为他人欢呼是一种常见的经历。欢呼可能会促进欢呼者与欢呼者的主观统一，可能涉及两个人大脑之间的同步活动。在当前的研究中，我们使用功能性近红外光谱法，在竞争性游戏中同时测量了玩家和观察者的感觉运动皮层活动。玩家与实验者进行石头剪刀布游戏，而观察者要么为玩家欢呼（欢呼组），要么判断玩家是否作弊（控制组）。与对照组相比，在欢呼组中，观察者报告说与球员的团结感明显更强，并且在观察球员获胜时表现出更大的感觉运动激活。在欢呼组中，运动员和观察员的感觉运动区之间的功能连接显著更大，表现出与运动员和观察员之间的主观统一感显著相关。这些结果表明，欢呼声增强了玩家和观察者内部状态的同步，建立了一种团结感。
Cheering for another person is a common experience. Cheering may facilitate the cheerer's subjective unity with the cheered‐for person, potentially involving synchronized activity between the two individuals’ brains. In the current study, we measured the sensorimotor cortical activity of a player and an observer simultaneously during a competitive game, using functional near‐infrared spectroscopy. The player performed the rock‐paper‐scissors game against an experimenter while the observer either cheered for that player (cheering group) or judged whether the player cheated or not (control group). In the cheering group, observers reported a significantly stronger sense of unity with the player, and exhibited greater sensorimotor activation when observing the player win, compared with the control group. The functional connectivity between the sensorimotor areas of the player and observer was significantly greater in the cheering group, exhibiting a significant correlation with the subjective sense of unity between the player and observer. These results suggest that cheering enhances the synchronization of the player's and the observer's internal states, establishing a sense of unity.
