The development and individual stability of three intimate social behaviors (Lipsmacking, Carrying Attempts, and Facial Inspection) were examined for 43 group-housed Cebus apella infants from birth to 2 years of age. Occurrence of these behaviors was scored from 10-min videotape samples recorded three times a week over that time. Frequency of Lipsmacking and Carrying Attempts by adult males, adult females, and juveniles were all highest in early months and decreased to low levels by the end of the first year. Facial Inspection of partners by infants, in contrast, first began at 3-4 months and increased over time, at least to adult males and juveniles. Correlational analyses indicated stable individual differences in these interactions with infants and outlined a relationship between these intimate behaviors and more general social patterns reported previously for these animals. Results suggest that adult males may play a special role in affording juveniles opportunities for social learning of foraging and manipulative skills.
对43只群居的白喉卷尾猴幼崽从出生到2岁期间的三种亲密社交行为（咂嘴、抱举尝试和面部检查）的发展及个体稳定性进行了研究。在这段时间内，每周三次从10分钟的录像样本中记录这些行为的发生情况并进行评分。成年雄性、成年雌性和幼年个体的咂嘴和抱举尝试频率在最初几个月均最高，到第一年末降至低水平。相比之下，幼崽对同伴的面部检查最初始于3至4个月，且随时间增加，至少针对成年雄性和幼年个体。相关分析表明，在与幼崽的这些互动中存在稳定的个体差异，并勾勒出这些亲密行为与先前报道的这些动物更一般社会模式之间的关系。结果表明，成年雄性可能在为幼年个体提供觅食和操作技能社会学习机会方面发挥特殊作用。
