Dynamic Assessment Of Aac Verb Symbols For Children With Autism Spectrum Disorder, Valerie Prieto, Cindy Gevarter, Cathy Binger, Mary Hartley

Speech and Hearing Sciences ETDs

This study used dynamic assessment (DA) with graduated prompting to evaluate whether preschool-aged children with autism spectrum disorder (ASD) demonstrated learning potential with verb-based augmentative alternative communication (AAC) symbols. Four participants completed DA sessions across three instructional conditions: (a) requesting actions embedded in play, (b) labeling actions embedded in play, and (c) labeling actions presented via video. Performance across these conditions along with a control condition was compared using an adapted multielement single-case design. Three participants demonstrated learning in at least two instructional conditions, and only one showed progress in the control condition. Overall, participants initially required less cueing to …

Light And Heavy Verb Productions Between Single And Sequential Picture Description Tasks In People With And Without Non-Fluent Aphasia, Jessica Hall

Honors Theses

Background: Previous research has shown that persons with non-fluent aphasia (PWNFA) suffer from the inability to retrieve words, specifically more of a difficulty with verb productions. Various discourse elicitation tasks have shown to have differing effects on verb retrievals in this population. However, there is a lack of research on the relationship between single vs. sequential picture description tasks and the productions of heavy and light verbs in persons with non-fluent aphasia.

Purpose: The purpose of this study was to analyze the ratios of heavy and light verbs produced in both single picture description tasks and sequential picture description tasks …

Word-Retrieval Treatment In Aphasia: Effects Of Sentence Context, Anastasia Raymer, Francine Kohen

Communication Disorders & Special Education Faculty Publications

Word-retrieval treatment studies in aphasia have reported the greatest influences on picture naming for trained words. To increase treatment effects to untrained words and sentence contexts, we investigated a sentence-reading treatment hierarchy that moves from errorless to generative production of sentences incorporating target nouns and verbs. In an individual with nonfluent aphasia, treatment resulted in improved picture naming for nouns and verbs and generalized increases in numbers of grammatical sentences and content words following noun therapy. A second individual with fluent aphasia improved little in picture-naming and sentence-generation tasks for both nouns and verbs. This sentence-based word-retrieval training, in which …
