1. Loading a sequential repetitive click sound signal with a constant frequency of 1.3 Hz, 10 healthy subjects were made to perform jaw tapping movement. They were instructed to adjust their movement so as to be obtained a coincidentaneous tooth contact with the signal, and after cessation of signal, which was unable to anticipate for subject, to cease their movement as soon as possible. 2. After cessation of the signal, all subjects made one surplus tapping movement without the signal. 3. Regarding DPSP of Mm, IPS of Da and TCPS, no significant difference was found between the last tapping with signal and the surplus tapping without signal (P>0.25). 4. DOSP of Mm, IOS of Da and TCOS in the surplus tapping were to be longer significantly than the corresponding value in the tapping with the last signal (P<0.001). 5. It could be interpreted that these change of tapping movement should be done by "an instant performance control" and this control should be essential to perform the task in the shortest time with minimum energy consumption.
