Document Summary
Lobe function/ frontal, temporal, and parietal (2: visual areas peak in synapse density within four months after birth, decreases to adult levels by age. 10: heavy growth in frontal lobes seen between 3 and 6 years gains in behavioral control, between 6 and 13 years, highest growth rate seen in temporal and parietal lobes. Role of experience (3: greenough and black 1999, experience-expectant development: universal activities, experience-dependent development: individual learning, effect of experience on brain depends on age. Neural plasticity (1: brain remains somewhat malleable until synapses pruned and committed to serving particular functions, plasticity greatest before age of two years; declines gradually into adolescence, with declining plasticity, sensitive periods also begin to close. Robert fantz used preferential-looking technique to show infants are capable of perceiving form and pattern. Acuity poor in first months but sufficient for infant"s tasks. Reaches 20/20 in second half of 1st year. Color vision relatively mature by 6 months.
