[Influence of various tasks on activation and self-evaluation in a test with equal psychomotor performance]

In two tests, healthy individuals had to perform one tapping-task each. In the first test they had to knock as quickly as possible (without feedback via the motor performance), while in the second test the motor performance of the first experiment was reproduced precisely by means of feedback allowing them to evaluate the result of their action. In the second experiment, the individuals were significantly less activated, and they felt the second task was easier, requiring less performance. The effect of feedback upon the course of activation, and the role of sensation of activation by the individual in judging his own performance are described.
