The study compared the effectiveness and efficiency of concurrent and isolation-intermix instruction in teaching four preschool children to read common words in their environment. Concurrent instruction resulted in students learning conditional discriminations in fewer trials and minutes of instructional time suggesting the value of teaching…

Six persons, ages 17-20, with moderate mental retardation were taught to identify 3 words by each of 2 different procedures--a fading procedure called the Task Demonstration Model and the Standard Prompting Hierarchy. The Task Demonstration Model produced fewer errors in acquisition, generalization, and maintenance. (Author/JDD)

The paper proposes teaching travel skills to developmentally disabled persons based upon the principles used to teach orientation and mobility to blind people. The approach emphasizes success orientation, sequencing, fading, individualized instruction, and in vivo instruction. Content includes environmental concepts, recovery techniques,…

Two time-delay conditions for teaching complex visual discriminations to 14 normal preschoolers, 12 with mild mental retardation, and 11 with moderate mental retardation were compared. Results indicated that for all populations and stimuli, time delay of multiple dynamic distinctive-feature prompts produced learning, while time delay of the single…

An adult worker with moderate mental retardation demonstrated substandard productivity in cleaning bathroom, hall, and office sites in a community-based competitive work setting. Productivity increased at each site following (1) videotape-based self-monitoring, and (2) distributed verbal feedback and breaks which were systematically reduced over…

Thirty-five students (age 5-21) with mental retardation completed a 10-lesson curriculum on verbal and signed vocabulary acquisition. Therapist only and therapist plus video methods resulted in higher spoken and manual sign production of targeted items compared to the video only method. Receptive vocabulary was not improved.

Four mentally retarded children (ages 4-11), 3 with autism, were successfully taught various adaptive behaviors for self-care skills. Training procedures involved the whole-task method and included modeling, verbal instructions, prompting, and edible and social reinforcement. (Author/JDD)
