一项针对恒河猴（猕猴）的人工搜索实验探索了隧道效应中的动态对象个性化：受试者观看柠檬滚下斜坡并在隧道后面休息（闭塞图1），然后观看猕猴桃出现并在屏幕后面的路径尽头被遮挡（闭塞图2）。当猕猴桃出现在柠檬应该出现的时间（如果它继续运动的话）时，受试者只在闭塞器2后面寻找食物——显然，在时空连续运动的基础上，他们认为柠檬已经变成了猕猴桃。相反，当柠檬的遮挡和猕猴桃的出现被短暂的停顿打断时，猴子们在两个遮挡物后面寻找食物。在进一步的控制条件下，本实验证明了在动态对应问题的背景下，对象持久性计算中的时空偏差-类似于成人视觉感知中的偏差。
A manual-search experiment with rhesus monkeys (Macaca mulatta) explored dynamic object individuation in the tunnel effect: Subjects watched as a lemon rolled down a ramp and came to rest behind a tunnel (Occluder 1) and then as a kiwifruit emerged and became occluded at the end of its path behind a screen (Occluder 2). When the kiwifruit emerged at about the time that the lemon should have (had it continued its motion), subjects searched for food only behind Occluder 2-apparently perceiving the lemon to have transformed into a kiwifruit on the basis of spatiotemporally continuous motion. In contrast, when a brief pause interrupted the occlusion of the lemon and the emergence of the kiwifruit, monkeys searched for food behind both occluders. With further control conditions, this experiment demonstrates a spatiotemporal bias-similar to a bias found in adult visual perception-in the computation of object persistence in the context of a dynamic correspondence problem.
