to identify when in development and in what environments genetic influences on personality are activated and expressed. Early childhood and adolescence appears to be a time of relative genetic instability with genetic effects decaying in magnitude. Do direct, social pushes or constraints on patterns of behavior limit the ability of individuals to act according to their genetic predispositions as they develop? Or, do individuals increasingly respond to unique life experiences differently on the basis of their genotype? To resolve these questions, research will need to take into account not only environmental experience, but the unique reaction that each individual will have to different sorts of environments.
