In a previous study, we demonstrated that the mirror neuron system is involved in watching competitive games performed by multiple players [Shimada, S., & Abe, R. (2009). Modulation of the motor area activity during observation of a competitive game. NeuroReport, 20, 979-983]. In the present study, we investigated whether mirror neuron system activity was modulated by the outcome of a competitive game as well as by the spatial relationship between the player and the observer. We measured the activity of motor areas using near-infrared spectroscopy when a subject watched a two-player competitive game, rock-paper-scissors (RPS). Some parts of the motor area that was activated while performing the RPS action were also activated while observing the RPS game. Interestingly, the magnitude of this activity (during observation) was modulated by the outcome and the view of the particular player whom the subject was supporting. In the dorsal anterior region of the motor area measured, the activity was significantly greater when the supported player won rather than when he lost, regardless of the view. It was also greater when the player was presented with an incongruent view than with a congruent view, regardless of the outcome. In contrast, the dorsal posterior region of the motor area was activated only when the supported player won and was observed with a congruent view. We suggest that mirror neuron system activity during observation of a competitive game reflects the subject's internal assimilation of the actions of the observed player.
在之前的研究中，我们证明了镜像神经元系统参与了观看多个玩家进行的竞技比赛[Shimada, S., & Abe, R. (2009). 观察竞争游戏时运动区域活动的调制。神经报告，20，979-983]。在本研究中，我们调查了镜像神经元系统的活动是否受到竞争游戏结果以及玩家和观察者之间空间关系的调节。当被试观看两人竞争游戏石头剪刀布（RPS）时，我们使用近红外光谱测量运动区域的活动。当被试执行 RPS 动作时被激活的一些运动区域的部分也在观察 RPS 游戏时被激活。有趣的是，这种活动的幅度（在观察时）取决于特定被试支持的玩家的结果和视角。在测量的运动区的背侧前区域中，当支持的玩家获胜而不是失败时，无论视角如何，活动都会显著增加。当玩家呈现出不一致的视角而不是一致的视角时，活动也会增加，无论结果如何。相比之下，只有当支持的玩家获胜并且观察到一致的视角时，运动区的背侧后区域才会被激活。我们认为，在观察竞争比赛时镜像神经元系统的活动反映了被试对观察到的玩家动作的内部同化。
