interactionist view of intelligence

the view that intelligence always develops as an interaction between biological dispositions and environmental conditions and that it is difficult or impossible to separate the contributions of these two factors. Interactionists point out that genes always express themselves (manifest their effects in an individual) through a given set of environments and that the expression of the genes may be different as a function of the environment in which they are expressed.
