Indicators Of Mild Cognitive Impairment Associated With Language Processing And Production, Diana Julbe-Delgado Jun 2020

Indicators Of Mild Cognitive Impairment Associated With Language Processing And Production, Diana Julbe-Delgado

USF Tampa Graduate Theses and Dissertations

The research purpose of the present study was to (1) examine cognitive-linguistic features related to processing and production across a series of tasks that are representative of everyday discourse and (2) compare older adults with and without mild cognitive impairment (MCI) across linguistic features. Twenty-seven participants, including 12 individuals with- and 15 individuals without MCI, were enrolled from a larger study (Hudak et al., 2019). Cognitive status was initially assessed as part of the larger study using the Montreal Cognitive Assessment (MoCA; Nasreddine et al., 2005). Participants who scored ≤ 25 on the MoCA received a standardized neuropsychological evaluation and …


Factors Related To Hearing Aid Use Among Older Adults From Hispanic/Latino Backgrounds: Findings From The Hispanic Community Health Study/Study Of Latinos, Michelle L. Arnold Jul 2018

Factors Related To Hearing Aid Use Among Older Adults From Hispanic/Latino Backgrounds: Findings From The Hispanic Community Health Study/Study Of Latinos, Michelle L. Arnold

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation was to understand perceived hearing loss and hearing health care use among older adults from Hispanic/Latino backgrounds using the Andersen model of health care utilization as a framework. A cross sectional analysis of audiometric and survey data from the Hispanic Community Health Study/Study of Latinos was used to estimate factors that characterize perceived hearing handicap and hearing aid use, and to determine hearing aid use rates in a large group of older Hispanic/Latino adults. Data came from 6970 adults aged 45 to 76. Results revealed that self-perceived hearing handicap is significantly correlated to measured hearing …


Large Cross-Sectional Study Of Presbycusis Reveals Rapid Progressive Decline In Auditory Temporal Acuity, Erol J. Ozmeral, Ann C. Eddins, Robert Frisina Sr., David A. Eddins Jul 2016

Large Cross-Sectional Study Of Presbycusis Reveals Rapid Progressive Decline In Auditory Temporal Acuity, Erol J. Ozmeral, Ann C. Eddins, Robert Frisina Sr., David A. Eddins

The auditory system relies on extraordinarily precise timing cues for the accurate perception of speech, music, and object identification. Epidemiological research has documented the age-related progressive decline in hearing sensitivity that is known to be a major health concern for the elderly. Although smaller investigations indicate that auditory temporal processing also declines with age, such measures have not been included in larger studies. Temporal gap detection thresholds (TGDTs; an index of auditory temporal resolution) measured in 1071 listeners (aged 18–98 years) were shown to decline at a minimum rate of 1.05 ms (15%) per decade. Age was a significant predictor …


Word Recognition In Noise Among Young And Older Listeners: A Combined Behavioral And Electrophysiological Study, Victoria Ann Williams-Sanchez Nov 2014

Word Recognition In Noise Among Young And Older Listeners: A Combined Behavioral And Electrophysiological Study, Victoria Ann Williams-Sanchez

USF Tampa Graduate Theses and Dissertations

Word recognition is based on the complex interplay of bottom up processing of acoustic input and corresponding top-down processing based on linguistic redundancies (i.e., contextual cues). Friedrich and Kotz (2007) investigated the timeline of integrating top-down and bottom-up processes among young adults with normal hearing using sentences presented in quiet. As a follow-up study, also with young adults with normal hearing (Experiment 1 of this dissertation), we used sentences embedded in multi-talker background noise and found similar results to Friedrich and Kotz (2007); but, with the use of principal component analysis (PCA) unveiled additional effects of phonological and semantic integration …


Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb Jan 2012

Semantic Feature Distinctiveness And Frequency, Katherine Marie Lamb

USF Tampa Graduate Theses and Dissertations

Lexical access is the process in which basic components of meaning in language, the lexical entries (words) are activated. This activation is based on the organization and representational structure of the lexical entries. Semantic features of words, which are the prominent semantic characteristics of a word concept, provide important information because they mediate semantic access to words. An experiment was conducted to examine the importance of semantic feature distinctiveness and feature frequency in accessing the lexical representations of young and older adults in an off-line task using features of animals. The McRae, Cree, Seidenberg, and McNorgan (2005) feature norm corpus …
