A reevaluation of a previous study which found a significant improvement in speechreading scores of 15 normal hearing adults following a word-scoring training intervention found that, though subjects increased verbal output and mean length of utterance, they did not improve sentence comprehension, syntactic correctness, or overall response…

The role of equivalence class formation in delayed position recognition span performance was examined with three mentally retarded adults. Matching-to-sample training established equivalence classes. In subsequent span tests, subject-produced numeral names led to dramatic increases in span scores. The equivalences provided precursors of verbal…

The study of 20 adult stutterers participating in a 32-hour program of fluency training found that results were consistent with the hypothesis that improvements in fluency during response-contingent stimulation may occur when stutterers access extant fluent speech that is not otherwise being fully utilized.

The engineering technique of motion study was evaluated as a means to identify efficient movements and improve the productivity rates for three severely retarded adults performing a mailing task. After receiving training on the most efficient movements, subjects improved production rates and maintained the improved rates. (DB)

The study with three blind and mentally retarded adults with additional disabilities found that general case simulation instruction in housekeeping skills led to generalization to untrained settings. Degree of generalization was inversely related to the severity and complexity of participant disability. (Author/DB)

Four methods for response prompting and fading are reviewed: increasing assistance, decreasing assistance, graduated guidance, and time delay. Comparative investigations involving these methods are discussed, and recommendations for practitioners and for future research are included. (Author/JDD)

Using an ABAB design, two procedures for requesting a change of activity were compared for their effect on the stereotypic behavior of a man with autism. One procedure requested immediate change of activities, whereas the second procedure gave advance notice of a change. Less stereotypy occurred when advance notice of change was given. (Author/DB)

The effects of a generalization training procedure on requesting by four adult subjects with Broca's aphasia were examined. Results revealed that generalization effects were greatest when trainers, as opposed to unfamiliar volunteers, served as conversational participants. Subjects' requests increased to a level comparable to a normal comparison…

Five adults with Prader-Willi syndrome (characterized by short stature, learning difficulties, incomplete sexual development, and uncontrollable eating) learned the conditional relations necessary for the formation of two equivalence classes under differential/nondifferential and edible/nonedible outcomes. Performance on test trials was better…

A procedure involving prompting, repetition of the correct response, and reinforcement was effectively used to teach three adults with profound mental retardation gestural yes-no responding. However, reliable generalization of the individuals' responses across settings or persons did not occur even after generality training. (Author/DB)

An adult male with mild mental retardation had previously been trained in a match-to-sample task on 16 arbitrary relations among 16 visual stimuli and 2 auditory stimuli. Testing indicated the development of 112 additional arbitrary relations that had never been reinforced. On two-year and three-year followup, his performances remained stable.…

The study's results showed that the self-instruction procedure used by four severely retarded adults led to improved vocational skills as indicated by increased work production rates and a concomitant decrease in the number of errors. (Author/DB)

The effectiveness of training procedures which used visual-visual arbitrary matching, blocked-trial matching-to-sample, and successive discrimination training to teach visual-visual discrimination of two-dimensional forms was evaluated with two men having severe mental retardation. Results indicated that the procedures did establish conditional…

This study compared selection of a preferred reinforcing stimulus just prior to a training session by either the trainer or subject with profound developmental disabilities. Results obtained with four adult subjects indicated little or no difference in reinforcement effects when reinforcing stimuli were selected by subjects rather than trainers.…

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)
