Integrating Information Across Saccadic Eye Movements

1. Address correspor\dence to Paul Bloom, Department of Psychology, University of Arizona, Tucson, AZ 85721; e-mail: blooni@u. arizona.edu. 2. Not all object individuation is plausibly viewed as emerging from an innate object module. In particular, the identification of objects in a static scene draws on a person's prior experience with the objects and on sensitivity to cues such as discontinuities in color and texture. These are the same factors that apply for the individuation of nonobject entities such as parts, suggesting that the procedures for nonobject individuation can sometimes extend to objects as well. Note, however, that although infants are sensitive to object properties such as spatiotemporal continuity, the ability to exploit these other types of cues is not present early in development (for discussion, see Baillargeon &c Hanko-Summers, 1990; Spelke, Breinlinger, )acobson, & Phillips, 1993). This developmental dissociation suggests that although the two modes of individuation might sometimes apply to the same entities (objects), they are nonetheless distinct.
