Abstract
The relation between each subject's feedforward and feedback function was investigated in this experiment. Ten subjects were divided into two groups, FF-Group and noFF-Group. Subject FF-Group were intentionally given several exemplary percent time alpha(PTA) changes prior to each training. These changes were expected to results in improvements in the subjects' feedforward function. This procedure is the same as supervised learning. On the other hand, subjects noFF-Group were not given the above exemplary PTA changes, but just carried on with each feedback training. In these experiments, on average active alpha in subjects FF-Group was more enhanced than in the other group. From the results, it was suggested that appropriate feedforward function raises confidence and plays an important role in alpha activity enhancement, and so feedforward compensated feedback control training is commendable.
