The purpose of this study were to investigate the effects of a procedure to raise one's perceived self-efficacy and to examine the influence of the fluctuation of perceived self-efficacy upon the following behavioral changes. Ten subjects, 20:09 - 28:01 years old, were randomly assigned to the self-efficacy manipulating condition (experimental condition) with false biofeedback or control condition. In the experimental condition, Ss were asked to increase their heart rate for a minutes per one trial. In the first ten trials, false HR feedback was given to Ss as the increasing sign of heart rate, independently of their real changes in heart rate. Ss were asked to evaluate their strength of perceived self-efficacy to the task before every trial, and then verbal persuasion was given by an experimenter after the tenth trial. In the last five trials, Ss were given no feedback informations. In the control condition, Ss were also asked to increase their heart rate, but with no feedback informations and no chance to estimate own strength of perceived self-efficacy till the tenth trial. The last five trials were as same as in the experimental condition. The main results were as follows: i) In the experimental condition, false feedback caused the significant increase of self-efficacy score after the tenth trial (see Fig. 2). ii) The experimental group showed significantly more increase in heart rate than Ss in the control condition, especially in the last five trials, which were followed by the increase of self-efficacy score (see Fig. 3). iii) The fluctuation of self-efficacy score caused the change of heart rate and self-efficacy was regarded as the proceeding factor to predict the following behavioral changes (see Fig. 4). These results suggests the importance of perceived self-efficacy as an intervening factor between the treatment and real behavioral changes. If one gained the feeling of performance accomplishments by feedback informations, whether they are true or false, it would be possible to strengthen his or her l
