Document Summary
Nature view humans 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. Nature gives us a range of possibilities, nurture pushes us to either extreme of that range. Bigger the range, more available influence by the environment. Interactions between nature and nurture (genes and environment) Genotype-environment interaction different characteristics result from different combinations of genes and environment. Given the same genotype, the environment can cause different outcomes. Allergies to pollen only if they are exposed to a lot of pollen. If they have the genetic predisposition, and then are exposed to something, then they can develop a allergy to that thing. Antisocial personality only if they were mistreated as children. Behavioral genetics study of genetic bases of individual differences in behavior and personality. How much is determined by genes how much is determined by environment.
