A study of three children (ages 3-9) with severe problem behavior investigated alternatives to the typical application of noncontingent reinforcement (NCR) for problem behavior. Instead of using continuous access to reinforcers and extinction, the study found that an NCR schedule based on latency and NCR without extinction were more effective for…

Two children (ages four and five) with mild developmental delays and no appropriate toy play were trained individually on one topography for each toy. Previously reinforced topographies of toy play were then placed on extinction, resulting in the induction of untrained topographies. (Author/DB)

A study compared the effects of extinction (EXT) and fixed-time (FT) schedules as treatment for the severe problem behaviors of three individuals with developmental disabilities. During EXT, the reinforcer maintaining problem behavior was withheld. During FT, the reinforcers were presented response independently at preset intervals. FT schedules…

Functional communication training, extinction, and response chaining decreased escape-maintained aberrant behavior and increased task participation of 3 youth, ages 10 through 15, with moderate mental retardation, 2 of whom also had autism. Task escape was contingent on verbally responding and completing task steps. Behavior chaining also…

A behavioral consultation approach was effectively used to reduce problem behaviors in 2 field studies with 3 students (ages 10-14) having severe or profound mental retardation and their teachers. Intervention involved extinction of inappropriate behaviors, reinforcement of appropriate play behaviors, and teaching verbal skills functionally…

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…
