摘 要: | 对偏好性行为的研究,有助于了解脑功能不对称性对行为的影响,而吸乳以及携抱偏好,同时也是母婴关系的重要组成部分.本研究对海南猕猴利手,母猴携抱偏好、婴猴吸乳偏好进行了研究.共记录63只个体利手,28对母婴中母猴携抱偏好,以及35对母婴的婴猴吸乳偏好.结果发现,虽然个体层面上,证实了利手、吸乳和携抱偏好的存在,但是群体水平上没有显示出统一的偏好方向.成年雄性偏向左利手,成年雌性偏向右利手.初产母猴可能存在左侧携抱的偏好.母猴的携抱偏好与婴猴的吸乳偏好不存在相关性.

Abstract: | The study of behavioral laterality can help us know more about the influence from the functional asymmetry of brain on behavior,while maternal cradling and infant nipple sucking preference are also important part of mother-infant relation.This study focused on the handedness,cradling and sucking preference of Hainan rhesus macaque.We recorded 63 individuals for handedness study,and 28mother-infant pairs for cradling preference and 35 pairs for infant sucking preference.We found that there was laterality on individual level,but not on group level for all three behaviors.Adult males tended to be left handed while adult females tended to be right handed.Primiparity females preferred to cradling infant on the left side.There was no significant correlation between mother cradling preference and infant nipple sucking preference. |
