PSY 244 Lecture Notes - Lecture 2: Categorical Perception, Syntactic Bootstrapping, Intersubjectivity
Document Summary
Perception of objects as being constant size, shape, color, in spite of physical difference in the retinal image of the object. Infant looks longer at the larger but farther away cube, researchers will conclude that the child has size constancy. Empiricists: all knowledge arises from experience, perception of constant size and shape of objects develops as a function of spatially experiencing our environment. Nativists: certain aspects of knowledge are hardwired, ex: perceptual regularity stems from inherent properties of the nervous system, view supported by evidence of newborn perceptual constancy. Object segregation: identification of separate objects in a visual array, perception of boundaries between objects, experimental findings. Infants (after habituation), like adults, assumed that there was a sing intact rod moving behind the block as evidenced by longer infant gaze at broken rod: common movement. Powerful perceptual cue leads infants to perceive disparate, unified moving elements as part of a unitary object: identification of separate objects in a visual array.
