Correlation between Heredity and Environment A child acquires his/her unique nature as the result of two causative factors. The initial factor is the result of the genetic structure inherited from his/her parents while the second factor consists of the influences experienced from daily socialization within the rearing environment. The three categorizations defined to describe the correlations between the child’s heredity and his/her environment are passive, evocative (or reactive) and active. In the majority cases parents impart their genes, their immediate environments and past experiences to their offspring. This observable fact is referred to as the passive gene environment correlation. An example supporting the passive heredity to environment correlation is the finding that being socially disadvantaged has a high correlation with low IQ levels. Alternatively, a child could inherit genes from his/her biological parents that predispose a very high IQ and the motivating influence of the family’s environment. This would encourage the child to excel, whatever the pursuit. Evocative correlations occur when the manner in which individuals respond to children is greatly influenced by the children’s own distinctiveness (Plomin, DeFries and Loehlin, 1977). For example, children with high IQs would draw a different response from their parents than children having low IQs. Active correlations are a result of the greater control exercised by children over their environments. For example children with lower IQ levels spend much less time involved in tasks that would enhance their intellectual development. Scarr and McCartney hypothesized that the role of passive, evocative, and active correlations shift in their significance in the course of development, with the passive correlation declining, the active correlation increasing and the
