THE STUDY INVESTIGATED SOME OF THE RELATIONSHIPS BETWEEN A CHILD'S VERBAL BEHAVIOR AND ENVIRONMENTAL EVENTS NECESSARY IN ACQUIRING LANGUAGE. TWO TRAINABLE RETARDATES (FROM A GROUP OF SIX, AGED 3-6 TO 5) WITH A FUNCTIONAL VOCABULARY OF NO MORE THAN TWO OR THREE WORDS WERE SEEN INDIVIDUALLY IN 20- TO 30-MINUTE SESSIONS TWICE A WEEK DURING A 4-MONTH…

Four groups of moderately retarded 7- to 13-year-old children (N =4 in each group) were trained to respond to a triangle with apex up (S+) and not to a triangle with apex down (S-), with and without errors. (Author)

Four young adults with moderate mental retardation were taught to include "please" as part of requests, and four environmental stimuli present during training were assessed. Results indicated that presence of a single stimulus or pair of stimuli increased the probability of the "please" response, whereas presence of other…

The treatment appeared to be functionally related to significant reduction in the self-stimulatory behavior in the treatment setting. In addition, a functional relationship was indicated between treatment conditions in one setting and changes in behavior rates in two other nontreatment settings. (Author/DLS)

The efficacy of teaching higher level cognitive skills to the trainable mentally retarded is questioned as research has yet to show that the skills learned can be generalized by this population to the classroom or other settings. (Author/PHR)

Operant conditioning techniques were used to modify verbal behavior in 18 institutionalized, trainable mentally handicapped mongoloids with chronological ages from 4-6 to 7-10 and mental ages from 2.0 to 2.10. Two instruments were constructed to evaluate language: a language test and a speech rating scale. Project leaders had no prior knowledge of…

Following 4 weeks of unsuccessful conventional therapy, five trainable mentally retarded males (CA 7-12 years) were placed in a behavior modification group-therapy-readiness program (BMP). Immediate gratification, short range delayed gratification, and long range delayed gratification were used. Teachers were encouraged to continue the BMP in…

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).
