Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes Jan 2013

Age-Related Changes To The Production Of Linguistic Prosody, Daniel Richard Barnes

Open Access Theses

The production of speech prosody (the rhythm, pausing, and intonation associated with natural speech) is critical to effective communication. The current study investigated the impact of age-related changes to physiology and cognition in relation to the production of two types of linguistic prosody: lexical stress and the disambiguation of syntactically ambiguous utterances. Analyses of the acoustic correlates of stress: speech intensity (or sound-pressure level; SPL), fundamental frequency (F0), key word/phrase duration, and pause duration revealed that both young and older adults effectively use these acoustic features to signal linguistic prosody, although the relative weighting of cues differed by group. Differences …

Stuttering behaviors were tracked …


Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten Jan 2013

Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten

Theses and Dissertations--Communication Sciences and Disorders

This study investigated the accuracy of healthy aging adults‟ self-rating of communication style, as measured by quantifiable measures of discourse performance. Ninety cognitively healthy adults participated and comprised three age cohorts (20s, 40s, 60s). Participants completed discourse tasks that included recounting a vacation, telling a story, and describing a picture. Participants also self-rated their communication style, placing them in a talkative or reserved cohort. Communication style was measured by discourse performance variables of interest: length of output (TNW) and informativeness (%IU). When presented with an unconstrained task (recounting a vacation), talkative and reserved groups, regardless of age, produced a similar …


The Effects Of Practice On The Concurrent Performance Of A Speech And Postural Task In Persons With Parkinson Disease And Healthy Controls, Christopher Dromey, K Bo Foreman, Stuart Sondrup, Eon Jarvis, Shawn Nissen, Leland E. Dibble Jan 2013

The Effects Of Practice On The Concurrent Performance Of A Speech And Postural Task In Persons With Parkinson Disease And Healthy Controls, Christopher Dromey, K Bo Foreman, Stuart Sondrup, Eon Jarvis, Shawn Nissen, Leland E. Dibble

Faculty Publications

Purpose. Persons with Parkinson disease (PD) demonstrate deficits in motor learning as well as bidirectional interference (the performance of one task concurrently interferes with the performance of another task) during dual-task performance. Few studies have examined the practice dosages necessary for behavioral change in rehabilitation relevant tasks. Therefore, to compare the effects of age and PD on motor learning during dual-task performance, this pilot study examined persons with PD as well as neurologically healthy participants during concurrent performance of postural and speaking tasks. Methods. Seven persons with PD and 7 healthy age-matched and 10 healthy young control subjects were tested …

Structural Processing Of Language Components: Detection And Comprehension, Samantha Rose Crow Jan 2013

Structural Processing Of Language Components: Detection And Comprehension, Samantha Rose Crow

Wayne State University Theses

Although music and language share many perceptually functional characteristics, research endeavors are still focusing on the underlying neural circuitry. Past research has indicated a distinction of hemispheric lateralization between music and language processing. Recently, efforts have shifted to the notion of an initial general shared pathway in the brain with auditory stimuli differentiated in later processing to specialized regions. Therefore, both linguistic and musical components have been examined in numerous experiments to discern the possible influence of music and language components on auditory perception and comprehension, including their potential interaction. However, the effects of sentential prosody on early language structural …


Social Story Intervention For Children Who Are Deaf Or Hard-Of-Hearing, Kaylee Mccollum Jan 2013

Social Story Intervention For Children Who Are Deaf Or Hard-Of-Hearing, Kaylee Mccollum

Undergraduate Honors Theses

Originally developed for children with mild autism, a Social Story is a short story that describes an ambiguous or troublesome situation and provides an appropriate response to that situation. Several research studies have confirmed the effectiveness of Social Stories in decreasing undesirable behaviors in children with mild, moderate, and severe autism spectrum disorder (ASD); however, limited research has been conducted to determine the efficacy of Social Stories in modifying behaviors of children who do not have autism. The purpose of this study was to determine the effectiveness of Social Stories in decreasing undesirable behaviors in children who are deaf or …

A Comparison Of Intervention Approaches Using The Ipad, Meredith Healy Jan 2013

A Comparison Of Intervention Approaches Using The Ipad, Meredith Healy

Undergraduate Honors Theses

Research has indicated that an interactive, naturalistic style of instruction facilitates vocabulary learning (Armbruster, Lehr, & Osborn, 2010; Beck, McKeown, & Kucan, 2005; Brett, Rothlein, & Hurley, 1996). Evidence also suggests that direct instruction is effective for children with language impairment (Jenkins, Pany, & Schreck, 1978; Boehm, 1986; Siefert & Schwarz, 1991). A reduced fast-mapping ability is characteristic of children with language impairment (Rice, Buhr, & Nemeth, 1990), necessitating additional support when providing vocabulary instruction (Steele & Mills, 2011) . As many forms of technology are being integrated into educational settings, it is imperative to consider the effects of technology …


Executive Functions As Rated By Teachers Of Preschool Children With Language Impairment And Typical Language Skills, Karissa Genenbacher Jan 2013

Executive Functions As Rated By Teachers Of Preschool Children With Language Impairment And Typical Language Skills, Karissa Genenbacher

Undergraduate Honors Theses

Executive functions (EFs) comprise an array of higher order cognitive skills which are important for the development of self-control and effective participation in home and school environments. Research has begun to identify executive function deficits in children with Specific Language Impairment (SLI) and in children who are at-risk for language impairment. The purpose of this study was to investigate differences in executive functioning skills of children with SLI, children demonstrating at-risk language, and children with typical language, based on teacher ratings of the Behavioral Rating inventory of Executive Function- Preschool (BRIEF-P). The relationships between executive functions and language skills …

Method: Previously created SRT and WR materials were presented to 32 Mandarin listeners with normal hearing:16 speakers of Mainland Mandarin and 16 speakers of Taiwan Mandarin. Hearing abilities were examined using SRT and WR materials created for speakers from 2 different regional dialects. Presentation of the materials occur red during 2 …


Narrative Discourse In Aphasia: Main Concept And Core Lexicon Analyses Of The Cinderella Story, Emily Patricia Dillow Jan 2013

Narrative Discourse In Aphasia: Main Concept And Core Lexicon Analyses Of The Cinderella Story, Emily Patricia Dillow

Theses and Dissertations

Discourse is a highly individualized and complex speech act essential for effective communication in daily life. Individuals with language disorders demonstrate impaired narrative ability and a resultant decline in functional communication (Webster, Franklin, & Howard, 2007). Discourse analysis is often time-consuming and impractical for everyday clinical use. Most informative discourse measures require specialized training to perform and are time-consuming. A clinically practical measurement is lacking. Standardized core lexicon and main concept lists for discourse tasks could allow clinicians to efficiently assess discourse skills and predict activity and participation limitations. This study presents the development and application of a core lexicon …

Reflective practice holds importance for health and education practitioners in Australia, as demonstrated by increased prominence in the revised Competency based Occupational Standards for speech pathologists. This paper explores the topic of reflective practice, in the clinical context, by addressing the following questions: What is reflective practice? Why is it an important skill for speech pathologists? What is the evidence base for reflective practice? How do practitioners and students engage in the process of reflection? In addressing the final question, four methods of facilitating reflection are outlined: journal reflection, reflection on a critical incident, reflection following professional development, and reflection …


Examining The Validity And Reliability Of The Infant-Toddler Meaningful Auditory Integration Scales (It-Mais) Via Rasch Analysis, Anne Denise Schubert Jan 2013

Examining The Validity And Reliability Of The Infant-Toddler Meaningful Auditory Integration Scales (It-Mais) Via Rasch Analysis, Anne Denise Schubert

LSU Master's Theses

In this study, we analyzed the validity and reliability of the Infant-Toddler Meaningful Auditory Integration Scales (IT-MAIS; Zimmerman-Phillips, Osberger, & Robbins, 2001), an assessment designed to measure listening skills in children ages 0-3 years. The IT-MAIS is a caregiver report tool used by speech-language pathologists and audiologists to assess listening skills in children with sensorineural hearing loss (SNHL) pre- and post-cochlear implant (CI). The IT-MAIS is widely used; however, it has not undergone thorough psychometric analysis. Using longitudinal data collected by the University of Iowa Children’s Cochlear Implant Program, we analyzed the psychometric properties of the IT-MAIS via Rasch analysis, …

Comparing Spoken Language Treatments For Minimally Verbal Preschoolers With Autism Spectrum Disorders, Rhea Paul, Daniel Campbell, Kimberly Gilbert, Ioanna Tsiouri Jan 2013

Comparing Spoken Language Treatments For Minimally Verbal Preschoolers With Autism Spectrum Disorders, Rhea Paul, Daniel Campbell, Kimberly Gilbert, Ioanna Tsiouri

Communication Disorders Faculty Publications

Preschoolers with severe autism and minimal speech were assigned either a discrete trial or a naturalistic language treatment, and parents of all participants also received parent responsiveness training. After 12 weeks, both groups showed comparable improvement in number of spoken words produced, on average. Approximately half the children in each group achieved benchmarks for the first stage of functional spoken language development, as defined by Tager-Flusberg et al. (J Speech Lang Hear Res, 52: 643–652, 2009). Analyses of moderators of treatment suggest that joint attention moderates response to both treatments, and children with better receptive language pre-treatment do better with …


Finding Similarities Between Photographs And The Stroke And Aphasia Quality Of Life Scale - 39 (Saqol-39) Items, Ashley Renee Brouwer Jan 2013

Finding Similarities Between Photographs And The Stroke And Aphasia Quality Of Life Scale - 39 (Saqol-39) Items, Ashley Renee Brouwer

LSU Master's Theses

Background: The Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39) is a valid, reliable quality of life (QoL) assessment for PWA (Hilari, 2003; Hilari, Byng, Lamping, & Smith, 2003). However, individuals with severe aphasia are unable to use it because their ability to comprehend the text is too severely impaired for accurate self-report (Hilari & Byng, 2009; Hilari et al., 2003; Hilari, Owen, & Farrelly, 2007). Proxy respondents often report on QoL measures for these individuals; however, studies suggest differences between proxy-reported and self-reported scores in less severe populations (e.g., Cruice, Worrall, Hickson, & Murison, 2005; Engell, Hütter, Willmes, & …


Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul Jan 2013

Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul

Communication Disorders Faculty Publications

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …


Roles Of Speech-Language Pathologists In The Neonatal Intensive Care Unit, Katy Lane Greenlee Jan 2013

Roles Of Speech-Language Pathologists In The Neonatal Intensive Care Unit, Katy Lane Greenlee

Honors Theses

This thesis examined the roles of speech-language pathologists (SLPs) within the Neonatal Intensive Care Unit (NICU). In 2004, the American Speech-Language-Hearing Association published a set of policy documents regarding speech-language pathology practice in the NICU. Research compiled in the literature review explained and supported each of the roles listed in the ASHA policy documents. The literature also revealed that very few sources specific to the speech-language pathology field addressed roles other than those related to feeding and swallowing evaluation and intervention. This research investigated ASHA-certified, masters-level SLPs' familiarity with each of their possible roles in the NICU, as well as …


Experiences Of Speech-Language Pathology Graduate Students: An Exploratory Phenomenological Study, Anysia J. Ensslen Jan 2013

Experiences Of Speech-Language Pathology Graduate Students: An Exploratory Phenomenological Study, Anysia J. Ensslen

Theses and Dissertations--Educational Leadership Studies

Within the past decade little research has been conducted in the United States to examine the preparedness of beginning speech-language pathologists; the seminal article used for this research study comes from the United Kingdom (Horton, Byng, Bunning, & Pring, 2004). Literature from the past few decades indicates that there may be deficiencies in the way that beginning speech-language pathologists are being trained clinically.

The review of the literature suggests that the field may lack a clear and broadly supported learning theory or framework for the clinical supervision and training of speech-language pathology graduate students. The literature further supports the importance …


Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas Jan 2013

Supporting Speech-Language Pathologist Evidence-Based Practice Use: A Mixed-Methods Study In Skilled Nursing Facilities Within The Promoting Action On Research Implementation In Health Services Framework, Natalie Franko Douglas

USF Tampa Graduate Theses and Dissertations

As the management of dementia is a significant public health concern, efforts to increase access to effective treatments to a greater number of residents with dementia in skilled nursing facilities (SNFs) are warranted. The treatment addressed in this study, non-electronic external memory aids, is an evidence-based practice that has been found to increase positive communicative interactions and decrease negative behavioral problems of residents with dementia in SNFs.

Although use of memory aids is recommended, there are significant barriers such as lack of time and resources that inhibit the use of effective treatments in typical clinical settings. To address such barriers …


Does The Use Of Personally Relevant Stimuli In Semantic Complexity Training Facilitate Improved Functional Communication Performance Compared To Non-Personally Relevant Stimulus Items Among Adults With Chronic Aphasia?, Stephanie Karidas Jan 2013

Does The Use Of Personally Relevant Stimuli In Semantic Complexity Training Facilitate Improved Functional Communication Performance Compared To Non-Personally Relevant Stimulus Items Among Adults With Chronic Aphasia?, Stephanie Karidas

USF Tampa Graduate Theses and Dissertations

This study investigated the influence of semantic complexity treatment in individuals with fluent aphasia on discourse performance. Semantic treatment is an effective way to improve semantically based word retrieval problems in aphasia. Treatment focused on the semantic application of the Complexity Account of Treatment Efficacy (CATE) (Thompson, Shapiro, Kiran, & Sobecks, 2003) promotes training of complex items resulting in generalization to less complex, untrained items. In addition, research has shown that the personal relevance of treatment material can increase treatment efficacy. This study investigated the effect of semantic treatment of atypical personally relevant items among individuals with aphasia on discourse …


The Effect Of Rate Change On The Relative Timing Of Speakers With Multiple Sclerosis, Brandlynn N. Reister Jan 2013

The Effect Of Rate Change On The Relative Timing Of Speakers With Multiple Sclerosis, Brandlynn N. Reister

USF Tampa Graduate Theses and Dissertations

Relative timing ratios are a useful measure for determining the temporal regularities of speech. The timing intervals that make up these ratios are thought to be important when creating the motor plan for an utterance (Weismer & Fennell, 1985). In fact, these ratios have been shown to be remarkably stable, even when speakers deliberately increase their rate (Tuller & Kelso, 1984; Weismer & Fennell, 1985). The constancy of these ratios also has been demonstrated in speakers with known speech timing disturbances, like the dysarthrias associated with Parkinson's and Huntington's disease (Goberman & McMillan; Ludlow, Connor, & Bassich, 1987; Weismer & …


Nonword Processing In Bilingual Five Year Olds: Do Phonotactics Count?, Kyna Betancourt Jan 2013

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 …


Effects Of Speech Production Ability On A Measure Of Speech Perception Capacity In Young Children With Cochlear Implants And Their Articulation-Matched Peers, Victoria Beatriz Gonzalez Jan 2013

Effects Of Speech Production Ability On A Measure Of Speech Perception Capacity In Young Children With Cochlear Implants And Their Articulation-Matched Peers, Victoria Beatriz Gonzalez

USF Tampa Graduate Theses and Dissertations

With reductions in the age criterion for cochlear implantation, the need for age-appropriate measures of speech perception skills has increased. One recently developed tool that shows great promise for the clinical assessment of auditory speech perception capacity in young children with cochlear implants is the On-Line Imitative Test of Speech-Pattern Contrast Perception (OlimSpac). The OlimSpac requires a child to imitate nonword utterances by providing a verbal response. The child's perceptual abilities are inferred from the child's productions through having a listener, who is masked to the stimulus select the utterance produced by the child in an eight-alternative force-choice task. Although …


Comparing The Treatment Effect Of Conversational And Traditional Aphasia Treatments On Linguistic Complexity Measures, Kelsey Ann Copperberg Jan 2013

Comparing The Treatment Effect Of Conversational And Traditional Aphasia Treatments On Linguistic Complexity Measures, Kelsey Ann Copperberg

LSU Master's Theses

Linguistic complexity is frequently analyzed in studies of child language acquisition and impairment (Heilmann, Miller, & Nockerts, 2010; Price, Hendricks, & Cook, 2010) and the language of aging adults (Capilouto, Wright, & Wagovich, 2005; Kemper & Sumner, 2001; Kemper, Thompson, & Marquis, 2001; Kynette & Kemper, 1986; Shewan & Henderson, 1988) to document changes over time. There is little, if any, literature applying linguistic measures to analyze the language of individuals with aphasia as well as to analyze effects of different treatment measures. The current study analyzed semantic and syntactic components of linguistic complexity used by people with aphasia (PWA) …


Brain Electrophysiological Correlates Of Masked Picture Priming In Fluent And Stuttering Adults, Kalie B. Morris Jan 2013

Brain Electrophysiological Correlates Of Masked Picture Priming In Fluent And Stuttering Adults, Kalie B. Morris

USF Tampa Graduate Theses and Dissertations

Abstract

Objective: The aim of the present study was to investigate mechanisms of real-time language production of adults who stutter.

Method: Data were analyzed for 19 typically fluent young adults (TFA) and 19 young adults who stutter (AWS). Participants performed a masked picture priming task where priming stimuli consisted of two conditions 1) Identity- a masked printed prime word identical to the picture target label, and 2) Unrelated- a masked printed prime word unrelated to the picture target label. Brain event-related potentials (ERPs), time-locked to pictures eliciting spontaneous naming, were recorded, as well as naming accuracy and reaction times.

Results: …


Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson Jan 2013

Speech Sensorimotor Learning Through A Virtual Vocal Tract, Jeffrey J. Berry, Cassandra North, Benjamin Meyers, Michael T. Johnson

Speech Pathology and Audiology Faculty Research and Publications

Studies of speech sensorimotor learning often manipulate auditory feedback by modifying isolated acoustic parameters such as formant frequency or fundamental frequency using near real-time resynthesis of a participant's speech. An alternative approach is to engage a participant in a total remapping of the sensorimotor working space using a virtual vocal tract. To support this approach for studying speech sensorimotor learning we have developed a system to control an articulatory synthesizer using electromagnetic articulography data. Articulator movement data from the NDI Wave System are streamed to a Maeda articulatory synthesizer. The resulting synthesized speech provides auditory feedback to the participant. This …
