Imitation problems are commonly reported in children with an autism spectrum disorder. However, it has not yet been determined whether imitation problems persist into young adulthood. In this study, we investigated imitation skills of 20 intellectually able young adults with autism spectrum disorder relative to 19 age-matched neurotypical adults. For this purpose, we used a bar-transport task, which evokes the application of the end-state comfort principle. Specifically, we examined whether young adults with autism spectrum disorder imitated the means-end structure of a demonstrator’s bar-transport action with and without application of the end-state comfort principle (imitation task). In addition, we examined whether participants spontaneously applied the end-state comfort principle during a similar bar-transport task (free execution task). Results revealed that young adults with autism spectrum disorder imitated the means-end structure of observed actions to the same degree as neurotypical adults ( p = 0.428). In contrast, they applied the end-state comfort principle less often during free executed actions ( p = 0.035). Moreover, during these actions, they were slower to place the bar into the penholder ( p = 0.023), which contributed to the reduced efficiency of their performance. Findings suggest that imitation abilities of young adults with autism spectrum disorder are preserved and that observing others’ actions might promote more efficient action planning in this population.

The authors of the current investigation developed and evaluated the effects of a tutoring system based on a small-group arrangement to two young adults with autism spectrum disorder on the acquisition, maintenance, and generalization of sight words. The tutoring system was comprised of a virtual teacher to instruct sight words, and a humanoid robot which adopted a peer metaphor, where its function was to act as an emulated peer. With the introduction of the robot peer (RP), the traditional dyadic interaction in tutoring systems was augmented to a novel triadic interaction in order to enrich the social content of the learning environment and to facilitate observational learning (OL). The virtual teacher implemented a constant time delay strategy to instruct three types of sight words: (a) target words exclusive to the participant, (b) target words common between the participant and the RP, and (c) nontarget words exclusive to the RP. In order to examine the efficacy of intervention, a multiple-probe design across three word sets, replicated across two participants, was utilized. Results indicated that both participants acquired, generalized, and maintained target words with 100% accuracy. Furthermore, the participants made fewer errors and required less instruction time to learn the words common between the participants and the RP. Finally, the participants acquired, through OL, the majority of words taught exclusively to the RP.

Despite legislation to improve post-school outcomes for young adults with autism spectrum disorder, they experience poorer employment outcomes than their peers without disabilities. Data indicate persons with ASD experience lower employment rates, earn less money, work fewer hours, are less engaged in their communities, and live independently less frequently than their peers without disabilities. Furthermore, the earnings of individuals with ASD lag behind earnings of their peers both with and without disabilities. In order to help improve employment outcomes for youth with ASD, this chapter describes the characteristics contributing to employment of individuals with ASD, the factors influencing employment of individuals with ASD, and the research related to evidence-based practices for young adults with ASD.
