Differential reinforcement of low rates of responding was used to reduce the disruptive behaviors of a blind 12-year-old boy with a learning disability. The subject earned reinforcers by not exceeding the established criterion of disruptive behaviors. An overall 88 percent reduction in target behaviors was observed across a 26-day period.…

This study attempted to operationalize, measure, and increase happiness among five adults with profound mental and physical disabilities. Happiness indices were defined and observed. Most preferred stimuli-produced increases in happiness indices, and practitioner ratings of participant happiness coincided with observed indices. Discussion focuses…

This study examined effects of providing attention (the presumed reinforcer) both noncontingently and contingent upon either self-injurious behavior or self-restraint with a 12-year-old female with multiple disabilities including profound mental retardation. Results were consistent with the hypothesis that both responses were maintained by…

The study found significant improvements in behavior when a profoundly mentally retarded blind subject was reinforced with music. The young woman also discriminated among different types of music, and behavior rates varied accordingly. (Author/DB)

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…

This study examined the relationship between the level of self-stimulation and the rate of correct task-related responses in 2 multiply disabled (severely retarded, deaf and visually impaired) individuals (ages 16 and 12). Findings suggested that self-stimulation does not always need to be suppressed to promote adaptive responding. (DB)

A functional analysis of eye poking by a four-year-old female with severe developmental disabilities and visual impairments showed that high rates occurred in all conditions. Attempts to identify the maintaining variable found that eye poking decreased only when finger-eye contact was interrupted by blocking the response. (Author/DB)

Evaluation of treatment acceptability was conducted with 78 staff members at a community-based residential facility for youth with severe behavior disorders and mental retardation, where the institutional treatment philosophy was explicitly behavioral. Unlike a previous study, in this setting acceptability ratings were not influenced by severity…

The response satiation model of instrumental performance was used in two experiments to establish contingencies which reduced the self-injurious behavior of two adults with profound mental retardation and multiple handicaps. Transfer and generalization of training effects were also observed. (Author/DB)

Three individuals with multiple severe disabilities were taught an appropriate response to problem behaviors, but the response was less efficient than the problem behavior on physical effort, schedule of reinforcement, or stimulus-reinforcer time delay. The response did not compete successfully with the problem behaviors until a new, more…
