We investigated laterality in nipple preference in 16 mother-infant dyads, 8 bonobos, and 8 chimpanzees via an event sampling procedure in infants 5-55 mo of age. Both bonobo and chimpanzee infants preferred the left nipple, and the results were stable over time. Maternal age, experience, and rearing history did not influence laterality in offspring nipple preferences. We discuss the results in the context of the role of early mother-infant interactions on the development of laterality in primates.
我们通过事件抽样程序,对16对母婴、8只倭黑猩猩和8只黑猩猩进行了乳头偏好的偏侧性研究,这些婴儿的年龄在5至55个月之间。倭黑猩猩和黑猩猩婴儿都更喜欢左侧乳头,且结果随时间保持稳定。母亲的年龄、经验和养育史并未影响后代乳头偏好的偏侧性。我们在早期母婴互动对灵长类动物偏侧性发展的作用这一背景下讨论了研究结果。
