The present study was to determine whether the EEG biofeedback training could affect the behavioral measures of finger tapping interval and pressure. In Experiment 1 the alpha bidrectional controls of increase and decrease were given to 18 college sutdents to observe the following behavioral modification of tapping. Each subject was undertaken 5 biofeedback training trials of 3 min., tapping being measured in the periods of preceding and following biofeedback training. The results showed that the tapping pressure decreased sigificantly with no difference in training condition, while no marked biofeedback training effect for both directions was appeared. Twenty six subjects were participated in Experiment 2 in order to enhance the effect of alpha biofeedback training using a prolonged period of training. The alpha increase training was given to 16 experimental subjects and to 10 control subjects for 3 days each. The evident effect of alpha increase training was observed in the experimental group with the significant decrease of tapping pressure, while no significant changes in EEG and behavioral measure were obtained for control group. Taken these experiments together, it can be concluded that the EEG biofeedback training can modify the following behavioral measure of tapping pressure, which would imply the useful technique in the clinical field.
