In the study reported on here, the authors used computer-based video instruction (CBVI) to teach 3 high school students with moderate or severe intellectual disabilities how to order in fast-food restaurants by using an augmentative, alternative communication device. The study employed a multiple probe design to institute CBVI as the only intervention tool and measured generalization of skills to community restaurants. For 2 of the 3 students, the ability to order their meals dramatically increased immediately following CBVI; for the third student, the ability to perform this task increased during a second generalization condition. Performance was maintained for each student. The authors discuss their results as support for this approach, which would be one solution for providing instruction in a simulated environment when community-based instruction is limited.
Task completion time was substantially decreased for two middle school students with a diagnosis of moderate mental retardation and autism spectrum disorder (ASD) following the presentation of high-preference items and choice via a computer-based video program. The study used an ABAB design to evaluate the effects of the program compared to tangible high-preference items presented in baseline. Students' time to complete three tasks decreased immediately following the introduction of the computer-based program. Results are discussed in terms of the advantages of this approach as one solution for providing novel and highly reinforcing activities to students with a diagnosis of ASD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
