家猫(Fells Silvestris Catus)正迅速成为世界上最受欢迎的动物伴侣。众所周知，在驯化过程中发生的进化过程对物种的形态、行为、认知和交流能力有广泛的影响。由于面部表情是人类交流的中心，猫的面部表情可能在驯化过程中受到了选择。然而，目前还缺乏研究猫咪面部表情的标准化测量技术。在这里，作为使猫面部表情能够以基于解剖和客观的方式进行研究的第一步，猫面部动作编码系统(CatFACS)被开发出来。在家猫中确定了15个单独的面部动作(动作单位)、6个杂项动作(动作描述符)和7个耳朵动作描述符。然后，在收养收容所的环境中，应用CatFACS来调查猫的面部表情对人类偏好的影响。从猫咪收容所返回家园的速度被用作人类选择压力的指标。在与实验者的标准化接触中，准备在三个不同收容所收养的106只猫的行为被记录下来。这个实验设置旨在模拟一只猫和一个潜在的领养者，即一个陌生的人类的第一次相遇。每个视频的编码都是为了接近实验者、身体动作、尾巴动作和面部动作。猫咪的面部动作与归巢速度无关，这表明猫咪的面部表情可能没有经历过显著的选择。相反，摩擦频率与归巢速度呈正相关。研究结果表明，在家猫身上，人类更受公开的亲社会行为的影响，而不是微妙的面部表情。(C)2017爱思唯尔B.V.保留所有权利。
The domestic cat (Fells silvestris catus) is quickly becoming the most popular animal companion in the world. The evolutionary processes that occur during domestication are known to have wide effects on the morphology, behaviour, cognition and communicative abilities of a species. Since facial expression is central to human communication, it is possible that cat facial expression has been subjected to selection during domestication. Standardised measurement techniques to study cat facial expression are, however, currently lacking. Here, as a first step to enable cat facial expression to be studied in an anatomically based and objective way, CatFACS (Cat Facial Action Coding System) was developed. Fifteen individual facial movements (Action Units), six miscellaneous movements (Action Descriptors) and seven Ear Action Descriptors were identified in the domestic cat. CatFACS was then applied to investigate the impact of cat facial expression on human preferences in an adoption shelter setting. Rehoming speed from cat shelters was used as a proxy for human selective pressure. The behaviour of 106 cats ready for adoption in three different shelters was recorded during a standardised encounter with an experimenter. This experimental setup aimed to mimic the first encounter of a cat with a potential adopter, i.e. an unfamiliar human. Each video was coded for proximity to the experimenter, body movements, tail movements and face movements. Cat facial movements were not related to rehoming speed, suggesting that cat facial expression may not have undergone significant selection. In contrast, rubbing frequency was positively related to rehoming speed. The findings suggest that humans are more influenced by overt prosocial behaviours than subtle facial expression in domestic cats. (C) 2017 Elsevier B.V. All rights reserved.
