The nonhuman primate literature concludes that monkeys and apes do not exhibit handedness preferences at the population level. This discrepancy between human and nonhuman primate findings may be due to differences in the methods of assessment of handedness, lack of reliability between various measures of handedness, and a paucity of studies involving great apes. This paper presents the results of extensive hand preference studies with two language-trained chimpanzees (Pan troglodytes). Both naturalistic and experimental paradigms are described. In particular, various methodologic factors involved in handedness assessment, including the use of a hand preference measure previously used with human subjects were examined. Both chimpanzees exhibited a right-hand preference for fine motor tasks requiring manual dexterity.
非人类灵长类动物的文献表明，在群体水平上，猴子和猿类没有表现出用手偏好。人类和非人类灵长类动物研究结果之间的这种差异可能是由于用手偏好评估方法的不同、各种用手偏好测量方法之间缺乏可靠性，以及涉及大猩猩的研究较少。本文介绍了对两只接受过语言训练的黑猩猩（黑猩猩属）进行的广泛用手偏好研究的结果。描述了自然主义和实验范式。特别是，研究了用手偏好评估中涉及的各种方法学因素，包括使用先前用于人类受试者的用手偏好测量方法。两只黑猩猩在需要手部灵活性的精细运动任务中都表现出右手偏好。
