Research Abstract

In two experiment, the effect of existence of friend on cardiovascular response and subjective affect were examined. In the first experiment, participants executed mental arithmetic task with/without friend. Cardiovascular responses (HR, SBP, DBP, CO, TPR) were recorded throughout experiment and subjective affects were assessed befor rest and after task. Only in subjective affect(anxiety or startle), friend existence condition difference were found. In the second experiment, participant executed speech task and they spent after task period with/without mobile phone communication with friend. In addition to prior experiment, skin conductance and skin blood flow were recorded. Also in experiment 2, we found condition difference only in subjective affect(but in positive affect). We didn't found any statistically significant differences in peripheral autonomic responses, but in some indices, friend existence seemed to induce lower reactivity.
