ABSTRACT
It is clearly the case that transactionalism—a theoretical stance that emphasizes the interdependence of factors contributing to development (Sameroff, 1983)—is the prevailing theoretical light being shed on the topic of developmental psychopathology, as reflected by the chapters presented in this volume as well as in attitudes expressed by the field at large. Nevertheless, it is still often heuristically useful to focus on some particular contribution to development and to elaborate on its key features. In this volume Plomin has chosen to focus on issues of heritability, Garber and Dodge on the role of cognitive schematas; I have chosen to selectively treat the issue of socialization processes.
