Autonomic responses to threatening stimuli in relation to the repression sensitization dimension.

Presented 3 neutral and 3 threat-producing pictures to 20 undergraduate sensitizers and 20 repressers, identified by Byrne's Represser-Sensitizer Scale. The GSR was employed to measure RT of the autonomic responses, affective arousal, and recovery time from affective arousal. In addition, the Herr-Kobler psychogalvanometric test of neuroticism was employed to determine the relative autonomic reactivity of the 2 groups. Results indicate no difference in autonomic RT between or within the groups, or in autonomic reactivity on the index of neuroticism. No difference in affective arousal was found between groups, but both repressers and sensitizers showed greater physiological emotional arousal to critical than to neutral pictures. There was no difference in recovery time from affective arousal between groups, but both groups took longer to recover from critical than from the neutral pictures.
