A series of three experiments was conducted with three severely retarded children to investigate the vocalization-producing potential of two antecedent conditions: adult talk (commonly cited antecedent) and adult silence. (Author/CL)

Studies dealing with toilet training of severely/profoundly retarded persons are reviewed since the systematic operant approach of N. Azrin and R. Foxx in 1971. Replications are said to be few in number and equivocal in results, although modifications with retarded and nonretarded populations have produced informative and innovative approaches.…

The investigation sought to teach a sequence of arrival behaviors to a severely mentally retarded 12-year-old child living in an institution. Withdrawal and reintroduction of the pacing prompts established that increases in independent arrival behavior were attributed to the pacing prompts. (Author/SB)

This study found that, compared to measuring approach behaviors to a variety of stimuli, a forced-choice stimulus preference assessment used with four young children with severe mental retardation resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented…

Two adolescents with severe disabilities were successfully taught pictorial communication skills using an interrupted behavior sequence strategy. The independent variable involved insertion of a typical operant instructional trial for teaching communication skills into the midst of ongoing predictable sequences of behaviors, rather than at the…

Visual screening, a mildly aversive response suppression procedure in which the child's eyes are briefly covered, was evaluated across two studies for its effectiveness in reducing topographically similar and dissimilar stereotypic behaviors of four moderately or profoundly retarded children (aged 9 or 13 years).

Sixteen papers concerned with vocational habilitation of the severely and profoundly retarded are organized into three parts: issues in habilitation, stimulus control of vocational behavior, and instrumentation for program evaluation. Papers have the following titles and authors: "Structured Employment: Productivity and Productive Capacity" (R.…

The study examined the extent to which momentary DRO (differential reinforcement of other behavior) maintained suppression (following initial treatment with whole-interval DRO) of the maladaptive behavior of nine severely multihandicapped elementary aged students. Results indicated that momentary DRO maintained response suppression comparable to…

A severely disabled and retarded 15-year-old girl was examined for: effect of music and approval as reinforcers for following a command; effect of a food-pairing procedure on an approval alone condition, an approval plus music condition, and an ignore condition; durability of newly conditioned reinforcers; and strength of the new reinforcers as…

Two boys, ages 7 and 9, with severe developmental disabilities were taught to use requests conditionally (when desired items were proximally distant) to obtain desired snack items. Results suggest that the conditioned discriminations were established quickly and both learners generalized their conditional discriminations to other contexts.…
