, recalling positive, but not neutral, memories resulted in a dampened cortisol rise and reduced negative affect. Further, individuals with greater self-reported resiliency showed enhanced mood, despite stress exposure. During positive reminiscence, we observed engagement of corticostriatal circuits previously implicated in reward processing and emotion regulation, and stronger connectivity between ventrolateral and dorsolateral prefrontal cortices as a function of positivity. These findings highlight the restorative and protective function of self-generated positive emotions via memory recall in the face of stress.
