title: Towards a comprehensive model of stereotypy: integrating operant and neurobiological interpretations.
abstract: The predominant models on the emergence and maintenance of stereotypy in individuals with developmental disabilities are based on operant and neurobiological interpretations of the behavior. Although the proponents of the two models maintain largely independent lines of research, operant and neurobiological interpretations of stereotypy are not mutually exclusive. The paper reviews the two models of stereotypy and proposes an integrated model using recent findings on the neurobiology of reinforcement. The dopaminergic system and the basal ganglia are both involved in stereotypy and in reinforcement, which provides a potential link between the models. Implications of the integrated model for future research are discussed in terms of improving the assessment and treatment of stereotypy in individuals with developmental disabilities.
