本实验的主要目的是研究先前报道的运动状态与第4阶段物体持久性表现之间的关系是否可以推广到其他物体定位任务的表现。第二个目的是评估视觉跟踪作为运动体验和搜索表现之间关系的中介变量的贡献。33周龄的婴儿（n = 20），爬行（n - 10）和爬行（n = 18）被测试使用一个搜索任务，在允许搜索之前，他们或隐藏容器被旋转180度。结果显示，婴儿移动后的运动状态与搜索性能有关，而与容器移动后的运动状态无关。此外，正确容器的视觉跟踪与运动状态无关，尽管它与搜索性能有关。这些发现表明，运动经验对婴儿搜索表现的影响是非常具体的，并且是由多种因素介导的，这些因素不一定在搜索任务中普遍存在。
The principal objective of this experiment was to investigate whether previous reports of a relation between locomotor status and stage 4 object permanence performance generalized to performance on a different object localization task. A secondary objective was to evaluate the contribution of visual tracking as a mediating variable in the relation between locomotor experience and search performance. Precrawling (n = 20), crawling (n - 10), and creeping (n = 18) infants (M = 33 weeks old) were tested using a search task in which either they or the hiding containers were rotated 180-degrees before search was permitted. The results revealed that locomotor status was related to search performance following a displacement of the infant, but not following a displacement of the containers. Moreover, visual tracking of the correct container was not related to locomotor status, even though it was related to search performance. These findings suggest that the effects of locomotor experience on infants' search performance are quite specific and are mediated by a variety of factors that do not necessarily generalize across search tasks.
