Document Summary

Orientation points: everything we experience comes through sensory apparatus at some time, the brain interprets the sensory input, the senses are well developed prenatally, sensory capacities are geared towards the social envornment, lifespan changes are not uniform. Nature/nurture: nature: senses appear to be innate or develop (mature) quickly, nurture: visual and auditory development require stimulation- all senses benefit from environmental embedded-ness, nativists: natural understanding at birth. Relatively universal patterns of decline in senses: empiricists: infant tabula rasa. Accumulation of evidence: infants seek the stimulation they need. Infants combine perception with action for exploration (sensory-motor or sensorimotor) Behavioral change (e. g. facial expression, sucking rate, orienting) Preferential looking: duration of looking at one stimulus pair. Habituation: learning to be bored: same thing over and over stimulus gets old. Operant conditioning: learning to react to one stimulus, discriminate stimulus. By the 6th month pc rods& cones on retina.
