Document Summary
Processing basic information from the external world by the sensory receptors in the sense organs and brains. Organizing and interpreting sensory information about the objects, events, and spatial layout of the surrounding world. Humans rely on vision more heavily then most species: 40-50% of the cerebral cortex is involved in visual processing. Infants are shown 2 patterns or 2 objects at a time to see if they have preference for one over the other (whichever they look at longer) Infant is repeatedly presented with a given stimulus until the response declines. Infants initially have poor contrast sensitivity (ability to detect differences in light and dark areas), but this develops rapidly. Prefer faces that are judged by adults as attractive. Prefer mother"s face after just a few days. Prefer male. female faces depending upon who is their primary caregiver by a few months. Young infants are excellent at differentiating between human faces, and even good at differentiating non-human faces.
