棉顶狨猴（Saguinus oedipus）选择的手杖位置可以使直接向内的拉力使食物触手可及（M. D. Hauser，1997）。狨猴无法用其他位置的手杖取回食物，而且它们也没有重新放置这些手杖。在这项研究中，簇绒卷尾猴（Cebus apella）更喜欢在存在手杖时可以直接拉动手杖，但它们也会以不同的方式重新定位手杖，并且随着练习，它们使用重新定位的手杖获取食物的成功率有所提高。根据生态心理学的预测，卷尾猴通过对这些物体的探索行为发现了手杖的可供性，而狨猴却没有。生态理论根据物种典型的操纵活动预测了这些差异，为研究工具使用行为的物种差异提供了有用的方法。
Cotton-top tamarins (Saguinus oedipus) selected canes positioned so that a straight inward pull brought food within reach (M. D. Hauser, 1997). Tamarins failed to retrieve food with canes in other positions, and they did not reposition these canes. In this study, tufted capuchin monkeys (Cebus apella) preferred canes they could pull straight in when these were present, but they also repositioned canes in individually variable ways, and their success at obtaining food with repositioned canes improved with practice. In accord with predictions drawn from ecological psychology, capuchins discovered affordances of canes through exploratory actions with these objects, whereas tamarins did not. Ecological theory predicts these differences on the basis of species-typical manipulative activity, and it provides a useful approach for the study of species differences in tool-using behavior.
