Fourteen-month-old infants saw an object hidden inside a container and were removed from the disappearance locale for 24 hr. Upon their return, they searched correctly for the hidden object, demonstrating object permanence and long-term memory. Control infants who saw no disappearance did not search. In Experiment 2, infants returned to see the container either in the same or a different room. Performance by room-change infants dropped to baseline levels, suggesting that infant search for hidden objects is guided by numerical identity. Infants seek the individual object that disappeared, which exists in its original location, not in a different room. A new behavior, identity-verifying search, was discovered and quantified. Implications are drawn for memory, spatial understanding, object permanence, and object identity.
14个月大的婴儿看到一个物体藏在一个容器里，然后被带离消失地点24小时。当他们回来时，他们正确地寻找隐藏的物体，表现出客体永久性和长期记忆。没有看到物体消失的对照婴儿没有进行寻找。在实验2中，婴儿回来后在同一个房间或不同的房间里看到容器。换房间的婴儿的表现降至基线水平，这表明婴儿对隐藏物体的寻找是由数字同一性引导的。婴儿寻找消失的那个个体物体，它存在于原来的位置，而不是在另一个房间。一种新的行为，即身份验证搜索，被发现并进行了量化。文章对记忆、空间理解、客体永久性和物体同一性进行了探讨。
