本研究旨在探讨灵长类动物眨眼行为与其他因素之间的关系。我们对71种灵长类动物的141个个体进行了视频记录，并分析了眨眼率、眨眼持续时间和“孤立”眨眼率（即，眨眼而不动眼睛或头部）与活动节律、栖息地类型、群体大小和体型因素有关。结果表明，三种类型的眨眼措施和身体尺寸因素之间的密切关系。所有这些指标均随体重增加而增加。此外，即使在控制了体型因素后，白天活动的灵长类动物也比夜间活动的灵长类动物表现出更多的眨眼。最重要的发现是眨眼行为与社会因素之间的关系，例如，组大小。在白天活动的灵长类动物中，即使在控制了体型因素后，也只有眨眼率具有显著相关性。眨眼率随着组大小的增加而增加。在灵长类物种中，新皮层的扩展与群体大小密切相关，并被认为是社会脑假说的有力证据。我们的研究结果表明，自发眨眼已经获得了社会沟通的作用，类似于梳理，以适应复杂的社会生活在灵长类动物的进化。
The present study was performed to investigate the associations between eye-blink behaviors and various other factors in primates. We video-recorded 141 individuals across 71 primate species and analyzed the blink rate, blink duration, and “isolated” blink ratio (i.e., blinks without eye or head movement) in relation to activity rhythms, habitat types, group size, and body size factors. The results showed close relationships between three types of eye-blink measures and body size factors. All of these measures increased as a function of body weight. In addition, diurnal primates showed more blinks than nocturnal species even after controlling for body size factors. The most important findings were the relationships between eye-blink behaviors and social factors, e.g., group size. Among diurnal primates, only the blink rate was significantly correlated even after controlling for body size factors. The blink rate increased as the group size increased. Enlargement of the neocortex is strongly correlated with group size in primate species and considered strong evidence for the social brain hypothesis. Our results suggest that spontaneous eye-blinks have acquired a role in social communication, similar to grooming, to adapt to complex social living during primate evolution.
