To investigate the relationship between manual skills and hand preference in 4 female Japanese monkeys (Macaca fuscata), the technique of concurrent investigation of manual skills and hand preference was introduced. 4 female Japanese monkeys were required to take food out of a pipe using the left hand and right hand alternately. The performance time and the number of deviations from alternate sequence were recorded as measure of manual skills and hand preference. In the result, the preferred hand was not always consistently the skillful one; however, only one subject tended to choose the more skillful hand in problem-solving, and another subject learned the alternate sequence of reaching. The performances of two subjects indicated discrimination of both hands in Japanese monkeys is possible.
为了研究4只雌性日本猕猴（食蟹猴）的手动技能与用手偏好之间的关系，引入了同时研究手动技能和用手偏好的技术。要求4只雌性日本猕猴交替使用左手和右手从管道中取出食物。记录完成任务的时间以及偏离交替顺序的次数，作为手动技能和用手偏好的衡量指标。结果显示，偏好的手并不总是技能更熟练的那只；然而，只有一只猕猴在解决问题时倾向于选择技能更熟练的手，另一只猕猴学会了交替伸手的顺序。两只猕猴的表现表明，日本猕猴能够区分两只手。
