摘要

摘要在社交游戏等有风险的互动中,面部模仿等运动共振现象具有很强的适应性。在这里,我们研究了生活在动物园大型群落中的年轻猕猴(Macaca mulatta)在玩耍打斗过程中的快速面部模仿(RFM,即自动模仿玩伴的面部表情、玩耍表情)。我们首次发现 RFM 在幼年猕猴中高频率出现,这与之前对高度不耐专制的猕猴的研究结果截然不同,尤其是当触发者对回应者占优势时,以及当双方都是亚成年猕猴时。RFM的等级调节可能与玩伴等级越高,游戏的不确定性和风险性越大有关。这凸显了模仿在此类互动中改善交流和协调的重要性。有趣的是,RFM 延长了游戏时间,这可能表明对运动模式进行了更有效的微调。此外,RFM 的出现还能缩短游戏中断后重新开始游戏的延迟时间,这可能是保持玩伴兴奋的潜在动力。在研究旁观者是否能复制玩耍对象发出的玩耍表情时,我们没有发现 RFM,这突出表明直接参与互动可能是激活猴子 RFM 的关键。尽管进一步的比较研究应该调查RFM在容忍和不容忍专制的物种中的作用,但我们的发现为运动共振现象在专制社会中调节社会游戏的交流和适应价值提供了有价值的见解。意义陈述在涉及竞争和激烈身体接触的危险互动中,如打斗,复制伙伴的面部表情可以作为一种传达积极情绪和意图的策略。在这里,我们研究了快速面部模仿(RFM)在猕猴(Macaca mulatta)中的存在及其可能的作用。我们的研究首次证明,包括快速面部模仿(RFM)在内的交流策略在不耐受专制的猕猴物种中既存在又频繁出现。我们证明,模仿的作用不仅能延长嬉戏互动的时间,而且还与嬉戏唤醒的强化和/或传递有关。我们的研究表明了运动共振现象的适应价值是如何推动其进化的,以应对社会互动过程中的挑战。

Rapid facial mimicry as a regulator of play in a despotic macaque species

Rapid facial mimicry as a regulator of play in a despotic macaque species

Abstract

During risky interactions like social play, motor resonance phenomena such as facial mimicry can be highly adaptive. Here, we studied Rapid Facial Mimicry (RFM, the automatic mimicking of a playmate’s facial expression, play faces) during play fighting between young rhesus macaques (Macaca mulatta) living in a large zoo-housed group. For the first time and in contrast to previous data on highly despotic-intolerant macaques, we found RFM to be present at high frequency in young rhesus macaques, especially when the trigger was dominant over the responder and when both players were subadults. The hierarchical modulation of RFM may be associated with the increased uncertainty and riskiness of play involving a higher-ranking playmate. This highlights the importance of mimicry in improving communication and coordination during such interactions. Interestingly, RFM prolonged playful sessions, possibly indicating a more effective fine-tuning of motor patterns. Moreover, the occurrence of RFM had an effect on shortening the latency to restart playing after a break, possibly acting as an engine to potentially maintain playmates’ arousal. When investigating if bystanders could replicate play faces emitted by the playing subjects, we failed to find RFM, thus highlighting that being directly involved in the interaction might be crucial for RFM activation in monkeys. Even though further comparative studies should investigate the role of RFM across tolerant and despotic-intolerant species, our findings offer valuable insights into the communicative and adaptive value of motor resonance phenomena in regulating social play in despotic societies.

Significance statement

In risky interactions involving competition and vigorous physical contact, such as play fighting, replicating partners’ facial expressions can serve as a strategy to convey positive mood and intentions. Here we investigated the presence and possible roles of Rapid Facial Mimicry (RFM) in rhesus macaques (Macaca mulatta). For the first time, our study demonstrates that communicative strategies, including Rapid Facial Mimicry (RFM), can be both present and frequent in despotic-intolerant macaque species. We demonstrate that the role of mimicry not only prolongs playful interactions but can also be linked to the reinforcement and/or transmission of playful arousal. Our study shows how the adaptive value of motor resonance phenomena may have driven their evolution to cope with challenges during social interactions also for despotic-intolerant species.
