Children diagnosed with autism spectrum disorder (ASD) typically exhibit a range of social communication deficits. Presequenced stimulus arrangements, such as matrix training, can be used to facilitate generative responding. Accordingly, training procedures can lead to the acquisition of a greater number of targets that are not taught explicitly, with fewer learning trials. Matrix training provides a useful framework for selecting teaching targets to promote the emergence of untaught skills. Participants were 3 young boys diagnosed with ASD, who were taught noun-verb combinations of play actions as tact and listener responses. All participants learned the taught noun-verb targets and showed varying degrees of recombinative generalization to untaught targets. Across subsequent matrices, the rate of acquisition of new targets and the number acquired without direct teaching increased (i.e., recombinative generalization). This suggests matrix training stimulus arrangements can facilitate the acquisition of novel targets by teaching young children with ASD to recombine language components appropriately.
We evaluated a method for teaching children with autism spectrum disorder to respond to tactile stimulation of multiple body parts. Various objects (e.g., hairbrush) produced the sensations (e.g., prickly). In a multiple baseline design across participants, participants learned 9 sensation body part tacts and the evaluation concluded with tests of generalization to 3 novel body parts, 6 novel objects, and 3 novel sensations. Participants demonstrated generalization to novel objects, and to a lesser extent, novel body parts, but did not generalize tacts to novel sensations. These findings are discussed in terms of implications for teaching children with autism to tact sensations.
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.
