| Research Abstract |
We investigated the mechanisms of performance deterioration due to psychological variations such as pressure and nervousness in human movement execution. As typical examples, we measured body responses of competitors of piano competition. Results demonstrated that, when they played before audience and judges, the heart rate increased, low-amplitude electromyoygraphic activity was tonically enhanced, fine motor control of fingers was disordered, and performance evaluation was degraded. As a possible brain mechanism subserving these phenomena, modification of amygdala activity by dopamine was proposed through animal experiments.
