What factors influence how accurately we express our personalities? Here, we investigated the role of targets’ nonverbal expressivity or the intrapersonal coordination between head and body movements. To do so, using a novel movement quantification method, we examined whether variability in a person’s behavioral coordination was related to how accurately their personality was perceived by naive observers. Targets who exhibited greater variability in intrapersonal behavior coordination, indicating more expressive behavior, were perceived more accurately on high observability personality items, such as how energetic and helpful they are. Moreover, these associations held controlling for other indicators of overall movement, self- and perceiver-rated extroversion, as well as how engaging and likable targets were perceived to be. This provides preliminary evidence that variability in intrapersonal behavioral coordination may be a unique behavioral indicator of expressive accuracy, although further research that replicates these findings and examines the causal associations is needed.

哪些因素会影响我们表达个性的准确程度？在这里，我们调查了目标的非语言表达或头部和身体运动之间的内在协调的作用。为此，我们使用一种新颖的运动量化方法，检查了一个人行为协调的可变性是否与天真的观察者对其个性的准确程度有关。在人际行为协调方面表现出更大可变性的目标，表明行为更具表现力，在高可观察性人格项目上被更准确地感知，例如他们的精力充沛和乐于助人。此外，这些关联控制着整体运动的其他指标、自我和感知者评价的外向性，以及人们对目标的吸引力和可爱程度。
