生活在坦桑尼亚贡贝国家公园的 17 只 6 至 24 个月大的野生黑猩猩幼崽的社交互动受到哥哥姐姐的存在与否影响。对于有兄弟姐妹和没有兄弟姐妹的婴儿，花在社交互动（接触、梳理毛发和玩耍）上的总时间相似，与母亲的社交互动的总体水平也相似。然而，有兄弟姐妹的受试者与兄弟姐妹在一起的时间更多，而没有兄弟姐妹的受试者则与其他小组成员互动。这些结果表明婴儿黑猩猩社交互动的可能设定点。两组的发育变化也相似，但有兄弟姐妹的婴儿在 12-18 个月期间与母亲的互动程度较低，而与其他组成员的互动程度较高。社会行为水平与婴儿的性别无关。
The presence or absence of older siblings influenced the social interactions of 17 wild infant chimpanzees between the ages of 6 and 24 months living at the Gombe National Park, Tanzania. The total amount of time spent in social interaction (contact, grooming and play) was similar for infants with and without siblings, as was the overall level of social interaction with the mother. However, subjects with siblings spent more time with their siblings, while subjects with no siblings interacted with other group members. These results indicate a possible set-point for infant chimpanzee social interaction. Developmental changes were also similar in both groups, but the infants with siblings had lower levels of interaction with the mother and higher levels of interaction with other group members during the age period of 12-18 months. The levels of social behaviors were not related to the sex of the infant.
