Theoretical perspectives on development derive from a wide variety of viewpoints. Although there are numerous important theoretical issues in development, three questions are central for most theories. The first of these is the so-called nature-nurture question, concerning whether most behavioral development derives from genetics or from the environment. The second of these issues is the role of children in their own development: Are children active contributors to their own development, or do they simply and passively react to the stimuli they encounter? Finally, there is the question of whether development is continuous or discontinuous: Does development proceed by a smooth accretion of knowledge and skills, or by stepwise, discrete developmental stages? Current perspectives within developmental psychology represent very different views on these issues.
Useful developmental theories must possess three properties. They must be parsimonious, or as simple as possible to fit the available facts. They must be heuristically useful, generating new research and new knowledge. Finally, they must be falsifiable, or testable: A theory that cannot be tested can never be shown to be right or wrong. Developmental theories can be evaluated in terms of these three criteria.
