Abstract：To assess the effects of virtual reality movement on human cognitive performance.30 healthy college students were recruited randomly, 20 of them (experiment group) were given 6 weeks of virtual reality movements on a idong king Ⅱ(stretching, archery and balancing), 30 min each time, three times a week, while the rest of ten students (control group) had a normal schedule.Adopting Germany-made BP 32 Brain Vision Analyzer and modified Flanker stimulus paradigm, ERP P300 at resting state before and after the experiment were respectively measured.Descriptive and inferential statistics analysis were respectively conducted on received data using SPSS15.0 for Windows.According to the paired t test in the group after six weeks, under consistency stimulation (S1 and S2),ERP P300 latency period of both the frontal area (F3 and F4) and central (C3) electrode point was both longer than that before the experiment(P<0.05),and the change of the frontal zone was more marked;ERP P300 amplitude in the top area (P3) under S1 stimulation had a significant increase than that before the experiment (P<0.05).No significant change was seen for both the control group and experiment group in other electrode areas under other ways of stimulation (P>0.05).Six weeks virtual reality movements (stretching, archery and balancing) have certain selective effects on college students'' cognitive performance, which is showed by the fact that significant changes in ERP P300 latency and amplitude index occur only in specific brain zones under specific stimulation;P300 latency change only appears in the frontal and the central zones, and P300 amplitude change only appears in the top zone, and both occur under consistency stimulation only.Therefore, these selective changes can be seen as adaptive changes to the given movement patterns.
