Towards Precision Audiology: Perceptual Profiles & Their Relation To Ecologically Valid Communication Assessments, Dana Cherri

USF Tampa Graduate Theses and Dissertations

Living in a sonic world, a person with hearing loss experiences difficulty in communicating with others. One of the reasons why some people with hearing loss do not wear hearing aids (HAs) is limited perceived benefit, which may result from HAs that are not fit using “best practices” or because the best practices fail to address individual difficulties experienced by the listener. The typical audiogram provides information regarding audibility as a function of frequency and is used to establish degree, type, and configuration of hearing loss, but does not measure the ability of an individual to process various components of …

Directing Attention In Second Language Phonological Contrast Learning, Laura Conover

USF Tampa Graduate Theses and Dissertations

Why are some people better at learning new languages than others? There is a rich body of research examining this issue from multiple perspectives and at all levels of language. This study attempts to add to that knowledge at the most fundamental level of language by examining potential influences on the learning of novel phoneme contrasts. The purpose of this study was to explore whether individual differences in attentional capabilities would help adults learn a non-native phonological contrast, and whether providing explicit directions that would guide the learners’ attention could help boost their performance. VCV recordings of the Thai /p/ …

Aligning Voice And Communication With Identity – A Survey On Transgender And Gender Diverse Populations, Rachel T. Chalom

USF Tampa Graduate Theses and Dissertations

Purpose: This research has two goals. The first goal is to examine transgender (TG) and gender diverse (GD) voice and communication functioning and the impact of voice on their everyday lives. The second goal is to examine the knowledge, attitudes, and beliefs speech-language pathologists (SLP) have about the TG and GD community and to investigate the relationship between self- and listener-perception and its correspondence to quality of life (QoL).

Methods: A total of 59 participants took part in this research. The research was separated into two parts, the first included 24 TG and GD individuals who participated in a Qualtrics …

Supporting Persons With Dementia In Communicating Their Care Preferences, Vanessa L. Burshnic

USF Tampa Graduate Theses and Dissertations

Person-centered care is important to the quality of life of nursing home residents with dementia. Preference assessments enable person-centered care by documenting residents’ preferred activities. Residents with severe dementia are less likely to have a role in preference assessment due to communication challenges associated with the disease. External supports (visual and text cues) are effective in improving the communication of residents with dementia, but these cues are often not used in practice. Standard assessment (verbal questioning) places greater demands on short-term memory and attention, which are known deficits in dementia.

Applying a within-subjects design, this study evaluated two conditions (standard …

Neuro-Correlates Of Word Processing Among Four-And-Five-Year-Old Children From Homes Varying In Socio-Economic Status, Wendy Olsen

USF Tampa Graduate Theses and Dissertations

A large body of research relates families’ socioeconomic status (SES) to child language development (Hoff & Tian, 2005). Results from these studies indicate preschoolers from low SES backgrounds may have underdeveloped linguistic foundations required for future academic success (Sirin, 2005; Lacouri & Tissington, 2011). These differences have been said to create a 30 million word-gap between the language experiences of low and middle to high SES children by the age of 3 years. Thus, children who come from lower SES backgrounds often lack the vocabulary knowledge used in school and in textbooks (Hart & Risley, 1995). One index of SES …

Early Literacy Abilities In Spanish-English Emergent Bilingual Children From Varied Dialectal Backgrounds, Antonietta Mastrota

USF Tampa Graduate Theses and Dissertations

The Hispanic population within the United States has grown to a considerable amount. The state of Florida’s population is 25% Hispanic, with projected estimates of this population continuing to grow in the coming years (Ortman & Shin, 2011). Statistics show that 28.3% of the state’s population, over the age of five, speak a language other than English at home. With this considerable number of Spanish-speakers comes the responsibility to adjust certain educational practices to best meet their needs. Literacy is an essential part of learning, and therefore assessing early literacy is an essential part to any child’s academic development.

Articulatory Patterns In Children Who Use Cochlear Implants: An Ultrasound Measure Of Velar Stop Production In Bilingual Speakers, Katherine Javier

USF Tampa Graduate Theses and Dissertations

Coarticulation occurs in running speech when one speech sound or phoneme overlaps with another. It can be considered a result of the way we sequence and organize our articulators to efficiently produce consecutive consonants and vowels in fluent speech. Previous research has suggested that measures of coarticulation can provide insight into the maturity of the motor speech planning system (Barbier, Perrier, Ménard, Payan, Tiede, & Perkell, 2013; Zharkova & Hewlett, 2009; Zharkova, Hewlett, & Hardcastle, 2011). Speech stability has also been suggested as an indicator of motor speech maturity in previous research using ultrasound imaging of velar-vowel targets (Frisch, Maxfield, …

The Impact Of Vocabulary Knowledge On Nonword Judgments In Spanish-English Bilinguals, Marisa E. Leyden

USF Tampa Graduate Theses and Dissertations

This thesis suggests that the range of vocabulary in an individual’s lexicon has an influence on in their assessment of nonword wordlikeness. The study included thirteen Spanish-English bilinguals who participated in a language dominance questionnaire, standardized assessments of Spanish and English vocabulary knowledge, and Spanish and English wordlikeness judgment tasks. Resulting data demonstrated moderate correlations between vocabulary knowledge and performance on nonword wordlikeness judgement tasks in Spanish and English. Participants with larger lexicons appeared more tolerant of less probable nonwords, those with low phonotactic probability, while those with smaller lexicons were less accepting of nonwords with low phonotactic probability. The …

Neural And Behavioral Mechanisms Of Clear Speech, Jenna Silver Luque

USF Tampa Graduate Theses and Dissertations

Clear speech is a speaking style that has been shown to improve intelligibility in adverse listening conditions, for various listener and talker populations. Clear-speech phonetic enhancements include a slowed speech rate, expanded vowel space, and expanded pitch range. Although clear-speech phonetic enhancements have been demonstrated across a variety of talkers, only a subset of these changes may be required for listeners to benefit perceptually from clear speech. Furthermore, while current literature has provided some understanding of the phonetic enhancements that are typical of clear speech and the improvements in intelligibility resulting from its use, less is understood regarding how listeners …

Static And Dynamic Spectral Acuity In Cochlear Implant Listeners For Simple And Speech-Like Stimuli, Benjamin Anderson Russell

USF Tampa Graduate Theses and Dissertations

For cochlear implant (CI) listeners, poorer than normal speech recognition abilities are typically attributed to degraded spectral acuity. However, estimates of spectral acuity have most often been obtained using simple (tonal) stimuli, presented directly to the implanted electrodes, rather than through the speech processor as occurs in everyday listening. Further, little is known about spectral acuity for dynamic stimuli, as compared to static stimuli, even though the perception of dynamic spectral cues is important for speech perception.

The primary goal of the current study was to examine spectral acuity in CI listeners, and a comparison group of normal hearing (NH) …

Hesitation Rate As A Speaker-Specific Cue In Bilingual Individuals, Jamie Lynn Armbrecht

USF Tampa Graduate Theses and Dissertations

Hesitation use is common among all speakers, regardless of whether they are engaged in their dominant or non-dominant language (Fehringer & Fry, 2007; Reed, 2000). The question is whether a bilingual speaker will engage in the same types of hesitations in both languages. If hesitation patterns can be identified consistently across speakers regardless of language, their use as an acoustic cue for speaker identification may be possible. This study examines differences in hesitation use across languages and speaking contexts (reading vs. conversation) in bilingual speakers.

Twenty Spanish-English bilinguals (ages 19 -31 years) were tested as part of a larger speaker …

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 …

Nonword Processing In Bilingual Five Year Olds: Do Phonotactics Count?, Kyna Betancourt

USF Tampa Graduate Theses and Dissertations

Phonotactic processing is foundational to the word processing task in both monolingual and bilingual children (Li & Farkas, 2002; Pierrehumbert, 2001; Shook & Marian, 2013; Storkel & Morrisette, 2002). While the use of phonotactic information in word processing in monolingual children is relatively well documented, it is less well understood in bilingual children. The purpose of this study was to investigate how bilingual kindergartners process the phonotactic probabilities of their two languages. A set of nonwords was developed that manipulated the strength of phonotactic probability across both Spanish and English while also controlling the language environment of the experimental task …

Exploring Picture Word Priming Effects In Healthy Aging Adults Using Event Related Potentials, Sasha C. Christopher

USF Tampa Graduate Theses and Dissertations

Objective: The aim of the present study was to investigate the mechanics with which older adults activate and access different subdomains of their mental lexicons during word retrieval for picture naming.

Method: Data were analyzed for 12 aging, native English speakers who performed a picture-word priming task. The auditory probe words were presented in the following conditions in relation to the picture stimuli: Identically related, strongly semantically related, weakly semantically related, strongly phonologically related, weakly phonologically related, semantically related to the strong phonological relative of the target picture label, or phonologically-related to the strong semantic relative of the target picture …

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 …

Perspective Shifting In Relative Clauses By Elementary-Aged Spanish-English Bilinguals: A Cross-Linguistic Study, Xigrid Tayri Soto

USF Tampa Graduate Theses and Dissertations

Language-specific theories of sentence processing suggest that individuals interpret sentences based on the characteristics of their native language (e.g., Bates & MacWhinney, 1989). As such, competing linguistic cues are taken into account (including word order, morphology, and animacy) and the cue selected is most likely to yield a correct interpretation in the native language. However, research in this area has produced conflicting results. MacWhinney (2005) has proposed that examining the role of perspective shifting in sentence comprehension may demonstrate how cognitive and syntactic factors work together to facilitate sentence comprehension. The aim of the current study is to investigate the …
