Children and the Physical Environment: Credo ReferenceBronfenbrenner's bioecological theory of child development provides the framework for this chapter. We present research that examines the role of the home environment in children's cognitive and socioemotional development. The child's experience in the home is a product of the child's abilities and personality, the opportunities to engage in meaningful interactions with objects and people in the home, and the physical characteristics of the home. It is this system, identified by Bronfenbrenner as a microsystem, of interactions that guide child development. Physical environmental attributes related to child developmental outcomes are crowding, privacy, noise, and housing quality.
