Coprophagia, the ingestion of fecal matter, occurs among some individuals with developmental disabilities and is associated with a variety of health risks (e.g., diarrhea, intestinal parasites, blood-borne pathogens; Parry-Jones & Parry-Jones, 1992). Studies that have evaluated operant-based treatments of coprophagia have been limited by a lack of…

Stokes, Osnes, and Guevremont's (1987) implicit definition of correspondence classes is fundamentally procedural. A contingency-space analysis, on the other hand, is independent of specific procedures and focuses attention on problems inherent in some procedural definitions. It addresses the issue of distinguishing specific instances from classes.…

The use of operant procedures was extended to decrease immediate echolalia and increase appropriate responding to questions of a 21-year-old autistic man. Multiple baseline designs demonstrated that echolalia was rapidly replaced with correct stimulus-specific responses. A variety of generalized improvements were observed in verbal responses to…

Six behaviorally handicapped elementary students participated in short-term resource treatment to bring their behavior under the control of a combination of treatment procedures emphasizing self-evaluation. Results indicated that students maintained appropriate classroom behavior in their regular classrooms, once self-evaluation procedures were…

Dimensions characteristically descriptive of applied behavior analysis over the past 20 years are explored: applied, behavioral, analytic, conceptual, technological, effective, and capable of appropriately generalized outcomes. Effectiveness in the future must take into account cost-benefit ratios, social validity assessments, and the need for…

A brief training manual was developed to teach child-care workers to contingency contract with delinquent youths living in residential care facilities. Results from analogue training simulations and generalization tests indicated that workers became more proficient in contract negotiation and writing behaviors and were able to apply the skills.…

High-probability requests were provided to two boys (age seven) with behavior disorders and severe disabilities as an antecedent to delivering a low-probability request. Results showed an immediate increase in appropriate responding when the intervention was delivered. Generalized responding and response maintenance were also exhibited.…
