Document Summary
Psyc 1 textbook notes module 32: genetic and environmental influences on. Intelligence scores of identical twins raised together nearly as similar as same person taking the test twice. Heritability: proportion of variation among individuals that we can attribute to genes; may vary depending on the range of populations and environments studied. Identical twins" brains have similar gray and white matter volume, areas associated with verbal and spatial intelligence virtually the same; similar brain activity when doing mental tasks. Where environments vary widely, environmental differences are more predictive of. Adoption enhances intelligence scores of mistreated/neglected children/adopted from poverty into middle-class homes. Intelligence scores of unrelated siblings who were raised together correlate. Mental similarities between adopted children and adopted parents go up with age until they reach 0. Identical twins" similarities continue to increase over lifespan. Poor environmental conditions can depress cognitive development. Preschool programs, nutritional supplements to pregnant mothers and newborns, interactive reading programs increased intelligence.
