Children and adults often encounter counterintuitive claims that defy their perceptions. We examined factors that influence children's acceptance of such claims. Children ages 3-6 years were shown familiar objects (e.g., a rock), were asked to identify the objects, and were then told that each object was something else (e.g., that the rock…

The ability to track moving objects, a crucial skill for mature performance on everyday spatial tasks, has been hypothesized to require a specialized mechanism that may be available in infancy (i.e. indexes). Consistent with the idea of specialization, our previous work showed that object tracking was more impaired than a matched spatial memory…

An important characteristic of mature spatial cognition is the ability to encode spatial locations in terms of relations among landmarks as well as in terms of vectors that include distance and direction. In this study, we examined children's use of the relation "middle" to code the location of a hidden toy, using a procedure adapted…
