This paper examined the association between grip type, hand use, and fingerprint patterns in a sample of captive chimpanzees. Grip type for simple reaching was assessed for the left and right hand and classified as thumb-index, middle-index, or single-digit responses. Fingerprint patterns were characterized as whorls, loops, or arches on each finger. The results indicated that chimpanzees exhibit significantly more thumb-index responses for the right compared to the left hand. In addition, thumb-index responses were more prevalent for subjects that had a whorl compared to a loop or arch on their thumb. The results suggest that fingerprint patterns are associated with individual differences in grasping type in chimpanzees as well as some variation in hand use.
本文研究了圈养黑猩猩样本中抓握类型、手部使用和指纹模式之间的关联。对左右手进行简单伸手抓握类型的评估，并将其分类为拇指-食指、中指-食指或单指反应。指纹模式被描述为每个手指上的涡纹、箕纹或弓形纹。结果表明，与左手相比，黑猩猩右手表现出显著更多的拇指-食指反应。此外，与拇指上有箕纹或弓形纹的个体相比，拇指上有涡纹的个体拇指-食指反应更为普遍。结果表明，指纹模式与黑猩猩抓握类型的个体差异以及手部使用的一些变化有关。
