"...behavior geneticists have proposed a genes-drives-experience theory (Bouchard, Lykken, Tellegen, & McGue, 1996). As children mature they take an increasingly active and independent role in selecting, shaping, and interpreting their environments. Moreover, when given the opportunity, they select experiences more in line with their genetic proclivities. Each comes into the world with a different internal genetic compass, which causes them to be attracted to or repelled by different kinds of people, activities, and settings. The anxiety-prone will more often avoid anxiety-provoking situations; the emotionally stable will perceive the world as more benign than will the neurotic; and the musically gifted will more often seek opportunities to develop their talent (called active gene-environment correlation). People also create different environments for themselves by evoking different reactions from the people around them. The obnoxious will evoke more hostile social environments for themselves than will the amiable, and parents will appropriately provide different kinds of toys, support, and developmental opportunities to their children when they differ in needs, interests, and talents (called evocative or reactive gene-environment correlation). In addition, people differ genetically in their sensitivity to given external influences, such as particular pathogens or kinds of instruction (gene-environment interaction)."
