Psychology defines behavior as the study of how human beings learn observable responses, and the most influential components of behavior are the relative contributions of biology and experience, also classified as nature-nurture.

Pinker (2004) explored in his article “Why nature & nurture won’t go away” the influence of behavior genetics, which is the study of the relative power and limits of genetics and environmental influences on behavior, and the controversial issue of nature versus nurture. Though Pinker (2004) served nurture as soley an exemplum of environmental influence, i.e. every non-genetic influence, parenting and peers, cultural influences, and gender development, Myers (2007) focuses behavior as a product of a cascade of interactions between human genetic predispositions and surrounding environments. Nature and nurture both sculpt synapses, brain maturation provides an abundance of neural connections and experience preserves activated connections and allows those that are unused to degenerate.

Sights and smells, touches and tugs activate and strengthen some neural pathways while others weaken from disuse, putting forth the theory of nurture via nature, and stressing that early experiences, family and peer relationships, and all other experiences guide behavior development and contribute to individual diversity.

Pinker (2004) however pointed out that genes and environment are not always necessarily interlinked, he pointed out the following: Children exposed to a given language acquire it equally quickly regardless of their racial ancestry. Though people may be genetically predisposed to learn language, they are not genetically predisposed, even in part, to learn a particular language; the explanation for why people in different countries speak differently is 100 percent environmental.
