PSY 244 Chapter Notes - Chapter 5: Operant Conditioning, Retina, Visual Cortex
Document Summary
Sensation- the processing of basic information from the external world by the sensory receptors in the sense organs and the brain. Perception- the process of organizing and interpreting sensory information about the objects, events, and spatial layout of the world around us. 40-50% of our mature cerebral cortex is involved in visual processing. Newborns begin visually exploring the world minutes after leaving the womb: scanning the environment, pausing to look at a person or object, vision improves extremely rapidly in the first months. 1 month old looked primarily at the outer contour of the face and head, with a few fixations of the eyes. 2 month old fixated primarily on the internal features of the face, especially the eyes and mouth. 6 month olds can tell the difference as easily as they can between humans. Supported by evidence of perceptual constancy in newborns and very young infants: object segregation- the perception of the boundaries between objects.
