Document Summary
Girl with one hemispheres removed, in congenitally blind children visual areas used for reading braille: early life experiences can also change our genetic expression. A very impoverished environment can effect us when we our older: reflexes at birth, rooting reflex. Nursing reflex: palmar grasp reflex, plantar grasp reflex, learn to identify mom early on, critical periods, developmental stages during which children are able to acquire specific abilities, examples. Binocular disparity: related to ability to see in depth. If someone is born with a lazy eye or cross eyed, they will miss this critical period. How is this studied: use visually evoked potentials (vep) If the infant can see the stimulus, i will show up on the vep: mainly with being able to see the big picture. Developmental timeline: visual cortex and cones are still developing at birth, develop rapidly over first 6 months, adult levels reached within a year, depth perception.
