人类幼儿在寻找与其他物体相互作用的隐藏物体时表现出惊人的失败，但成功地找到了不经历机械相互作用的隐藏物体。这种模式暗示了接触机械和时空知识之间的发展分离。最近的研究表明，成年非人类灵长类动物可能表现出类似的解离。在这里，我提供了第一个直接测试这种解离使用搜索范式与成年恒河猴。受试者观看一个李子在两个不透明的障碍物中的一个后面滚动。在实验1中，受试者必须根据阻挡李子运动轨迹的墙的位置来定位李子。受试者搜索错误，显然忽略了墙的位置信息。然而，在实验2-4中，当被试被给予关于李子运动的时空信息时，他们正确地搜索。结果表明，成年猴子使用时空信息，而不是接触机械信息，找到隐藏的对象。联系机械和时空知识之间的这种分离进行了讨论，根据发展理论的核心知识和文献的对象为基础的注意力在人类成年人。
Human toddlers demonstrate striking failures when searching for hidden objects that interact with other objects, yet successfully locate hidden objects that do not undergo mechanical interactions. This pattern hints at a developmental dissociation between contact-mechanical and spatiotemporal knowledge. Recent studies suggest that adult non-human primates may exhibit a similar dissociation. Here, I provide the first direct test of this dissociation using a search paradigm with adult rhesus monkeys. Subjects watched as a plum rolled behind one of two opaque barriers. In Experiment 1, subjects had to locate the plum based on the position of a wall that blocked the plum's trajectory. Subjects searched incorrectly, apparently neglecting information about the location of the wall. However, subjects searched correctly in Experiments 2-4 when they were given spatiotemporal information about the plum's movement. Results indicate that adult monkeys use spatiotemporal information, but not contact-mechanical information, to locate hidden objects. This dissociation between contact-mechanical and spatiotemporal knowledge is discussed in light of developmental theories of core knowledge and the literature on object-based attention in human adults.
