Cardiovascular responses to agency and communion stressors in young women

Theory and research (Helgeson, 1994) suggest that women are particularly responsive to communion stressors (i.e., social relationship concerns) as opposed to agency (i.e., achievement and dominance concerns) and that women low in the trait of agency are vulnerable to stress. To test these hypotheses, 60 undergraduate women interacted with a pre-recorded partner; one-third provided support to an interaction partner (i.e., communion stressor), debated current events (i.e., agency stressor), or described a typical day (i.e., control task). Compared to controls, the debate task evoked greater systolic blood pressure and heart rate reactivity and related autonomic changes. Compared to controls, providing support evoked larger increases in cardiac sympathetic activation and reduced vascular resistance. Low levels of trait agency were associated with greater CVR overall. Hence, agency and communion stressors had distinct psychophysiologic effects. Although both tasks heightened reactivity, the agency task evoked cognitive and physiological responses consistent with threat, whereas the communion task evoked a pattern consistent with challenge.
