Document Summary
Lecture 4 focused on chapter 5 development of senses. Sensation: the physical stimulation of the sense organs (ex. light reaching eye) Perception: the sorting out, interpretation, analysis, and integration of stimuli involving the sense organs and brain (processing it) Two theories of infant perception: 1) empiricist = emphasis on experience, the baby doesn"t really perceive anything (max of buzzing confusion , no specific stimulation) develops during infancy. Nativist = given what we know about infants, seems like they are born with the capacity to perceive things from the environment. We know that even prenatally, fetus can perceive diff types of stimulation. Production and migration of neurons and other processes occurs at diff rates: auditory and visual areas of cortex are first (first few months), then language areas (up to 1 year), then prefrontal cortex (for several years continues developing) Touch: well-developed at birth (reflexes - ex. rooting reflex turning head towards touch on face).
