ABSTRACT
Throughout this introductory book, the uniqueness of developmental research has been emphasized in terms of its joint focus on change in antecedents and consequents and its concern with long-term historical linkages. Some of the related issues were discussed in detail; others, because of various constraints, received only cursory attention. We have attempted to foster recognition of the ultimate value of systematically developing research within a general orientation—as is provided, for example, by a focus on historical-developmental paradigms or the mechanistic and organismic models of humankind.
