Grooming between female chimpanzees and their offspring was studied in the Mahale Mountains, Tanzania. Infants under 2 years of age rarely groomed their mothers, and mostly groomed accessible parts of their mother's bodies, if they did so. Most older adolescents reciprocated grooming with their mothers almost equally. Daughters appeared to mature socially earlier than sons, judging from the earlier ages at which a female infant began to groom her mother, groom mutually with her, and groom others. Weaning infants groomed their mothers more when they were in oestrus than when they were not. Development of the use of grooming as a means of social manoeuvring is discussed.
在坦桑尼亚的马哈勒山脉对雌性黑猩猩及其后代之间的梳理行为进行了研究。2岁以下的婴儿很少为母亲梳理毛发，即便有梳理行为，也大多是梳理母亲身体上容易够到的部位。大多数年龄稍大的青少年与母亲相互梳理毛发的频率几乎相同。从雌性婴儿开始为母亲梳理毛发、与母亲相互梳理毛发以及为其他黑猩猩梳理毛发的年龄更早来看，女儿在社交方面似乎比儿子成熟得更早。处于断奶期的婴儿在母亲发情期时比不在发情期时更频繁地为母亲梳理毛发。文中还讨论了梳理行为作为一种社交手段的发展情况。
