本研究的目的是评估 Ateles geoffroyi 手动偏侧的发生情况，特别是测试视觉和触觉控制对优先使用手的影响。 13 只蜘蛛猴接受了三种不同的伸手任务，并评估了手部偏好，每只动物至少伸手 100 次。在所有三项任务中，都发现在群体层面上使用左手存在显着的横向偏差。在视觉和触觉引导的到达任务中的表现在手动侧向的方向或程度方面没有差异。雄性和雌性在表现上没有显着差异，除了在任务允许的情况下雄性用嘴取食物的频率明显高于雌性之外。结果表明，蜘蛛猴的右半球可能专门用于视觉和触觉引导的接触。
The purpose of this study was to assess the occurrence of manual laterality in Ateles geoffroyi and in particular to test the influence of visual and tactual control on preferential hand use. Thirteen spider monkeys were presented with three different food-reaching tasks and assessed for hand preferences with a minimum of 100 reaches per animal. In all three tasks a significant lateral bias towards use of the left hand at the group level was found. Performance in visually and tactually guided reaching tasks did not differ with regard to direction or degree of manual laterality. Males and females showed no significant differences in performance with the exception that males used their mouths to retrieve food when the task permitted, significantly more often than females. The results suggest a possible right-hemisphere specialization in the spider monkey for both visually and tactually guided reaching.
