在一项关于二元社交互动的实验中，我们邀请参与者在合作、竞争和“有趣的任务”条件下进行口头互动。我们关注互动者的情感与其非语言同步之间的联系，并探讨了哪些进一步的变量有助于情感：互动者的人格特质、性别和规定的互动任务。使用自动视频分析算法（运动能量分析），通过互动者身体运动的协调来量化非语言同步性。通过人格、依恋、互动风格、精神病理学和人际反应的标准问卷来评估特征。我们纳入了 168 名以前不认识的人，他们被随机分配到同性二人组中（84 名女性，84 名男性，平均年龄 27.8 岁）。两人从八个话题中选出四个大家普遍感兴趣的话题进行讨论，最后进行了有趣的互动。每次互动持续5分钟。在互动期间，参与者反复评估他们的影响。使用分层线性模型，我们发现同步发生的效果大小为中等至强，特别是在竞争性和有趣的任务条件下。积极情绪与同步性呈正相关，消极情绪与同步性呈负相关。至于因果方向，数据支持同步带来影响的解释，而不是反之亦然。非语言同步性和情感之间的联系在女性二人组中最强。这些发现扩展了之前关于关系中与情绪相关的同步和模仿的报道，并提出了同步影响相关性的可能机制。
In an experiment on dyadic social interaction, we invited participants to verbal interactions in cooperative, competitive, and ‘fun task’ conditions. We focused on the link between interactants’ affectivity and their nonverbal synchrony, and explored which further variables contributed to affectivity: interactants’ personality traits, sex, and the prescribed interaction tasks. Nonverbal synchrony was quantified by the coordination of interactants’ body movement, using an automated video-analysis algorithm (motion energy analysis). Traits were assessed with standard questionnaires of personality, attachment, interactional style, psychopathology, and interpersonal reactivity. We included 168 previously unacquainted individuals who were randomly allocated to same-sex dyads (84 females, 84 males, mean age 27.8 years). Dyads discussed four topics of general interest drawn from an urn of eight topics, and finally engaged in a fun interaction. Each interaction lasted 5 min. In between interactions, participants repeatedly assessed their affect. Using hierarchical linear modeling, we found moderate to strong effect sizes for synchrony to occur, especially in competitive and fun task conditions. Positive affect was associated positively with synchrony, negative affect was associated negatively. As for causal direction, data supported the interpretation that synchrony entailed affect rather than vice versa. The link between nonverbal synchrony and affect was strongest in female dyads. The findings extend previous reports of synchrony and mimicry associated with emotion in relationships and suggest a possible mechanism of the synchrony-affect correlation.
