In contrast to earlier notions, a systems view of an organism's development sees genes as only one component in a hierarchy of influences that produces finished traits and differentiation. Developmental canalization proceeds from genes, behavior, and environment as well as from the coaction of these factors. (BC)

Notes that psychologists' interest in behavioral development concerns individual differences in behavior. Explores complexities of genetic and environmental determination of development, and of canalization. Intelligence is considered as an example of the canalization of human behavior. (BC)

Maintains that (1) research questions must address intra- and extraorganism contextual relations and must be multidisciplinary in scope; (2) research must be sensitive to contextual variability and individual differences; and (3) scholars must develop empirically generative models linking the development of human beings with changing contexts.

This paper reviews research on disturbances of children with developmental delays and handicaps in responding to complex stimuli, suggesting that such disturbances may deleteriously influence behavioral/neurophysiological development. Intervention programs for teaching children with autism a generalized set to use in responding to complex…
