This study was designed to examine whether the subjects could learn to discriminate their alpha activity from non-alpha activity by integrated alpha technique. A total of 26 subjects were assigned to either the experimental group or the yoked control group by pair-matching the amounts of alpha wave. Both groups received three 5 min feedback training sessions to increase the alpha activity. In these sessions, the experimental subjects were given contingent feedback signals to their amount of alpha wave, while the control subjects were given non-contingent feedback signals. In the pre-and post-feedback sessions, the subjects' discriminabilities of alpha activity, either presence or absence, were measured 60 times respectively. The results showed that the experimental subjects significantly improved their discriminative accuracy across the trials, although the yoked control subjects provided no improvement of accuracy. Noteworthily, the experimental subjects significantly increased their amount of alpha wave during the feedback sessions.
