Automated rhythmic movements (tapping) represent a facility for the examination of a motor control subsystem. The actual tapping frequency is influenced by variations of experimental conditions and is related to EEG phenomena. The study deals with the effect of different instructions and additional mental load upon tapping and its relation to EEG rhythms. Depending on instruction, large differences occur between maximum and convenient rhythm, the latter being much slower. If maximum speed is required, the subject produces a higher frequency by its dominant hand; there is no difference between tapping without additional load (non-dominant hand) and with additional load (dominant hand). Previous results concerning the relationship between EEG rhythms and tapping movements could be confirmed.
