我们提出了第一个神经生理学的签名，显示出群体的社会背景和情感唤起对文化感知的独特影响，如宗教仪式的功效。使用一种新的协议，脑电图数据同时记录从中国少数民族的宗教信徒在团体和个人设置，因为他们认为低，中，高唤醒精神媒体仪式的视频剪辑呈现的效果。然后分析这些感知判断的神经振荡模式，分为低，中和高功效。结果揭示了不同实验条件下不同的神经信号和行为模式。唤醒水平预测仪式功效的评级。无论组或个体设置如何，疗效增加均以抑制α和β功率为标志。在组中，疗效评级趋于一致。个人设置显示增加参与者内的相位同步在α和β波段，而组设置增强参与者之间的θ相位同步。这反映了小组参与者倾向于共同的观点和社会协调。这些研究结果表明，共同存在的群体中，导致社会调谐效应的支持下，参与者之间的θ相位同步。这些神经同步模式共同揭示了集体仪式如何同时具有个人和集体维度。精神媒介仪式的情感性驱动个体对效能的感知，而群体中的共同存在则表明事件的重要性，并在感知评级中增强了社会一致性。换句话说，大规模集会可以促进社会凝聚力，而不一定需要直接面对面互动的群体规模限制。这可能对大型群体中同步性的可计算性以及符号互动主义等领域的人文研究产生影响。
We present the first neurophysiological signatures showing distinctive effects of group social context and emotional arousal on cultural perceptions, such as the efficacy of religious rituals. Using a novel protocol, EEG data were simultaneously recorded from ethnic Chinese religious believers in group and individual settings as they rated the perceived efficacy of low, medium, and high arousal spirit-medium rituals presented as video clips. Neural oscillatory patterns were then analyzed for these perceptual judgements, categorized as low, medium, and high efficacy. The results revealed distinct neural signatures and behavioral patterns between the experimental conditions. Arousal levels predicted ratings of ritual efficacy. Increased efficacy was marked by suppressed alpha and beta power, regardless of group or individual setting. In groups, efficacy ratings converged. Individual setting showed increased within-participant phase synchronization in alpha and beta bands, while group setting enhanced between-participant theta phase synchronization. This reflected group participants' orientation toward a common perspective and social coordination. These findings suggest that co-presence in groups leads to a social-tuning effect supported by between-participant theta phase synchrony. Together these neural synchrony patterns reveal how collective rituals have both individual and communal dimensions. The emotionality of spirit-medium rituals drives individual perceptions of efficacy, while co-presence in groups signals the significance of an event and socially tunes enhanced agreement in perceptual ratings. In other words, mass gatherings may foster social cohesion without necessarily requiring group-size scaling limitations of direct face-to-face interaction. This could have implications for the scaling computability of synchrony in large groups as well as for humanistic studies in areas such as symbolic interactionism.
