Considerations in the analysis and treatment of dietary effects on behavior: a case study

Scientific and public interest in the effects of diet of behavior disorders has recently increased. This paper argues that (1) the experimental analysis of behavior offers an effective scientific methodology for assessing the effects of dietary substances on behavior problems, and that (2) such analysis permits behavioral consequences to be considered as an alternative treatment to dietary control. A case study of a 9-year-old retarded boy with autistic behaviors is presented. Suspected dietary substances were demonstrated to be effective influences on the child's behavior, whereas a simple behavior modification program improved his problem behaviors. Also discussed are issues and problems which arise in research on dietary effects on behavior and in selection of effective and ethical treatments.
