Capuchin infants (genus Cebus) are born in a behaviorally more altricial state than is known for infants of other primate taxa except apes. Development in the first 2 months after birth is characterized by the major reorganization of sleeping and waking, assumption of postural control and the appearance of prehension. Capuchins develop postural control, prehension and locomotion later than do squirrel monkeys, baboons or macaques, presenting a pattern of motor development intermediate between these relatively more precocial genera and apes. Capuchins provide a useful model primate system in which to study development and its links with behavioral variability and life history.
卷尾猴幼崽（僧面猴属）出生时的行为状态比除猿类之外的其他灵长类分类群的幼崽更为无助。出生后头两个月的发育特点是睡眠和觉醒模式的重大重组、姿势控制的形成以及抓握动作的出现。卷尾猴比松鼠猴、狒狒或猕猴发育出姿势控制、抓握和运动的时间更晚，呈现出一种介于这些相对早熟的分类群与猿类之间的运动发育模式。卷尾猴提供了一个有用的灵长类动物模型系统，可用于研究发育及其与行为变异性和生活史的联系。
