Humans show greater affiliation with people who are behaviorally synchronized with them but little is known about the impact of synchronization at an interspecific level. We, therefore, explored whether the synchronization of humans with dogs affects dogs' human preferences. Pet dogs were exposed to two unfamiliar persons: one synchronized her walking behavior with them and one walked randomly. In a preference test, molossoids exhibited a clear social preference for the synchronized person, unlike shepherds. We conclude that pet dogs show a greater affiliation with humans who mimic their walking behavior, although genetic selection modulates this propensity. Behavioral synchronization, therefore, acts as a social glue in dogs too. It is the first time that such a human-like ability has been highlighted in domesticated canids at an interspecific level. Implications for the evolution of behavioral synchronization are discussed.
人类与行为同步的人表现出更强的亲密感，但对于种间层面同步的影响却知之甚少。因此，我们探究了人与狗的同步是否会影响狗对人的偏好。宠物狗接触了两个不熟悉的人：一个人与它们同步行走，另一个人则随意行走。在偏好测试中，獒犬对同步行走的人表现出明显的社交偏好，而牧羊犬则不然。我们得出结论，宠物狗与模仿它们行走行为的人表现出更强的亲密感，尽管基因选择会调节这种倾向。因此，行为同步在狗身上也起到了社交粘合剂的作用。这是首次在种间层面上，在驯化的犬科动物中凸显出这种类似人类的能力。我们还讨论了行为同步进化的意义。
