Abstract
Anxiety, generally, consists of the The present study was an attempt to responses to them. Twenty-four male physical-danger situation and the ego-threatening situation. examine the effect of anxiety situations on the expressions of undergraduates served as subjects, who randomly divided into two experimental groups, that is, ES condition as the physical-danger situation which a subject received an electric shock as a noxious stimulus, and PV one as the ego-threatening situation which he was observed by TV-camera while he was waiting for the presentation of pornographic film. Heart rate and tapping pressure were used as measures of anxiety responses. Response variability was calculated by FFT. Relationship between anxiety responses was analyzed by cross correlation method, Response levels tended to increase in ES condition, while heart rate variability (HMO of low frequency (0.008-0.05 Hz) did in PV condition. As the result of cross correlation, high correlation was observed between HRV ranged from 0.058 Hz to 0.1 Hz and tapping pressure only in ES condition. These results showed that the expressions of anxiety responses varied with anxiety situations.
