This study examined how reinforcer rate, quality, delay, and response effort combined to influence the choices of six adolescents with emotional disturbance and learning difficulties and the feasibility of an assessment methodology based on matching theory for determining differential responsiveness to reinforcer and response dimensions.

Two persons (ages 15-24) with developmental handicaps were taught by 2 therapists under varying punishment conditions. Results indicated that the task being taught was mastered by each subject only when the therapist delivering punishment was teaching and that each subject made more eye-to-face contact when the therapist delivering punishment was…

Three adolescents with severe mental retardation were trained to request snacks from visible three-item snack sets. During subsequent stimulus control assessment sessions, one subject requested food items when no food items were present, two frequently requested a missing item when the two other items were visible, and all subjects requested…

The effectiveness of a five-second time-delay procedure to teach three chained food preparation behaviors to four moderately retarded adolescents was evaluated within a multiple probe design across behaviors. The skills maintained over a three-month period and generalized from school to home for subjects completing the generalization probe…

This study found that, in a task context, differential reinforcement of other behavior (DRO) effectively reduced problem behavior and increased task performance of 2 adolescents with severe disabilities (ages 15 and 19), whereas a time-out procedure was ineffective. In a leisure context, time-out was effective while DRO was ineffective.…

A videotape modeling procedure used in conjunction with shopping training in one natural environment was effective with three autistic young adults in promoting generalization of purchasing skills to community stores. These and other results of the use of videotapes as a means of program generalization in community training programs are discussed.…

Three experiments, involving five students (aged 13-20) with profound, multiple handicaps, showed that the students could effectively use microswitches to demonstrate toy preferences, to indicate preferences for social attention, and to make specific requests of educational staff in school and community settings.

Four students, aged 15-19, with moderate mental retardation learned to cash checks and use an automatic teller through either a decreasing prompt hierarchy or time-delay procedure. Both strategies led to acquisition of target tasks and were equally effective in producing performance maintenance; however, the decreasing prompt hierarchy was more…
