Challenges Facing A Complementary-Systems Approach To Abstract And Episodic Speech Perception, Conor T. Mclennan

Psychology Faculty Publications

It has been nearly a decade since the publication of Goldinger’s [4] Psych. Review paper in which he presented his episodic theory of lexical access. Moreover, Goldinger’s (and others’) empirical work [3, 14] providing evidence for episodic representations predates the formal presentation of his episodic theory. This is an appropriate time to note how the field has progressed in the past decade with respect to the debate over the nature of lexical representations. As evidenced by the two main papers, the emphasis is no longer on whether there are abstract and/or episodic representations. Instead, the focus is now on the …

Preverbal Language Abilities In Monozygotic And Dizygotic Twins, Sara Albrecht

Inquiry: The University of Arkansas Undergraduate Research Journal

This study examined prelinguistic language development of twins by delineating: differences from developmental expectations; twin-twin communication and twin-mother communication differences; and monozygotic-dizygotic differences. Nine families with twins between seven and 16 months of age participated in the study. Five families had dizygotic twins, three of which were male/female pairs, and four families had monozygotic twins, only one of which was female. The primary caregiver completed a developmental history. Data consisted of Dares Primitive Speech Acts (PSA) coding during in-home video-taping (30 minute sessions) with a second coding from the video material, and maternal reporting of vocabulary and communication using the …

Hemispheric Differences In Indexical Specificity Effects In Spoken Word Recognition, Julio Gonza´Lez, Conor T. Mclennan

Psychology Faculty Publications

Variability in talker identity, one type of indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. Furthermore, neuropsychological evidence suggests that indexical and linguistic information may be represented and processed differently in the 2 cerebral hemispheres, and is consistent with findings from the visual domain. For example, in visual word recognition, changes in font affect processing differently depending on which hemisphere initially processes the input. The present study examined whether hemispheric differences exist in spoken language as well. In 4 long-term repetition-priming experiments, the authors examined responses to stimuli that were primed by stimuli that …

Assessing Effectiveness Of The Differential Assessment Of Autism And Other Developmental Disorders (Daadd) As A Diagnostic Screening Instrument, Caroline Dahlstrom

Masters Theses

Children with developmental disorders were thought to be more similar than different in the past (Greenspan & Wieder, 1998). Many developmental disorders are a result of neurological differences and/or delays in a child's acquisition of general skills and can present similarly at a young age (Richard & Calvert, 2003). Therefore, there has recently been an emphasis on the need for developmental disorders to be differentiated because of the differences being noted. Many assessment tools, including specialized checklists, interview formats, and standardized tests used to assist in the diagnosis of developmental disorders are available. The Differential Assessment of Autism and other …

Methodological Variables For Eliciting Maximum Phonational Frequency Range In Adults, K. Lenee Moseley

Masters Theses

The current study employed an experimental research design to compare the effect of elicitation tasks (glissando versus discrete-steps) and the integration of visual feedback (auditory-only model versus visual feedback with an auditory model) on obtaining an individual's maximum phonational frequency range (MFPR). Participants included forty normal speaking males and females. A one-way ANOVA indicated the glissando elicitation task yielded a significantly higher MPFR than the discrete-steps elicitation task. [F (1,159) = 34.39; p < .01]. A one-way ANOVA approached but did not reach statistical significance [F (1,159) = 3.104, p = .08] for the difference between the auditory-only model and the auditory model with visual feedback. However, the frequency means depicted a larger MPFR when visual feedback was included within each of the elicitation tasks.

The Effects Of Augmentative And Alternative Communication On The Communication Attempts And Disruptive Behavior Of A Child With Autism, Natalie Arp

Masters Theses

This study evaluated the use of augmentative and alternative communication as a means to decrease disruptive behavior for a child in the autism spectrum. A case study with a training and treatment period was implemented. The dependent variables were the disruptive behaviors and the increased communication that occurred during a speech therapy treatment session. The independent variable was the implementation of augmentative and alternative communication, specifically, a modified Picture Exchange Communication System, (PECS) (Bondy & Frost, 1998) in combination with a VOCA (Twin Talk). The participant was a 3 1/2 year old female diagnosed with an Autistic Spectrum Disorder at …

The Effect Of Objective Data In Narrative Observation Notes On Changing Supervisee Behavior, Rudyard C. Watson

Masters Theses

The purpose of this research study was to determine if two different types of narrative observation notes impacted supervisee clinical behaviors. Narrative observation notes alone and narrative observation notes coupled with objective data were used as the independent variables. Sixteen supervisees and 5 supervisors participated in the study. The supervisees were divided into two numerically even groups of eight and provided with one of the independent variables.

The study consisted of eleven total therapy sessions, with the first three sessions providing baseline data and the following eight involved administration of the independent variables. Group one received narrative observation notes alone …

A Comparison Of School-Aged Children Who Stutter And Do Not Stutter In Difficult Phonological Tasks, Christopher Lading

Masters Theses

The purpose of this study was to assess the phonology skills of school-aged children who stutter using tasks that task the speech system. Participants included 11 children who stuttered and 10 normally fluent children. The results suggested that no differences exist in the phonology of children who stutter and children who are normally fluent when presented with complex phonological tasks.

Effect Of Adapted Phonic Faces Story Books On Phonological Skills Of Children With Severe Expressive Language Disorders, Meher Hormazd Banajee

LSU Doctoral Dissertations

Although No Child Left Behind (2001) encourages the inclusion of all children within the regular curriculum, children with severe speech and physical disabilities rarely are provided with the literacy education provided to grade-level peers. This study taught alphabetic skills to three children with severe speech and physical impairments in the context of traditional alphabet books versus Phonic Faces Storybooks. Both storybooks were converted into e-books using Microsoft Office PowerPoint (Microsoft Office, 2003) and accessed using a single rocking lever switch. Two graphemes were selected based on incorrect responses from the pretest administration of the The Phonological Awareness Test (Roberson & …

Expectation In Visual Symbolic Processing Of Environmental Symbols In People With Fluent Aphasia, Amanda Stead

LSU Master's Theses

The purpose of this study was to examine aspects of visual symbolic processing in those individuals with fluent aphasia, and how it compares to that of their lexical ability. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged controls. Participants were administered four computer based expectation tasks, two of which were symbolic, and two which were lexical. Each task contained a simple and a complex level. Participants were required to determine if the final stimulus, within a set of four, was congruent or incongruent. The measures taken included both reaction time and …

Motor Learning And Its Application To Accent Modification, Lindsey Nicole Clark

Dissertations and Theses @ UNI

As the numbers of immigrants and non-native speakers of English continue to be high in the United States, there will also continue to be those who wish to alter their manner of speaking. Currently, there is little research discussing the effectiveness of traditional therapy techniques (i.e. auditory training, drill, and phonetic placement; Schmidt and Meyers, 1995). However, in recent years, research has shown high success rates in therapies based on motor learning principles ( e.g. Backer, 2003; Mueller, 2004; Nelson, 2004). By definition, motor learning is "a set of processes associated with practice or experience leading to relatively permanent changes …

Comparison Of Ten Interventions For A 7-Year-Old With Unintelligible Speech, Sharynne Mcleod, Alison Holm, Sharon Crosbie, Barbara Dodd, Barbara W. Hodson, Michelle Morrisette, Judith A. Gierut, Deborah Hayden, Nicole Mueller, Joy Stackhouse, A. Lynn Williams, Caroline Bowen

ETSU Faculty Works

The management of speech impairment of unknown origin in children requires SLPs to make important clinical decisions around assessment, analysis, diagnosis and intervention. Ideally, clinicians should be guided in their decision making by evidence. Over thirty years ago, this was a relatively straightforward task. Most children’s speech problems were assessed, analysed and treated from an articulation perspective. Since the paradigm shift from articulation to phonology, clinical decision making has become more challenging. This challenge is in part due to the increase in possible approaches. This short course will outline the application of ten intervention approaches to one child and will …

Do Auditory Simulations Of Noise-Induced Hearing Loss Change Young Adults' Attitudes Towards Noise Exposure?, Claire Roockley

Theses : Honours

Noise-induced hearing loss (NIHL), or hearing damage from regular exposure to loud noise, can profoundly affect a person's hearing capabilities and overall well-being. Many individuals continue to expose themselves to hazardous levels of noise, and, in turn, put themselves at risk of developing a NIHL. This review critically examines the existing literature presented on NIHL. Emphasis is placed on the increasing prevalence of NIHL in young adults from exposure to loud recreational noise. The effectiveness of current educational strategies that have been employed to reduce or prevent the occurrence of NIHL in this cohort is also examined. Research indicates that …

Variability In Apraxia Of Speech: A Perceptual, Acoustic, And Kinematic Analysis Of Stop Consonants, Christopher Dromey, Shannon C. Mauszycki, Julie L. Wambaugh

Faculty Publications

Since being recognized as a clinical entity, the defining characteristics of apraxia of speech (AOS) have continued to evolve (McNeil, Robin, & Schmidt, 1997). Early research examining speech production with AOS speakers revealed inconsistency in articulatory performance with unpredictable errors (Johns & Darley, 1970; LaPointe & Johns, 1975). More recent research with “pure” apraxic speakers and AOS speakers with accompanying aphasia has revealed consistency in the location and types of errors in repeated productions (McNeil, Odell, Miller & Hunter, 1995; Shuster & Wambaugh, 2003; Wambaugh, Nessler, Bennett & Mauszycki, 2004). The issue of variability in AOS remains unresolved (Croot, 2002). …

Psychometrically Equivalent Russian Speech Audiometry Materials By Male And Female Talkers, Shawn L. Nissen, Richard W. Harris, Melissa G. Pola, David L. Mcpherson, George A. Tavarkiladze, Dennis L. Eggett

Faculty Publications

Despite the large number of individuals who speak Russian, only a limited number of high-quality speech audiometry materials are available in a standard dialect of Russian. Thus, the purpose of this study was to develop and evaluate speech audiometry materials that can be used to measure word recognition and SRT testing in quiet for native speakers of Russian. Familiar mono-syllabic and bisyllabic words were digitally recorded by male and female talkers of Russian and subsequently evaluated by native listeners. Using logistic regression, psychometric functions were then calculated for all words. Selected monosyllabic words were digitally adjusted to create word recognition …

Development Of Speech Reception Threshold Materials For Speakers Of Taiwan Mandarin, Shawn L. Nissen, Richard W. Harris, Katie B. Slade

Faculty Publications

The aim of this research was to develop, digitally record, evaluate, and equate speech audiometry materials that can be used to measure the speech reception threshold(SRT) in quiet for native speakers of Taiwan Mandarin. Familiar trisyllabic words were digitally recorded by male and female talkers of Taiwan Mandarin and subsequently evaluated by 20 native listeners with normal hearing at 14intensity levels (10 to 16 dB HL) in 2 dB increments. Using logistic regression, psychometric functions were calculated for all words. Twenty-eight words with comparatively steep psychometric functions were selected and digitally adjusted to match the mean subject pure-tone average (5.0 …

The Clinical Utility Of Mlu And Ipsyn For Aae-Speaking Children, Emily Lee Jones

LSU Master's Theses

The purpose of this study was to examine the clinical utility of two assessment measures for one group of nonstandard English dialect speakers, that of African-American English- (AAE) speaking children. The measures were mean length of utterance (MLU) and Index of Productive Syntax (IPSyn). The clinical utility of these measures was examined by comparing MLU and IPSyn values of three different groups of AAE speakers to determine if these measures are influenced by a child’s socio-economic status, dialect status, and/or clinical language status. An item analysis was also completed for IPSyn to determine if the items on this tool are …

Rate Change Effects On Acoustic Duration Measures On An Adolescent Who Stutters, Valerie Jean Courville

LSU Master's Theses

The purpose of this study was to determine if reduced rate techniques have an effect on speech motor coordination of an adolescent. A literature review revealed that a reduced rate technique consistently promoted more fluent speech; however, the cause of that increase in fluency is not known. This study proposed three specific questions to determine if there was a shortening of the /s/ phoneme in clustered contexts when compared to singletons, if reducing the rate would cause the adolescent to produce more adult-like shortening patterns, and if the reduced rate technique caused a decrease in stuttering events. One eleven year …

The Efficacy Of An Actor-Emotion Technique On Changing Communication Attitude In Children Who Stutter: A Treatment Outcome Study, Tiffany Marie Scavo

LSU Master's Theses

The purpose of the present study was to test the efficacy of an actor-emotion strategy approach on changing communication attitudes in an adolescent child who stutters. The participant for this study was an eleven-year, ten-month old male attending a public middle school in Baton Rouge, Louisiana who presented with a severe fluency disorder. The participant attended group sessions Monday-Thursday from 9:00-12:00 for 6 weeks as part of a fluency day camp. The study used a worksheet-based measure to evaluate emotionality on a daily basis. Using an ABA withdrawal design, two analyses were completed. The first analysis examined the stability or …

Expectation In Auditory Processing Of Environmental Sounds In People With Fluent Aphasia, Meghan Evelyn Collins

LSU Master's Theses

The purpose of this study was to examine the integrity of the nonverbal auditory system in subjects with fluent aphasia, and determine the relative preservation of the nonverbal auditory system in comparison to the lexical system. This was attempted through the task of expectation, a high level processing skill. Two groups of participants were examined: a group with fluent aphasia, and a group of non-neurologically damaged individuals. Participants were administered two nonverbal auditory conditions devoid of lexical information, a simple condition and a complex condition in which they were required to determine if the last sound heard in a sequence …

Prevalence Of Family History Of Speech-Language Impairment In An African American Sample, Tricia Mccully Rodrigue

LSU Master's Theses

The purpose of this study was to examine the prevalence of a positive family history of speech and/or language impairments in an African American sample. The first phase of the study used questionnaires from the primary caregivers of 161 children. The questionnaires allowed for an examination of family history as a function of a child’s socioeconomic level (+/- high school level of maternal education), educational placement (+/- receipt of services by a speech language clinician), and clinical status (+/- profile consistent with a diagnosis of SLI). The second phase of the study included interviews that were collected from 17 families …

Effects Of The Menstrual Cycle On The Vibratory Characteristics Of The Vocal Folds, Aimee Michelle Bonnette

LSU Master's Theses

The purpose of this study was to obtain preliminary data on several factors that may influence the vibratory patterns of the vocal folds in addition to the hormonal fluctuations present during the menstrual cycle. These factors included patient reports of severity of reflux symptoms, severity of premenstrual symptoms, and severity of negative vocal hygiene behaviors prior to each evaluation. Ten subjects who did not experience complaints of their voice participated in the study. Data from four subjects who were not on birth control and four on birth control were analyzed for the first cycle, which included self-perception, acoustic analysis, and …

A Study Of Auxiliary Be In African American English: A Comparison Of Children With And Without Specific Language Impairment, April W. Garrity

LSU Doctoral Dissertations

This study’s purpose was to examine the use of auxiliary BE forms in African American English (AAE)-speaking children with and without language impairment. The impetus for this work was a lack of information in the literature about BE use in AAE as a function of form, language status, and tasks, and the relevance of this type of data for testing one theoretical model of childhood language impairment, the Extended Optional Infinitive account (EOI; Rice, Wexler, & Cleave, 1995). Thirty African Americans participated: 10 six-year-olds with specific language impairment (SLI); 10 age controls (AM); and, 10 language controls (LM). All of …

Alphabetic And Phonemic Awareness In Toddlers, Pamela A. Terrell

LSU Doctoral Dissertations

The ability of 20-24 month-old toddlers to recognize graphemes and phonemes was investigated by reading a Phonic Faces (PF) alphabet picture book. Phonic Faces iconically picture a letter in the mouth of a character producing the sound (the curve of the P looks like the top lip popping the /p/ sound). The book was composed of nine letters and was read individually to experimental subjects three times weekly for six weeks. The control group received no treatment, but engaged in individual play activities for comparable time. Following six-weeks the groups alternated so the former control group now received the alphabet …

Language-Based Spelling Instruction For Children Who Are Hard-Of-Hearing, Brittney L. Yakey

Masters Theses

The purpose of the study was to evaluate the effectiveness of SPELL-Links to Reading and Writing, a language-based instructional spelling program, with two hard-of-hearing children. Spelling skills were evaluated using the Spelling Performance Evaluation for Language (SPELL), Wide Range Achievement Test (WRAT), and Featured Inventories. The participants included two hard-of-hearing children with mild hearing loss. Spelling intervention targeted four spelling patterns (short u, ck, ch/tch, and ng). The results showed that one child benefited from the SPELL-Links to Reading and Writing by the improvement across all four patterns, while the other child showed improvement in only two of the patterns.

Phonetic And Acoustic Analyses Of Two New Cases Of Foreign Accent Syndrome, Rosalie Perkins

Electronic Theses and Dissertations

This study presents detailed phonetic and acoustic analyses of the speech characteristics of two new cases of Foreign Accent Syndrome (FAS). Participants include a 48-year-old female who began speaking with an "Eastern European" accent following a traumatic brain injury, and a 45-year-old male who presented with a "British" accent following a subcortical cerebral vascular accident (CVA). Identical samples of the participants' pre- and post-morbid speech were obtained, thus affording a new level of control in the study of Foreign Accent Syndrome. The speech tasks consisted of oral readings of the Grandfather Passage and 18 real words comprised of the stop …
