Vulnerability Of Semantic Networks In Multiple Sclerosis: An Analysis Of Verbal Fluency Data, Sophia Lall May 2024

Vulnerability Of Semantic Networks In Multiple Sclerosis: An Analysis Of Verbal Fluency Data, Sophia Lall

Theses, Dissertations and Culminating Projects

Word finding difficulty is a frequently reported subjective cognitive concern among persons with Multiple Sclerosis (pwMS). Word-finding relies on several information retrieval processes, including search and retrieval from the conceptual store, the phonological store, the syllabary, as well as other stores of information. Neuropsychological assessments, including the semantic verbal fluency measure, can be used to measure word retrieval abilities. Despite this, the MS research literature shows that neuropsychological assessment of semantic verbal fluency yields mixed results in detecting word-finding difficulties. While some studies report finding statistically lower semantic fluency scores in pwMS relative to healthy controls (HC), others found no …


The Language Of Mechanical Support In Children: Is It ‘Sticking’, ‘Hanging’, Or Simply ‘On’?, Julia Marie Hauss May 2023

The Language Of Mechanical Support In Children: Is It ‘Sticking’, ‘Hanging’, Or Simply ‘On’?, Julia Marie Hauss

Theses, Dissertations and Culminating Projects

Research has found that children begin to differentiate in the terms they use to encode support. In English, BE on, the Basic Locative Construction (Levinson & Wilkins, 2006; “put on” in dynamic events) tends to encode support-from-below (e.g., cup on table), whereas lexical support verbs (e.g., hang, stick, tape, glue, etc.) tend to encode mechanical support. We see this differentiation in semantic space by six years of age (Johannes et al., 2016). Although this differentiation occurs, we can still use BE on to encode all types of support, just as we can use a variety of lexical verbs (e.g., the …


Finding The Means : The Bilingual Disparity In Semantic Context Use For Processing, Iyad Ghanim Jan 2022

Finding The Means : The Bilingual Disparity In Semantic Context Use For Processing, Iyad Ghanim

Theses, Dissertations and Culminating Projects

Early and late bilinguals both differ in the speed with which they comprehend language or in their processing of sentences compared to monolinguals. This is possibly a result of crosslanguage interference, differential allocation of cognitive resources, or some other difference in language-dependent processes. This dissertation presents research and review focusing on one such language dependent process — the use of sentential context and lexical-associative semantic information — to process sentences. In a series of studies, 34 bilinguals and 28 monolinguals complete a retroactive masked priming task, which provides an isolated measure of the use of semantic information to backwards recognize …
