This research examined lateral bias for rotational behavior in tufted capuchin monkeys (Cebus apella). A symmetrical distribution of rotational bias was noted, with approximately equal numbers of subjects preferring to turn to the right and to the left. As a group, adults did not exhibit a lateral rotational bias. Immatures preferentially rotated to the left. Across subjects, the strength of rotational bias was positively related to the incidence of right-eyed looking. Rotational bias was not related to hand preference. The finding of analogous age-dependent patterns of rotational bias in capuchins and in humans suggests that the rotational behavior of Cebus apella can be used to model an asymmetric response pattern that has been linked to development in Homo sapiens.
本研究考察了簇绒卷尾猴（僧帽猴）旋转行为的侧向偏好。研究发现旋转偏好呈对称分布，偏好向右转和向左转的受试者数量大致相等。作为一个群体，成年猴没有表现出侧向旋转偏好。未成年猴则优先向左旋转。在所有受试者中，旋转偏好的强度与右眼注视的发生率呈正相关。旋转偏好与用手偏好无关。卷尾猴和人类中存在类似的年龄依赖性旋转偏好模式，这一发现表明，僧帽猴的旋转行为可用于模拟一种与智人发育相关的不对称反应模式。
