Principles of object perception (01 Jan 1990)
This article focuses on the capacities of human infants to perceive objects as unitary, bounded, and persisting bodies. Special attention is given to the problem of perceiving objects in natural visual arrays, in which most objects are partly hidden by, and adjacent to, the surfaces and objects that surround them, and in which objects enter and leave the field of view as they, or the observer, move. Drawing on experiments investigating infants' visual perception of adjacent and partly occluded objects, infants' haptic perception of the objects, and infants' apprehension of the persistence and identity of objects that move fully out of view, Spelke proposes that object perception results from an analysis of viewer-centered surface representations: an analysis that accords with a set of spatio-temporal principles that govern the behavior of all movable, solid bodies. The research reported in this article has markedly influenced thinking and subsequent research on the nature and development of object representations.
