非人灵长类动物雌性携抱婴儿与婴儿吸乳偏好的研究进展

A Review on Maternal Cradling Laterality and Infant Nipple Preference in Non-human Primates

灵长类雌性动物在携抱婴儿时会表现出一种方向偏好,同时,婴儿在吸乳时也会表现出方向偏好。相关研究表明,这两类偏好与灵长类大脑不对称性及其功能的进化有着极其紧密的联系。此方面的研究作为灵长类偏好行为研究的重要关注点之一,在国外已得到了较好的发展,在国内尚处于萌芽阶段。由于多种影响因素的存在,非人灵长类已有的研究结果间存在一定差异。

Females have displayed laterality of cradling and carrying their babies, while babies have also showed their nipple preference in primates. Some studies have demonstrated that the preference for laterality in primates is physically based on the asymmetry of their brain and the functional evolution process. The maternal cradling laterality and infant nipple preference in primates is regarded as an important topic in the study field on primates. However, this topic has not gotten much attention in China, yet. The results that got from the studies oversea have showed a variation from species to species in non-human primates.
