title: Rumination and multi-modal emotional reactivity.
abstract: Rumination, a cognitive process that involves passively and repetitively focusing on negative feelings and their consequences, has been linked to negative emotional outcomes. Previous research suggests that rumination may lead to deleterious outcomes through prolonging emotional reactivity; however, evidence supporting the link between rumination and reactivity has been mixed. In the present study, we examined the relationship between state and trait rumination and multi-modal emotional reactivity (i.e., hypothalamic-pituitary-adrenal axis, autonomic nervous system, subjective experience). Fifty undergraduates participated in a social evaluative laboratory stressor. They also reported on their general tendency to ruminate and their use of rumination in response to this particular laboratory stressor. State, but not trait, rumination was associated with increases in cortisol and negative affect. Findings underscore the importance of multi-modal assessment of emotional reactivity and suggest important implications for rumination following a stressor.
