During the biofeedback training, some healthy subjects haven't their motivation to control the state of their health. In such a case, the effect of the training seems to different from one's participating volition in the training. It is know that conscious perception derived from some sensory input is signalled to the profrontal lobes. The pathway would be mainly through the hypothalamus and the limbic system. These systems modify with emotion the conscious perceptions and then superimpose on them motivational or participating volition. The volition is based on individual feedforward functions of the nervous system - innate and acquired. We have researched alpha activity enhancement using auditory alpha feedback. Subjects' conscious perception played an important role in alpha activity enhancement. To help forward on subjects' alpha activity enhancement when they received the feedback signals, we previously experimented the scoring feedback technique and derivative feedback technique. In this study, we noticed on the relationship between alpha activity enhancement and alpha feedback information quantity. In Session 1,we examined each subject's percent time alpha(PTA) base line and set up each threshold level. And then we used two feedback methods, the first, in Session 2,we gave each subject the feedback information only when his PTA is rising over the threshold level, and the second, in Session 3,only when it is descending below the level. The subject whose basic alpha amplitude is small or whose basic PTA is low comparatively can't be given so many information in Session 2,but can be given many information in Session 3. Otherwise the subject whose basic alpha amplitude is large or whose basic VFA is high can be given the information conversely. We divided the subjects in the above-mentioned two groups, and performed the experiments respectively. In thede experiments, we took notice the following problems, (1) the relationship between each subject's PTA and feedback information quantity, (2) each subject's emotional change when he received a rewarding feedback information(in Session 2) and otherwise a warning information(in Session 3), (3) the effect of participating volition to enhance alpha activity. The resuits of our experiments suggested as follows. (1) We have to use a feedback technique which give individually the subject adaptive feedback information in case of feedback training, (2) Most subjects feel comfortably when they received rewarding informations, and feel unpleasantly when they received warning informations. (3) Participating volition plays an very important role in alpha activity enhancement.
