AB - Two experiments examined infants' understanding of visible displacements at 9 and 12 months of age. The focus was on whether infants understand that the object has been deleted from its initial hiding place as part of its displacement to a new location. To evaluate this aspect of infants' understanding, displacement problems were compared with two-object problems on which separate objects were hidden at the first and second hiding place so that the initial object was not deleted from the first displacement location. Nondisplacement problems, on which the object remained at the first hiding place while the experimenter moved her visibly empty hand to the second place, were also included in the one-object condition. Although the results of the first experiment were equivocal, the second experiment provided clear evidence that even 9-month-olds have at least a limited sensitivity to the deletion component of displacements. In that experiment, the 9-month-olds searched significantly more at the second than at the first hiding place on displacement problems, and the distribution of their searches across the two visited locations on those problems was significantly different than on two-object problems. Although their performance was less consistent than that of 12-month-olds, there was no evidence that they suffered from any systematic misunderstanding that separated them from the older infants.
