The frequency of use of diagonal walking by three motorically immature vervet monkeys (Cercopithecus aethiops) is discussed. The subjects were housed at The Balcones Research Center (Austin, Texas) and ranged from 15-105 days of age. Mixed longitudinal data taken from film indicated that lateral walknig was the first gait employed by the infant vervets studied, but that diagonal walking completely replaced lateral walking by 81 days of age. These data were compared with those of captive infant Macaca mulatta, and feral infant Papio anubis. General agreement was found regarding onset and frequency of use of diagonal walking in the three genera.
讨论了 3 只运动能力不成熟的长尾猕猴（Cercopithecus aethiops）对角行走的使用频率。这些研究对象被安置在 The Balcones Research Center（德克萨斯州奥斯汀），年龄在 15-105 天之间。从影片中获得的混合纵向数据表明，横向行走是被研究的婴儿长尾猕猴首先采用的步态，但到 81 天时对角行走完全取代了横向行走。这些数据与圈养婴儿猕猴和野生婴儿狒狒的进行了比较。在这三个属中，对角行走的开始时间和使用频率普遍一致。
