Developmental psychopathology: Our welcoming, inclusive, and eclectic intellectual home.

The integrative nature of developmental psychopathology is its defining and most remarkable feature. Since its inception, often identified with the special issue of Child Development (Cichetti, 1984), this new discipline has shattered barriers and divisions that until then had artificially compartmentalized the study of human development, and perhaps even psychology in general, and it has proposed new ways of integrative thinking about development. One, developmental psychopathology has programmatically integrated research on typical or adaptive and atypical or maladaptive developmental processes and demonstrated how those inform each other. Two, developmental psychopathology has promoted bridges between developmental research and other disciplines. Three, less explicitly but equally importantly, developmental psychopathology has abolished conceptual and empirical barriers that had existed among various theories and perspectives within developmental psychology by creating a welcoming niche for research inspired by theories often historically seen as contradictory or incompatible. Ideas originating in psychoanalytic, learning, cognitive, ethological, and sociocultural theories all find a welcoming home and seamlessly coexist in heuristically productive harmony within developmental psychopathology, inform each other, and generate exciting questions and insights. This eclectic and conceptually inclusive nature is one reason for developmental psychopathology's lasting appeal and inspirational power.
