Some students with intellectual disabilities require explicit instruction of language skills, including preposition use; however, little is known about effective ways to teach preposition use to this population. This study examined direct instruction (DI) to teach students to use and respond to prepositions. Results indicated that DI was an…

The study analyzed the effects of self-recording and behavioral skills training on guarding responses of 3 staff members while they assisted 3 students with multiple disabilities to ambulate. The intervention increased the percentage of correct posture and guarding responses and the distance that students ambulated. These effects generalized when…

Although delusional statements in people with intellectual disabilities and traumatic brain injury can be treated using behavioral interventions, none have demonstrated long-term treatment effects. In the current study, a functional analysis demonstrated that delusional statements were maintained by attention. Differential reinforcement of…

Results showed that the graduated prompting procedure was effective in training reach-grasp responding in all three children; for one child, effects were durable over repeated treatment applications, but not maintained during withdrawals; for another child, the procedure was effective in teaching reach-grasp responding in all three positions.…

This study assessed the validity of idiosyncratic choice-making behaviors of three children with multiple disabilities. Children were given either their "choice" of food or drink or were given the opposite. Direct observations of children's acceptance or refusal revealed the children consistently indicated choices during both conditions.…

Five students (13-18 years old) classified as profoundly/multiply handicapped were trained to use microswitches to indicate reinforcer preferences. When the microswitches activated the devices during training, a substantial increase in the duration of motoric responding occurred for all students. In addition, some students performed differentially…

Three experiments were conducted involving five people with profound multiple disabilities, to determine whether variations in alertness affected subsequent responsiveness to training programs. Findings suggest that existing levels of alertness do not indicate how individuals will respond during training and that alertness actually can be…

Four multiply handicapped students (aged 5-11) received skill instruction under four experimental conditions, involving differing teacher wait-times and intertrial interval durations. Student performance was superior under the long wait-time conditions irrespective of the length of the intertrial interval. (Author/JDD)

Four experiments involving 18 individuals (ages 14-55) with profound multiple handicaps found that 12 stimuli used in a preference assessment represented a comprehensive stimulus set for identifying preferences, though the utility of the set could sometimes be enhanced by caregiver opinion. Results also indicated that preferences identified were…

Measurement training had little general effect on either the behavior of two teachers or of their multihandicapped deaf students. However, after programing training, teachers increased their program writing and correct use of behavior modification procedures and generalized this training across pupils and target behaviors. (Author)

The applicability of two reinforcer assessment procedures to children with developmental disabilities and visual impairments was evaluated. Greater differentiation between stimuli occurred with a choice procedure than with a preference procedure. Measurement of compliance and responding rate in adaptive skill training confirmed that the choice…

We evaluated an enriched teaching program for reducing resistance and indices of unhappiness displayed by 3 individuals with profound multiple disabilities during teaching sessions. The program involved presentation of preferred activities before, during, and after each teaching session, discontinuation of identified nonpreferred activities, and a…

A choice assessment was used to categorize reinforcers as high, middle, and low preference with 4 males (ages 7 to 19) with multiple disabilities including severe/profound mental retardation. High-preference stimuli consistently functioned as reinforcers for all subjects whereas low-preference stimuli did not function as reinforcers. (Author/DB)

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…
