Description

Description

This project will investigate the acquisition and generalized production of graphic symbol combinations in nonverbal children with autism who are using augmentative and alternative communication (AAC). About 50% of individuals with autism have severe speech and language disorders to an extent that they cannot meet their daily communication needs. These individuals are candidates for AAC intervention. AAC augments or replaces spoken language through alternative means such as graphic symbols or electronic devices. Previous research showed AAC users with autism were able to learn graphic symbols primarily for requesting, labeling, and rejecting. Their utterances, however, remained at the single-symbol stage, and little is known how to teach multiple-symbol utterances to this population. Moving from single- to multiple-symbol utterances and generalizing those productions is a critical step towards the emergence of syntax and generative language. Matrix training is an innovative approach for teaching multiple symbol combinations and their generalization. Matrix training uses linguistic elements (e.g., nouns, verbs, adjectives) presented in systematic combination matrices, and arranged to induce generalized rule-like behavior. This study applies a multiple probe design to assess learning and generalization of action-object combinations in five participants with nonverbal autism who will receive matrix training through an innovative iPad app.

Strategic Plan Objective

Strategic Plan Objective

Green dot: Objective has greater than or equal to the recommended funding. 4SG. Support at least five studies on interventions for nonverbal individuals with ASD by 2012. Such studies may include: o Projects examining service-provision models that enhance access to augmentative and alternative communication (AAC) supports in both classroom and adult service-provision settings, such as residential service-provision and the impact of such access on quality of life, communication, and behavior; o Studies of novel treatment approaches that facilitate communication skills in individuals who are nonverbal, including the components of effective AAC approaches for specific subpopulations of people with ASD; and o Studies assessing access and use of AAC for children and adults with ASD who have limited or partially limited speech and the impact on functional outcomes and quality of life. IACC Recommended Budget: $3,000,000 over 2 years.
