PSY 260 Lecture Notes - Lecture 3: Binocular Vision, Kangaroo Care, Visual Impairment
Document Summary
Sensation - occurs when a sensory system detects a stimulus. Babies attend to everything at first, they"re learning what"s important. Perception - the mental processing and interpretation of sensory information. Coding - facial responses, cries, head turns. Habituation - demonstrating signs of being used to and comfortable around a stimulus, signifies recognition. Already acute at birth, will turn head to sounds and can pinpoint sound sources very early. Hearing checked at hospitals in north america and europe for sake of early intervention. Kangaroo care works partially because of being able to hear heartbeat. Newborns are legally blind, have a 4 to 30 inch focus range. Babies start smiling die to perception at 2 months. Colors - newborns see dulled colors initially but have adult level perception of color by 4 months. Binocular vision develops between 2 and 4 months, improves depth perception. Holding babies helps them relax; even stroking an arm softly will reduce heart rate.
