研究人员对两组棕色卷尾猴（Cebus apella）进行了大约146小时的观察，特别注意了这一物种的面部表情。观察到七个具有仪式化展示特性的离散面部表情。根据动机、状态指示和社会功能标准，这些行为被分类如下：(1)张嘴露齿威胁，(2)张嘴断鸣-可能是防御性威胁，(3)张嘴尖叫-安抚，母亲恳求，(4)咧嘴笑-可能是安抚和安慰，(5)咂嘴-安慰，导致被动接触，(6)额头抬起-亲和，导致主动接触，(7)放松张嘴玩脸，可能是安抚。对与面部表情相关的意向运动和行为的研究强烈表明，这里研究的棕色卷尾猴向其他群体成员提供了准确的动机信息。与卷尾猴在形态上相似的面部表情也存在于许多种猿科动物中，尤其是猕猴和猕猴，它们在相似的社会环境中也有类似的表情。在Cebus、Macaca和Papio，仪式化的安抚手势的存在可能是饮食多样性和由此产生的食物空间分布的功能。
Two captive groups of the brown capuchin, Cebus apella, were observed for approximately 146 hours, with particular attention paid to the facial expressions of this species. Seven discrete facial expressions having the properties of ritualized displays were observed. These were classified as follows according to motivational, status indication, and social functional criteria: (I) Open Mouth Bared Teeth-threat, (2) Open Mouth Staccato Beep-probably defensive threat, (3) Bared Teeth Scream-appeasement, maternal solicitation, (4) Grin-probably appeasement and reassurance, (5) Lipsmacking-reassurance, leads to passive contact, (6) Forehead Raise-affinitive, leads to active contact, and (7) Relaxed Open Mouth-play face, possibly play reassurance. An examination of the intention movements and the behaviors temporally associated with the facial expressions strongly suggests the brown capuchins studied here are providing accurate motivational information to other group members. Facial expressions morphologically similar to those observed in capuchins are also given by many species of Ceropithecinae, especially Macaca and Papio, with similar expressions occurring in similar social contexts. The presence of ritualized appeasement gestures in Cebus, Macaca, and Papio may be a function of the diversity of diet and the resulting spatial distribution of food items.
