In this paper, we present the results of a study to determine the effect of the P300-based brain-computer interface (BCI) virtual reality game on the cognitive functions of healthy human subjects. This study is a part of on-going research related to evaluation of the long-term effect of P300 training in Virtual Reality surrounding (VR game) on the cognitive performance of the young healthy population. A comparison of results between 3 groups of participants (15 people each) revealed the progressing difference in cognitive assessment for experimental group played P300-BCI VR game, showing the positive increase in flanker and conjunction visual search task performance associated with selective attention and mental inhibition. We show that the effect is due to the use of P300 BCI paradigm. Our results suggest that P300 BCI games combined with virtual reality can not only be used for rehabilitation in patients with slight mental disorders or elderly, but for increasing some cognitive functions in healthy subjects, giving an additional improvement in learning in case of combination with possible educational tasks or used for attention training.

玩基于P300的BCI VR游戏会导致健康成年人的认知功能发生变化

在本文中，我们提出了一项研究结果，以确定基于P300的脑机接口（BCI）虚拟现实游戏对健康人类受试者的认知功能的影响。这项研究是正在进行的与评估P300虚拟现实环境（VR游戏）培训对年轻健康人群的认知表现的长期影响相关的研究的一部分。通过对三组参与者（每人15人）的结果进行比较，发现实验组玩过P300-BCI VR游戏的认知评估的进步差异，表明侧翼和与选择性注意和精神抑制相关的联合视觉搜索任务性能正向增加。我们证明了效果是由于使用了P300 BCI范例。
