Several studies have demonstrated that conditions can be arranged to promote increases in a nontargeted verbal operant following instruction of another verbal operant. In the current study, we used a multiple baseline design to evaluate the effects of 2 instructional protocols on nontargeted verbal repertoires (listing of synonyms and vocal…

The purpose of this experiment was to establish discriminative control of responding by an antecedent stimulus using differential punishment because the results of past studies on this topic have been mixed. Three adults with mental retardation who exhibited stereotypy not maintained by social consequences (i.e., automatic reinforcement)…

Sensitivity to reinforcement contingencies was examined in six individuals with mental retardation using a concurrent operants procedure in the context of a computer game. Results included individual differences in sensitivity and differential sensitivity to rate and magnitude variation. Results suggest that comprehensive assessments of potential…

The developmental pattern of present behavior modification programs for the adult mentally retarded is evaluated. (Author)

Results of a study comparing the outcome of a reinforcement (do only) procedure with correspondence (say/do) training indicated no apparent differences in generalization between two groups of mentally retarded adults (N=12). Rule-governed behavior, rather than verbal regulation of behavior, may best account for behavior changes seen in…

Social feedback was investigated as a treatment strategy for reducing inappropriate verbalizations by a retarded adult in a vocational-training program. Treatment procedures were introduced as a combination of three components: praise for not verbalizing inappropriately, reprimands, and instruction. (Author)

Described is an Operant Conditioning-Token Economy Program, teaching patients to be responsible for their own behavior, to make choices, and to be motivated to change. The program was instigated with mentally ill patients in a state hospital and was later used with institutionalized mentally handicapped groups. After two years, only four of the…

A profoundly retarded 28-year-old female was trained to avoid an aversive but harmless shock to the foot by withdrawing the foot upon presentation of a visual cue. (Author/SBH)

A survey of 55 Louisiana members of the American Association on Mental Retardation (AAMR) indicated disagreement with an AAMR position statement condemning inhumane forms of aversive therapy. AAMR is urged to reconsider its position concerning the scope of aversive therapy, need for further research, and use of aversive therapy with some…

Thirty college students and 30 moderately retarded persons averaging approximately equal age received eight alternating phases of acquisition and extinction trials with an electric pulse as the unconditioned stimulus for classical eyelid conditioning. (Author)

In two experiments involving a two-choice marble dropping game children responded more to social control than to the magnitude of the reward. (ST)

A food satiation procedure was used in two experiments to decelerate the frequency of vomiting responses in two profoundly retarded adults who exhibited well-defined vomiting-ruminatory response chains. (Author)
