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 …

The Effect Of Linguistic Context And Explicit Contrast On The Fast Mapping Of Verbs, Samantha L. Scripture

Doctoral Dissertations

In typical language acquisition, word learning is an induction problem. When word learners hear an unfamiliar word, they make assumptions about the possible referent and its meaning. For nouns, this is relatively easy as word learners can rely on perceptual and pragmatic cues. For verbs, these two cues are fleeting, and word learners require additional kinds of cues for their meaning to be acquired. Two cues that affect verb learning include linguistic context and contrastive information. The current study used a within group comparison to examine the effect of linguistic context (i.e., rich vs. sparse) and contrastive information (i.e., implicit …

Light And Heavy Verb Usage By People With Non-Fluent Aphasia, Chase Sophia Kozak

Honors Theses

The purpose of the study was to investigate the discourse elicitation task effect and whether it affects the production of verbs with different semantic weight (light verbs with vague semantic representations, e.g., ‘do’, or heavy verbs with specific semantic representations, e.g., ‘deliver’). Thirty people with non-fluent aphasia and twenty people without aphasia were included. The light and heavy verb ratios over the total number of verbs were calculated for two discourse elicitation tasks: sequential picture description and storytelling. The results for the healthy control group showed that they produced a significant higher heavy verb ratio in sequential picture description than …

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 …

The Use Of Differing Verb Types In The Oral Narratives Of School-Age Children, Allison Ann Switzer

Graduate Theses, Dissertations, and Problem Reports

The aim of this project was to examine the use of action, metacognitive, and metalinguistic verbs in narratives relative to age-related growth for children with typical language and their peers with a language-based disorder. While limited information is known about the use of these differing verb types, there is evidence to show that metacognitive and metalinguistic verbs are less salient than action verbs, and therefore have a longer trajectory of acquisition. The oral narratives of 84 typically developing students were coded for occurrences of action verbs, metacognitive verbs, and metalinguistic verbs to obtain a total use as well as to …

Argument Structure Effects In Action Verb Naming In Static And Dynamic Conditions, Dirk B. Den Ouden, Steve Fix, Todd B. Parrish, Cynthia K. Thompson

Faculty Publications

Argument structure, as in the participant roles entailed within the lexical representation of verbs, affects verb processing. Recent neuroimaging studies show that when verbs are heard or read, the posterior temporoparietal region shows increased activation for verbs with greater versus lesser argument structure complexity, usually bilaterally. In addition, patients with agrammatic aphasia show verb production deficits, graded based on argument structure complexity. In the present study, we used fMRI to examine the neural correlates of verb production in overt action naming conditions. In addition, we tested the differential effects of naming when verbs were presented dynamically in video segments versus …

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 …
