An individual's ability to respond to and align with the behavior of others is a fundamental component of social behavior. Zebra finches form lifelong monogamous pair bonds; however, zebra finches are also gregarious and can form strong social bonds with same-sex conspecifics. Here, we quantified behavior during brief 10-min reunions for males and females in five types of social conditions: monogamously bonded opposite-sex partners, familiar same-sex, familiar opposite-sex, novel same-sex, and novel opposite-sex dyads. We analyzed these interactions in three ways. First, we quantified overall activity levels (call and movement rates) for each individual. Second, we measured how coordinated calls and movements were by calculating (a) the percent difference in activity rates as an estimate of how similar calling and movement activity were between individuals within a dyad, and (b) the sliding correlation coefficients for time-stamped calls and movements for each dyad. Finally, we described multimodal behavioral profiles of coordination using principal component analyses. Overall, females were more active than males. For both females and males, activity levels as well as the coordination of calls and movements were significantly affected by social condition. In general, monogamous partners, female familiar same-sex dyads and familiar opposite-sex dyads were the most coordinated. This effect of familiarity shows that moment-to-moment behavioral coordination can be influenced by prior social experiences. Quantifying patterns of coordination or social synchrony may prove valuable for understanding the effects of social experience on brain and behavior.

熟悉会增强斑马雀科（Taeniopygia guttata）二元组在瞬间对行为的协调。

一个人对他人行为做出反应并与之保持一致的能力是社会行为的基本组成部分。斑马雀形成终身一夫一妻制的双键；但是，斑马雀也很合群，可以与同性异性结成牢固的社会纽带。在这里，我们量化了男性和女性在短暂的10分钟聚会中在五种类型的社会状况中的行为：一夫一妻制的同性伴侣，熟悉的同性伴侣，熟悉的对性伴侣，新颖的同性伴侣和新颖的异性双胞胎。我们以三种方式分析了这些相互作用。首先，我们量化了每个人的总体活动水平（通话和移动速度）。第二，我们通过计算（a）活动率的百分比差异来估算双联体中个体之间的相似通话和移动活动，以及（b）带时间戳的通话和每个二元组的运动。最后，我们使用主成分分析描述了协调的多峰行为模式。总体而言，女性比男性活跃。对于女性和男性，活动水平以及呼叫和动作的协调都受到社会状况的显着影响。通常，一夫一妻制伴侣，女性熟悉的同性双性恋和熟悉的异性双性恋是最协调的。熟悉的效果表明，从一开始到一刻之间的行为协调会受到先前的社会经验的影响。量化协调或社交同步模式可能被证明对于理解社交经验对大脑和行为的影响很有价值。（PsycINFO数据库记录（c）2019 APA，保留所有权利）。
