This quasi-longitudinal descriptive case study evaluated problem behavior for an adolescent boy with developmental disabilities via repeated functional behavioral analysis (FBA) probes during a blinded cross-over from the atypical neuroleptic Risperdal (Risperidone) to Seroquel (Quetiapine). The repeated FBA probes showed no medication differences…

After finding that self-injurious behavior in two young males with developmental disabilities was negatively reinforced by escape from instructional activities, an intervention provided noncontingent escape on a fixed schedule and differential negative reinforcement of other behavior. Provision of escape, even when noncontingent, resulted in…

Three studies investigated environmental correlates of self-injurious behavior in seven developmentally disabled children and adolescents which were then later used for treatment. Correlates investigated included positive reinforcement, negative reinforcement, automatic reinforcement, and control. "Escape extinction" was successfully…

A study of an adolescent with severe mental retardation, who demonstrated self-injurious behavior (SIB) when given attention, evaluated the extent to which providing attention only to appropriate communication would reduce SIB. The client's SIB was reduced significantly only when the therapist left the room when he engaged in SIB. (CR)

A brief negative-reinforcement assessment was conducted with five children (ages 4 to 14) with developmental disabilities with severe destructive behavior. Children were trained to engage in an escape response and were presented with a variety of stimuli. For each child, several stimuli were identified that may serve as effective negative…

This study examined effects of restitution on object throwing behavior of an adolescent male with severe mental retardation. Restitution was shown to maintain throwing behavior. When the subject was not forced to pick up what he threw (no restitution), throwing dropped to zero and was maintained at a very low rate. (Author/PB)

Effects of extinction and negative reinforcement on latency of responses (including aggression and self-injurious behavior) following activity requests to an adolescent girl with mental retardation and autism were evaluated. Results showed that latencies occurred in a predictable order. The response class was expanded to include an appropriate…

A study found verbal reprimands, delivered contingent upon eating prohibited foods, were sufficient to decease the food stealing of a girl (age 14) with Prader-Willi syndrome. Warning stimuli were then successfully used to help her discriminate between permitted/prohibited foods during sessions in which food stealing was not directly observed.…

The use of paradoxical interventions and brief therapy interdictions with a population of emotionally disturbed adolescents (males and females ages 13-18) attending a semi-residential alternative school was investigated. Paradoxical interventions were made by the psychological staff for purposes of management and change of withdrawn, acting out…

Explores how theories concerning socialization mechanisms may be operationalized and tested. Provides a preliminary test of this strategy using 57 boys being treated for conduct problems. Results indicate that the role of both negative reinforcement and affect dysregulation play a part in the development of a child's antisocial behavior. (RJM)

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…
