nature–nurture
the dispute over the relative contributions of hereditary and constitutional factors (nature) and environmental factors (nurture) to the development of an individual. Nativists emphasize the role of heredity, whereas environmentalists emphasize sociocultural and ecological factors, including family attitudes, child-rearing practices, and economic status. Most scientists now accept that there is a close interaction between hereditary and environmental factors in the ontogeny of behavior (see epigenesis). Also called heredity–environment controversy; nature–nurture issue; nature–nurture problem.
