title: The search for functionality: the role of the environment in the development and maintenance of psychopathological symptoms.

Functional analysis is the empirical investigation of possible maintaining consequences for a specific target behavior. Case studies are used to illustrate how functional analysis may be used with individuals with developmental disabilities and possible mental illness.
