In contrast to invisible (unacknowledged) social support, visible social support tasks produce exaggerated negative emotional responses. Processes such as social comparison and negative social evaluation confound operationalizations of visible social support. This study tested social support visibility independent of negative social evaluation and social comparison processes, and included cardiovascular responses. Female undergraduates (N = 73) participated in an anticipatory speech task. A female confederate provided either visible or invisible social support, or no social support. Negative emotions were not affected by the social support manipulations. Cardiovascular outcomes were tested by incorporating a series of theoretically driven planned contrasts into tests of stress reactivity conducted through HLM piecewise growth curve modeling. Linear and quadratic trends established cardiovascular reactivity to the task. Further, uncounfounded social support conditions, regardless of visibility, attenuated cardiovascular responses.
