title: Eliciting and maintaining ruminative thought: the role of social-evaluative threat.
abstract: This study tested whether a performance stressor characterized by social-evaluative threat (SET) elicits more rumination than a stressor without this explicit evaluative component and whether this difference persists minutes, hours, and days later. The mediating role of shame-related cognition and emotion (SRCE) was also examined. During a laboratory visit, 144 undergraduates (50% female) were randomly assigned to complete a speech stressor in a social-evaluative threat condition (SET; n = 86), in which an audience was present, or a nonexplicit social-evaluative threat condition (ne-SET; n = 58), in which they were alone in a room. Participants completed measures of stressor-related rumination 10 and 40 min posttask, later that night, and upon returning to the laboratory 3-5 days later. SRCE and other emotions experienced during the stressor (fear, anger, and sadness) were assessed immediately posttask. As hypothesized, the SET speech stressor elicited more rumination than the ne-SET speech stressor, and these differences persisted for 3-5 days. SRCE-but not other specific negative emotions or general emotional arousal-mediated the effect of stressor context on rumination. Stressors characterized by SET may be likely candidates for eliciting and maintaining ruminative thought immediately and also days later, potentially by eliciting shame-related emotions and cognitions.
