General Processes of Development
Parents hold beliefs not only about specific aspects of their children’s development (the focus of most of the remaining chapters) but also about the general processes through which such developments come about. So, too, do developmental psychologists. This chapter addresses the fit between what parents believe and what psychologists have concluded, concentrating especially on two issues. The nature–nurture issue concerns the interplay of biological and environmental factors in the determination of development, including beliefs about the relative importance of the two forces and about particular environmental contributors, including parents. The continuity–discontinuity issue concerns the extent to which psychological functioning is characterized by consistency or change. As applied to development, the question is whether developmental change is a matter of incremental, quantitative change or whether qualitative change also occurs. As applied to children’s competencies and characteristics, the question is whether children’s behavior and the rules that govern it are consistent or variable across different tasks and different contexts.
