Anticipatory autonomic response to a public speaking task in women: the role of trait anxiety.

The aim of this research was to study anticipatory autonomic responses their relationship to trait anxiety. Twenty-three women prepared an evaluated speech (S-condition) and 22 women an evaluated essay (W-condition). Heart rate (HR), finger pulse volume (FPV) and skin conductance were recorded before, during and after preparation of the task and during task performance; state-anxiety was evaluated before and after the task. In the total sample, state-anxiety was higher in the S- than in W-condition and this anxiety increase was accompanied by FPV reductions. However, when the sample was split according to trait anxiety scores, HR during preparation and increases of state-anxiety were greater in S- than W-condition in only in high-anxious women. Results suggest that specificity of anticipatory HR response to a public speaking task in women is moderated by cognitive anxiety.
