Abstract: The objective of this study was to evaluate the effect of daily life behavior with a secondary task on performance and psychophysiological states. The experiments were based on two conditions: dishwashing (Control) only, and dishwashing while listening to favorite music (Favorite). In the present study, statistical evaluation was conducted to assess the performance and psychophysiological states between the Control and Favorite conditions. As a result, the electromyogram of the ulnar flexor muscle of the wrist in the dominant hand, which is a performance index, showed significant differences between the two conditions. The R-R Interval, which is the physiological index, showed no significant differences between the two conditions. Additionally, the impression of the feelings, which is the psychological index in the Favorite condition were higher than those in the Control condition. Therefore, it is suggested that there is a psychological change as a primary effect of listening to favorite music during daily life behavior, and the performance may be improved as a secondary effect of the psychological change. In conclusion, listening to favorite music decreased the mental fatigue, which is associated with the subjective feelings.
