The relationship between preferred objects associated with stereotypy, stereotypic behavior, and accuracy of responding during a counting task by a child with autism was analyzed. Teaching with high-preference objects occasioned more stereotypic behavior and less accurate counting than teaching with medium- and low-preference objects. (Author/DB)

The diets of three individuals with profound mental retardation and histories of coprophagia (ingestion of feces) were supplemented with a nutritionally complete elemental diet called Vivonex, resulting in decreases in the frequency of coprophagia in all three cases. (DB)

The effects of two levels of exercise (walking versus jogging) in suppressing the self-stimulatory behavior during academic programming of a 5-year-old boy with autism were examined. Decreased physical self-stimulation and "out of seat" behavior were found only for the jogging condition. Sharp reductions in these behaviors did not return…

Level of spontaneous social initiating by three adult caregivers toward a youth with autism was studied during a program to increase the youth's level of social initiating. The youth's social initiations toward each adult were systematically reinforced. Frequency of spontaneous initiating toward the youth increased for each adult as the youth's…

A brief functional analysis indicated that the object mouthing of a young girl diagnosed with autism was maintained independent of social consequences. Separate and combined effects of response blocking and non-contingent reinforcement were then evaluated as treatments. Although both interventions were unsuccessful when implemented separately,…

This case study of a woman with profound mental retardation and a history of severe self-injurious behavior (SIB) found that the dramatic decrease in SIB following Naltrexone administration was maintained through placebo and no drug phases and at six-month follow-up. Findings are discussed in terms of endogenous opioid system theories of SIB. (DB)

A case study of a 25-year-old man with moderate mental retardation who engaged in self-injurious behavior included a functional analysis to determine the effects of the presence and absence of respite care. Results demonstrated a relationship between the presence of self-injury and the occurrence of respite care the previous evening. Altering the…

This case study focused on an adult with severe disabilities and multiple problem behaviors fitting a pattern of behavioral escalation. Functional assessment indicated that use of rule statements by the teacher was related to occurrence and escalation of problem behaviors. Elimination of rule statements was an effective instructional intervention…

The Verbal Interaction Analysis System is presented as an assessment of initial, dyadic conversations. Application of the VIAS to two case studies featuring mildly to moderately intellectually disabled adults shows how the VIAS provides an index of competence and assists in the development of specific treatment strategies. (Author/JDD)

The rate of self-injurious head hitting in an eight-year old with severe/profound mental retardation was reduced using contingent electric shock delivered via the Self Injurious Behavior Inhibiting System. An improved affective state and increased interaction with the environment were documented. Treatment gains were maintained at one-year…

A modified functional analysis was used to assess the behavioral function of a profoundly retarded man's self-injurious behavior (SIB). Differential reinforcement of alternative behavior effectively reduced SIB and related behavior problems, while compliance of a self-care acquisition task increased markedly. (Author/DB)

A function-based behavioral treatment package was developed for an 18-year-old male with mild mental retardation in a specialized inpatient unit for treatment of severe destructive behaviors associated with school refusal behavior. Treatment goals were achieved relatively quickly and follow-up data indicated treatment effects were durable.…

A multiple-baseline-across-subjects study found that training in self-management reduced the inappropriate verbalizations of two middle school students with learning disabilities in a special class setting. The students also progressed more rapidly through the classroom token-economy levels system, designed to improve academic and social skills…
