The purpose of this study is to examine how human performance organized by motor learning is reorganized through changes in the central program and structural parameter by using a tracking task of serial pattern. On the one hand, the subjects who had to adjust themselves to the changed central program (program group)tried to execute the corresponding switch responses coincident with light onsets in 20 trials in the first half and tried to complete perfectly with anticipatory response in 20 trials in the second half. On the other hand, the subjects who had to adjust themselves to the changed structural parameter (parameter group) tried to execute the corresponding switch responses coincident with light onsets in 40 trials. The serial patterns which subjects tracked were 352415 in the program group and 352415 in the first half of the parameter group and 352451 in the second half of that group., The stimulus interval(100 ms)and the interstimulus interval(400 ms)were always constant. The subjects were 20 right-handed female students, being randomly assigned to the 2 groups with 10subjects respectively. In both groups, the proportion of correct responses amounted approximately to 70〜90% of the total response in the first half. Both groups increased the correct and anticipatory responses in the final phase of the first half. The program group, however, remarkably decreased the correct responses (7.03%) and markedly increased the anticipatory responses (42.16%) in the final phase of the second half. The program group in the first half was different from the one in the second half in structuring its own performance. In the parameter group, on the other hand, the performance in the final phase of the second half (anticipatory response : 25.00%)was higher than that of the first half (anticipatory response : 4.46%) although the performance without anticipatory response in the initial phase of the second half was lower than the one in the final phase of the first half. This finding was taken as an order through fluctuation.
