CPSY 4343 Chapter Notes - Chapter 4: Subjective Constancy, Depth Perception, Face Perception
Document Summary
By 6 months, absolute thresholds are close to adults". Visual perception: pattern and face perception. Visual cortex shown to develop early, relative to other parts of the cortex. Generation of synapses begins around birth and reaches its peak around age 1. Fantz (1958)- visual patterns can be discriminated from an early age (a little less than 2 months) Newborns show preferences for faces over a control stimulus. Infants prefer to look at moderately complex visual stimuli with lots of boundaries and edges. As infants grow they scan visual stimuli more. By 6 months are similar to adults in face perception: perceptual constancies. Adults perceive the world using a variety of constancies. Constancies: the lack of change in perceptual interpretation as a stimulus undergoes objective change as a function of the viewer"s changing angle of vision. Shape constancy: the perception that an object retains its shape even when the observer"s angle of view with respect to that object changes.
