PSYC 1 Lecture Notes - Lecture 6: Grey Matter, Cerebral Cortex, White Matter
Document Summary
Lecture 6: culture, gender, & other environmental influences. 14 of 16 of this basic experiment: rats in the enriched environment developed more cerebral cortex (relative to the rest of the brain"s tissue) than those in the impoverished environment. Results influenced improvements in environments in animals and for children in institutions. White matter is composed of bundles of myelinated axons, which connect various gray matter areas (the locations of nerve cell bodies) of the brain to each other and carry nerve impulses between neurons. Society blames a host of negative child behaviors on bad mothering . The largest parenting effects occur at the extremes. In personality measures, shared environmental influences from prenatal development onward account for less than 10% of child differences. Peers the degree of peer influence is hard to trace. Apparent conformity could be a selection effect. Gardner (1998) concluded parents and peers are complementary.
