Abstract
The purpose of this study was to examine the relationship between the performance level and the degree of HR and subjective tension. Subjects performed a short-piece music chosen according to their skills, and their performance were judged by professors. Main findings were as follows. (1) The peak of HR change was seen 1 minute after the performance, whereas that of subjective tension was seen 1 minute before the performance. (2) There was no relationship between the performance level and correlation coefficient as a index of synchrony. (3) But, as the result of cross correlation shifted so that the peaks of HR change and subjective tension might accord with each other, it was observed that synchronous changes produced high level of musical performace. These findings indicated that simultaneous changes of anxiety responses is not a sufficient condition for high performance in test anxiety situation.
