Developmental psychopathology is the study of the development of psychological disorders (e.g., psychopathy, autism, schizophrenia and depression) with a life course perspective. Researchers who work from this perspective emphasize how psychopathology can be understood as normal development gone awry. Developmental psychopathology focuses on both typical and atypical child development in an effort to identify genetic, environmental, and parenting factors that may influence the longitudinal trajectory of psychological well being.
