A longitudinal study of hand preferences was assessed in a sample of 53 captive chimpanzees. Four measures of laterality assessed during the first 3 months of life were correlated with three measures of hand preferences assessed when the subjects were between 2 and 5 years of age. In addition, the effect of rearing environment on juvenile hand preferences was assessed in a larger sample of 83 chimpanzees. Overall, some early asymmetries were predictive of juvenile hand preferences, notably head orientation and hand-to-hand activities, and a defensive grasping response. No significant effects of rearing on hand preferences were found but males were more right-handed than females for two of the three juvenile measures. The results are discussed within the context of different developmental models of hand preference in humans.
在一个由53只圈养黑猩猩组成的样本中进行了一项关于手偏好的纵向研究。在出生后的前3个月评估的四项偏侧性指标，与在受试者2至5岁时评估的三项手偏好指标相关。此外，在一个更大的由83只黑猩猩组成的样本中，评估了饲养环境对幼年黑猩猩手偏好的影响。总体而言，一些早期的不对称性能够预测幼年时的手偏好，特别是头部朝向、手对手的活动以及防御性抓握反应。未发现饲养对手偏好有显著影响，但在三项幼年指标中的两项上，雄性比雌性更倾向于使用右手。研究结果在人类手偏好的不同发展模型背景下进行了讨论。
