Gender differences in cardiovascular and electrodermal responses to public speaking task: the role of anxiety and mood states.
Gender moderates psychophysiological responses to stress. In addition to the hormonal background, different psychological states related to social stressors, such as anxiety and mood, could affect this response. The purpose of this study was to examine the existence of gender differences in the cardiovascular and electrodermal responses to a speech task and their relationship with anxiety and the mood variations experienced. For this, non-specific skin conductance responses (NSRs), heart rate (HR), and finger pulse volume (FPV) were measured at rest, and during preparation, task and recovery periods of an academic career speech in undergraduate men (n=15) and women (n=23), with assessment of changes in the state version of the State-Trait Anxiety Inventory (STAI-S) and in the Profile of Mood States (POMS) questionnaires. Men and women did not differ in trait anxiety, hostility/aggressiveness, or in the appraisal of the task, which were evaluated with the trait version of the State-Trait Anxiety Inventory (STAI-T), the Buss and Durkee Hostility Inventory (BDHI), and a self-report elaborated by ourselves, respectively. Women had higher FPV in all periods except during the task, and were more reactive to the stressor in state anxiety, and in the amplitude of NSRs. No gender differences for HR and for the frequency of NSRs were found. Anxiety and mood states were differently related to cardiovascular and electrodermal measurements in men and women. Further studies should consider the hormonal variations in addition to the psychological dimensions, in order to offer a more integrative perspective of the complex responses to stress.
