Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan
Neural Activity Reveals Effects Of Aging On Inhibitory Processes During Word Retrieval, Ranjini Mohan
Open Access Dissertations
Word retrieval difficulties are one of the most frustrating problems in older adults. Poorer access to phonological (speech sound) representation of the target word has been postulated as the underlying deficit, supported by findings of improvement in word retrieval after phonological priming. But the great variability in naming performance among older adults may reflect cognitive scaffolding or compensatory neurophysiological processes related to maintenance or decline of naming abilities. In order better understand aging effects in the underlying neurophysiological changes associated with phonological retrieval, the present study examined electrophysiological correlates of phonological priming and word retrieval in adults across the lifespan. …
Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston
Perceptual Compensation In Individuals With Autism Spectrum Disorders, Elizabeth Anne Langston
Open Access Theses
Compensation for coarticulation is the extent in which an individual perceives the contextual variations of speech. When presented with an ambiguous consonant-vowel segment (e.g., a consonant halfway between /sa/ and /∫a/) research illustrates that a listener is likely to compensate for coarticulation with the following vowel. Therefore, a listener will be more likely to report an ambiguous speech sound as /s/ when it occurs before [u] than before [a]. Previous results have suggested that, within neurotypical individuals, the degree to which individuals compensate for coarticulation may be related to their Autism Quotient (AQ; Yu, 2010). However, this research did not …
Preschool Language And Phonological Proficiencies In Predicting Stuttering Recovery Or Persistence, Caroline E. Spencer
Preschool Language And Phonological Proficiencies In Predicting Stuttering Recovery Or Persistence, Caroline E. Spencer
Open Access Theses
The purpose of this study was to investigate the relationship between expressive and receptive language, phonological, and verbal working memory proficiencies in the preschool years and eventual recovery from or persistence in stuttering. Participants included 40 children who stutter (CWS). At ages 3-5 years, participants were administered the Test of Auditory Comprehension of Language, 3rd edition (TACL-3), the Structured Photographic Expressive Language Test, 3rd edition (SPELT-3), Bankson-Bernthal Test of Phonology--Consonant Inventory subtest (BBTOP--CI), Test of Auditory Perceptual Skills--Revised (TAPS--R) auditory number memory and auditory word memory subtests, and the Dollaghan & Campbell Nonword Repetition Test (NRT). Stuttering behaviors were tracked …
