A study examined whether a correlation existed between mood ratings and subsequent display of problem behavior in eight adults with mental retardation. Results indicated that bad mood ratings were highly predictive of problem behavior. When an induction procedure to improve mood ratings was implemented, dramatic decreases in problem behaviors…

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)

The article reviewed research on professionals', consumers', and others' judgments of the restrictiveness, social acceptability, and estimated frequency of use of procedures to decrease problem behaviors of disabled persons. Most respondents agreed that more restrictive procedures should be used as a last resort and that less restrictive…

Fourteen students, aged 7-24, with severe developmental disabilities who exhibited frequent aggression, self-injury, and/or tantrums were assessed to engage in problem behavior maintained by social attention or by escape from unpleasant situations. The differential effectiveness of praise and time-out was measured, indicating the importance of…

Functional analysis of the self-injurious behavior (SIB) of three individuals with profound mental retardation indicated the behavior was maintained by negative reinforcement (escape from instructional situations). Stimulus fading was applied. Results indicated that instructional fading virtually eliminated SIB, but these effects were not…

Describes the evolution of Harper Alternative School, which serves disruptive, volatile, and seriously emotionally disturbed students who could not be managed within regular schools in Houston, TX. Through a process of constant change and refinement to meet students' needs, the school has developed a model that is successful in serving even the…

The Student-Assisted Functional Assessment Interview identifies antecedent events, ecological variables, and consequences that can be modified to improve a student's classroom behavior. The assessment tool solicits information directly from students about their preferences and their appropriate and inappropriate behaviors. Interview results can…

This article discusses using a group contingency as a technique to increase appropriate behavior and decrease inappropriate behavior of students with learning disabilities who are either in regular classrooms or special classes. The advantages and disadvantages of three types of group contingencies (dependent group contingency, independent group…

A forced-choice procedure was used with two children, ages three and seven, with profound mental retardation to identify reinforcers. Preferred stimuli were selected using approach responding and latency between stimulus presentation and the first occurrence of aberrant behavior (hand mouthing). Results indicated that latency may be useful in…

Individuals (n=55) with mild to moderate mental retardation rated the acceptability of differential reinforcement and time-out. Community-based subjects and institutionalized subjects differed in their ratings depending on the severity of the problem. (DB)

This article presents principles of behavior therapy that can be used alone to treat minor feeding problems in young children or in conjunction with other modalities to treat serious disorders. The article discusses assessment methods; variables in feeding, including time, space, child, feeder, food, and treatment; methods to increase or decrease…

A close friend and colleague of Burrhus Frederic Skinner comments on obituaries of Skinner published in major newspapers and expresses his gratefulness for Skinner's contributions to the field of behavioral psychology, including his writing of "The Behavior of Organisms" and development of teaching machines and programed instruction.…

The daughter of Burrhus Frederic Skinner writes of her father's activities during the last few days of his life--his speech upon receipt of an award from the American Psychological Association, his work on research papers and books, interviews, and his final admission to the hospital where he died.

The sleep-wake cycles of 4 developmentally delayed individuals (ages 3-19) with severe sleep disturbances were regulated using a faded bedtime procedure with response cost. Following treatment, all four increased their amounts of nighttime sleep; two decreased their excessive daytime sleep; and three decreased their night wakings. (Author/JDD)

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…
