Document Summary
Nature view: human enter the world with an inborn store of knowledge. Nurture view: knowledge is acquired through experiences and interactions with the world. Range of reaction: genetic makeup establishes range of possible developmental outcomes. Genotype-environment interaction: different characteristics result from different combinations of genes and environment. Behavior genetics: study of genetic and environmental bases of individual differences in behavior and personality. Heritability: statistical estimate of contribution of heredity to individual differences. Family studies: measure degree to which biological relatives share certain traits. Adoption studies: compare adopted children to adoptive families and biological families. Twin studies: compare pairs of monozygotic and same dizygotic twins. Dz twins share 50% of genes on average. Adoption twin studies: compare mz twins separated in infancy and mz twins reared apart. Evolutionary psychology: theory suggesting that psychological mechanisms in the past increased our ancestors" chances of survival and reproduction. Natural selection: behaviors and characteristics persist that contributed to survival and reproduction traits become more common.
