Hemispheric Differences In Specificity Effects In Talker Identification, Julio Gonza´Lez, Teresa Cervera-Crespo, Conor T. Mclennan

Psychology Faculty Publications

In the visual domain, Marsolek and colleagues (1999, 2008) have found support for two dissociable and parallel neural subsystems underlying object and shape recognition: an abstract-category subsystem that operates more effectively in the left cerebral hemisphere (LH), and a specific-exemplar subsystem that operates more effectively in the right cerebral hemisphere (RH). Evidence of this asymmetry has been observed in priming specificity for linguistic (words, pseudoword forms) and nonlinguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects for linguistic (spoken words) and nonlinguistic (environmental sounds) stimuli. In the present study, the same asymmetrical pattern …

Monitoring Carboplatin Ototoxicity With Distortion-Product Otoacoustic Emissions In Children With Retinoblastoma, Shaum Bhagat, Johnnie Bass, Stephanie White, Ibrahim Qaddoumi, Matthew Wilson, Jianrong Wu, Carlos Rodriguez-Galindo

Faculty Publications

ObjectiveCarboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in …

Intelligibility Of Electrolarynx Speech Using A Novel Actuator, Brian Madden, Mark Nolan, Ted Burke, James Condron, Eugene Coyle

Conference Papers

During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. Following a laryngectomy, some people speak using an electrolarynx which replaces the excitatory function of the absent larynx. Drawbacks of conventional electrolarynx designs include the buzzing monotonic sound emitted, the need for a free hand to operate the device, and difficulty experienced by many laryngectomees in adapting to its use. Despite these shortcomings, it remains the preferred method of speech rehabilitation for a substantial minority of laryngectomees. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal …

Phonological Development In Hearing Children Of Deaf Parents, Erin N. Toohey

Honors Scholar Theses

Phonological development in hearing children of deaf parents Dr. Diane Lillo-Martin 5/9/2010 The researcher wishes to determine the significance of a unique linguistic environment on the effects of phonological development. The research examines whether 3 hearing children of deaf parents, hereafter referred to as CODAs, have inconsistencies, as compared to children in a typical linguistic environment, in their syllable structure, phonological processes or phonemic inventories. More specifically, the research asks whether their speech is more consistent with children of typical environments or more similar to children with phonological delays or disorders or articulation disorders. After the examination of these three …

Vocabulary Acquisition Of Bilingual Students Through The Implementation Of Dialogic Shared Storybook Reading Techniques, Samantha Kamille Ariaz

Children who are learning English as a second language and whose caregivers speak only Spanish were chosen to participate in the study. Parents were trained using Dialogic Shared Storybook Reading (DSSR) techniques (Whitehurst, 1988). The study was a single subject multiple baseline design across behaviors. Reading conditions were counterbalanced to control for acquisition of new vocabulary. There were a total of five participants, three children and two mothers (n=5). The participants were separated into two families. Each family was exposed to three reading book conditions while the parents implemented the specified techniques: 1. Shared reading with an electronic, bilingual Spanish/ …

A Survey Of Variables Influencing Speech-Language Pathologists' Use Of Evidence-Based Practice In Clinical Settings, Ailbhe Tressan Cormack

Open Access Theses & Dissertations

Although the need for evidence-based practice (EBP) in speech-language pathology has been well attested, multiple barriers hamper its implementation. Purpose: The purpose of this study was to compare variables influencing the use of EBP by practicing speech-language pathologists (SLPs). Method: Eighty-five SLPs based out of different primary work settings in El Paso, Texas responded to a survey addressing: 1. attitudes and perceived barriers toward EBP, 2. exposure to EBP, research methodology and statistics in graduate courses, 3. time in practice, 4. practice setting(s), 5. amount and nature of support for EBP in work settings, and 6. use of research literature …

Perception And Identification Of Voice Disorders: A Comparison Study Between Hispanic And Non-Hispanics, Jacqueline Nicole Lopez

Open Access Theses & Dissertations

The extent of public education in the Hispanic population regarding voice disorders has been unidentified thus far, motivating the current study to assess knowledge and perception of functional and organic voice disorders among Hispanic individuals in the El Paso region. The project involved an experimental research design to investigate whether demographic variables influenced the accuracy of knowledge of voice disorders in the general population residing in the Greater El Paso Region. Results indicate that the majority of the participants perceive articulation, fluency, and voice disorders as interchangeable and are unaware of the role of medical and rehabilitation professionals in the …

The Effect Of A Three Point Sensory Diet On Vocal And Verbal Behavior In A Non-Verbal Child On The Autism Scale, Chelsey Danielle Smith

Mahurin Honors College Capstone Experience/Thesis Projects

The study involved a single subject, a non-verbal child on the autism spectrum, in a clinical setting over a 10 week period. The subject was on a three point sensory diet that was administered before therapy sessions. The tactile, vestibular and proprioceptive systems were targeted with deep pressure touch, a suspension swing, and joint compression. The primary focus was on participation in therapy and language development with specific attention given to the increase of vocalizations and/or verbalizations. The child experienced the sensory diet for schedule of 1 week off, 2 weeks on, 1 week off, 2 weeks on, 1 week …

Skill Acquisition In Skin Cancer Detection, Craig Speelman, Katie Martin, Steven Flower, Terry Simpson

Research outputs pre 2011

Previous research has shown that the ability to detect potentially dangerous skin lesions is not improved by viewing a pamphlet describing the characteristic features of such lesions. A different approach to improving this skill was investigated in this study. 100 student recruits were tested to investigate the effect of practice at distinguishing between dangerous and nondangerous skin lesions. Around 30 minutes of such practice, viewing 360 pictures of skin lesions, provided a significant advantage in making decisions about a target set of dangerous and nondangerous lesions, compared to no practice or practice with a filler task. Viewing a skin cancer …

Communicative Competence In Persons With Aphasia: The Impact Of Executive Function, Judy Marie Mikola

Wayne State University Dissertations

The purpose of this study was to examine the relationship between executive function and performance on selected linguistic tasks in persons with aphasia secondary to left frontal lesions.

A group of 15 persons with aphasia (PWA) completed three communication board tasks of varying levels of complexity and structure. The subject's functional use of the picture/word communication board was tested during a Story Retelling task. In addition, the PWA's executive function skills were examined using six nonverbal tests. The PWA group performance scores were compared to that of the neurologically healthy control group.

Results demonstrated that the control group performed significantly …

Discrimination Of Tone Contrasts In Mandarin Disyllables By Naïve American English Listeners, Shari Salzhauer Berkowitz

Dissertations, Theses, and Capstone Projects

The present study examined the perception of Mandarin disyllabic tones by inexperienced American English speakers. Participants heard two naturally-produced Mandarin disyllables, and indicated if the two were the same or different. A small native Mandarin-speaking control group participated as well. All 21 possible Mandarin contrasts where the initial syllable varied but the final syllable stayed the same were tested. Acoustic analysis was performed on the stimuli under study. Mandarin subjects scored at ceiling on all contrasts. American English subjects performed poorly on contrasts where the difference in mean F0 was small, or where the difference in the offset F0 of …

Investigation Of Speech Samples From Typically Developing Preschool Age Children: A Comparison Of Single Words And Imitated Sentences Elicited With The Paba-E, Matthew William Olsen

Dissertations and Theses

Assessment of speech sound production in young children provides the basis for diagnosis and treatment of speech sound disorders. Standardized single-word articulation tests are typically used for identification of speech sound errors because they can provide an efficient means of obtaining a speech sample for analysis and comparison to same-age peers. A major criticism of single-word articulation tests is that they may not accurately reflect speech sound production abilities in conversation. Comparison of performance in single-word and conversational contexts has produced conflicting results in the available research.

The purpose of the present study was to compare speech samples obtained using …

Coherence In Stories Told By Adults With Aphasia, Heather Harris Wright, Anthony Koutsoftas, Gerasimos Fergadiotis, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

Discourse coherence is the conceptual organization of discourse and it can be subdivided into two types: global and local. Of interest for the current study is global coherence; that is, how the discourse relates to the overall topic (Glosser & Deser, 1990). Coherence has been measured in persons with aphasia (PWA) using different elicitation tasks (e.g., recounts, story retelling, event-casts) and different scoring methods (ie., rating scales, coherence, violations, total counts) and results have varied across studies (Christianson, 1995; Coelho & Flewellyn, 2003; Glosser & Deser, 1990; Ulatowska, et al., 2004). These differences may reflect differences in how coherence is …

Psychometric Properties Of The Pyramids And Palm Trees Test, Gerasimos Fergadiotis, Heather Wright, Gilson Capilouto

Speech and Hearing Sciences Faculty Publications and Presentations

The Pyramids and Palm Trees Test (PPT) is a nonverbal measure of semantic memory that has been frequently used in previous aphasia, agnosia, and dementia research. Very little psychometric information regarding the PPT is available. The purpose of this study was to investigate the psychometric properties of the PPT in a population of healthy college students. Results indicated that the PPT achieved poor test–retest reliability, failed to obtain adequate internal consistency, and demonstrated poor convergent validity, but showed acceptable discriminant validity. The results of this study suggest that the PPT lacks acceptable reliability and validity for use with a college …
