摘 要: 研究采用真实的剪刀石头布游戏范式,基于脑电图(electroencephalogram,EEG)分析非平局(输、赢)情况下的对抗认知,对游戏中各脑区活动的EEG信号分别进行频域和时域分析。频域分析结果表明:随着频率的增加,脑电信号的能量整体上呈现递减趋势,其中α和β波段的能量较为接近;θ,α和β波段能量在上一轮输的情况下显著高于上一轮赢的情况。时域分析结果表明:颞区和顶区在博弈过程中相关性较强。验证了前额叶在决策过程中的主导作用,并且由频域分析结果可知:上一轮输的被试在下一轮游戏中想要赢的欲望或许更加强烈。所得结果为脑认知的研究提供了参考。
关 键 词: 计算机应用;博弈;脑电图;频域分析;时域分析

Abstract: This paper adopts real rock-scissor-paper game paradigm and is based on the competition reaction from electroencephalogram (EEG) analysis under different condition (lose, win), and the game of the brain activity of EEG signal for every frequency domain and time domain is analysized. Frequency domain analysis results show that with the increase of frequency, the brain electrical signal on the energy of the whole presents a decreasing trend, the α and β band energy are relatively similar. θ, α and β band energy under the condition of the last round of lose is significantly higher than the previous situation of winning. The time domain analysis results show that the temporal region and district have strong correlation in the process of game. The prefrontal leading role is verified in the decision-making process, and the frequency domain analysis results show that the previous round participants who losed may have a bigger desire to win in the next round of in the game. The result provides references for the brain cognitive research.
