The Social Validity Of Telepractice Among Spanish-Speaking Caregivers Of English Learners: An Examination Of Moderators, Lisa Fitton, Kristina N. Bustamante, Carla Wood

Faculty Publications

The purpose of the present paper was to examine the social validity of telepractice as a service delivery model for Spanish-speaking families of English learners. Quantitative survey methodology was employed to examine 79 caregivers' opinions regarding telepractice and to obtain background information about participants' home environments. Findings revealed that approximately 46% of the participant sample reported being interested in their children receiving services via telepractice. Caregivers reported limited familiarity with telepractice as an option, but were likely to express interest if their child had an identified speech or language disorder or if they were interested in increased access to Spanish …

The participant completed three seven-week writing interventions focused on narratives, opinion essays, and persuasive essays. Intervention was …

Print Referencing Intervention During Shared Storybook Reading For Preschool Children With Hearing Loss, Sara Lawrence

Theses and Dissertations

The purpose of the current study was to evaluate the effectiveness of a print referencing book-reading intervention among children with hearing loss. Two preschool children with hearing loss who are developing listening and spoken language participated in this single subject study. The children participated individually in print referencing book-reading intervention (10 minute session once a week for 7 weeks). Assessment of children’s print knowledge skills occurred at the beginning of each session. Print referencing book-reading intervention was associated with gains in conceptual print knowledge. Further study is needed in this area.

Intensifying English Vocabulary Instruction For English Language Learners, Lisa A. Fitton Ph.D., Kristina Nichole Bustamante, Mary Claire Wofford, Dana Brown, Clariebelle Gabas, Rachel Hoge, Carla Wood

Faculty Publications

English vocabulary development is a key component of language and literacy development for English language learners (ELLs) living in the United States. With the increase in the number of speech-language pathologists (SLPs) with ELLs on their caseloads, it has become increasingly important for SLPs to be able to facilitate vocabulary growth in ELLs. To assist SLPs working with ELLs in schools, the present paper provides an overview of strategies to enhance English vocabulary instruction for ELLs, drawing on evidence from research with both monolingual and bilingual students. Strategies included are: leveraging the native language, teaching comprehension monitoring, embedding instruction in …

Comparing Methods For Assessing The English Grammatical Development Of Spanish-Speaking English Learners, Lisa A. Fitton Ph.D., Mary Claire Wofford, Kristina N. Bustamante, Natasha De Novi, Bibiana Nuñez, Carla L. Wood

Faculty Publications

Identifying valid and informative approaches for assessing young English learners (ELs) is essential for school-based speech-language pathologists (SLPs). The present paper focuses on two distinct approaches for assessing English grammatical development, a key component and indicator of language development for ELs. The approaches addressed are standardized normreferenced assessment and grammatical feature coding from story retell narratives. The authors review the utility of these approaches for evaluating the English grammatical development of Spanish-speaking ELs. A research example is provided to illustrate how a small sample (n = 18) of ELs performed on each of these English-based tasks. Findings reveal that children …

Towards Improving The Evaluation Of Speech Production Deficits In Chronic Stroke, Artemis Alexandra Basilakos

Theses and Dissertations

One of the most devastating consequences of stroke is aphasia - a disorder that impairs communication across the domains of expressive and receptive language. In addition to language difficulties, stroke survivors may struggle with disruptions in speech motor planning and/or execution processes (i.e., a motor speech disorder, MSD). The clinical management of MSDs has been challenged by debates regarding their theoretical nature and clinical manifestations. This is especially true for differentiating speech production errors that can be attributed to aphasia (i.e., phonemic paraphasias) from lower-level motor planning/programming impairments (i.e., articulation errors that occur in apraxia of speech; AOS). Therefore, the …

Neural And Behavioral Correlates Of Planning During Vocal Motor Control, Stacey Jean Sangtian

Theses and Dissertations

Speech is a goal-directed movement developed to serve the purpose of human communication. During speech, the brain simultaneously coordinates complex motor behavior and sensory information for planning, execution and online monitoring for error correction in order to ensure accurate delivery of the vocal messages. Models of speech production and voice motor control have adapted the principles of the internal forward model to explain that speech sound production is controlled by comparison of internal predictions with sensory feedback. Growing evidence from studies conducted in speech and limb motor movement indicate that these sensory predictions and responsive commands are loaded in anticipation …

Determining The Validity Of A Web-Based, Self-Rating Checklist Assessment Of Vocabulary Knowledge, Sheida Abdi

Theses and Dissertations

The purpose of this study is to examine the validity of a web-based, self-rating checklist of vocabulary knowledge. One hundred fifty-nine participants took two norm-referenced assessments in addition to one of three conditions of a developed self-rating checklist. Each condition employed a different combination of follow-up questions (synonym generation to verify participants’ self-ratings) and feedback for student responses (whether or not synonyms are correct). Condition 1 did not provide any follow-up questions or feedback, Condition 2 included follow-up questions and feedback, and Condition 3 presented follow-up questions but no feedback. Results show that participants moderately overestimated vocabulary knowledge. Moderate-to-high statistically …

Psycholinguistics In Fluency Disorders: Prearticulatory Speech Planning In Stuttering And Cluttering, Emily O’Dell Garnett

Theses and Dissertations

The Covert Repair Hypothesis (CRH) is an account for speech errors in normally fluent speakers, and also hypothesizes errors in the phonological encoding stage in people who stutter (PWS). Previous research has shown that PWS exhibit poorer performance compared to typically fluent adults (TFA) on linguistic tasks designed to tap into the level of phonological encoding, such as phoneme monitoring. Stuttering and cluttering often co-occur, thus the field can benefit from extending this methodology to study people who clutter (PWC). Experiment 1 in Chapter 2 used phoneme monitoring to study phonological encoding in PWS and PWC, with three conclusions: (1) …

Neural Correlates Of Verb Argument Structure Processing, Svetlana Malyutina

Theses and Dissertations

Verb argument structure (VAS) is pivotal to sentence production and comprehension, since it determines participant roles, as well as their grammatical form and syntactic position in a sentence. Neural correlates of VAS processing have mainly been studied in terms of the number of arguments. Data on the neural and behavioral effects of other VAS characteristics are limited, whereas they would have implications for behavioral and brain stimulation treatments of language disorders.

The present research investigated behavioral and neural effects of three understudied VAS characteristics (number of subcategorization options, number of thematic options and number of number-of-argument options) in single-word-level and …

Eye Movements Of Individuals With Aphasia During Reading And Scene Viewing, Kimberly G. Smith

Theses and Dissertations

Purpose: This project characterized eye movements of individuals with aphasia and age-matched participants during reading and scene viewing.

Methods: Individuals with aphasia (N=24) and age-matched controls participants (N=24) completed three eye tracking studies. Study 1 examined task-related changes in eye movements for scene search, scene memorization, text-reading, and pseudoreading. Ex-Gaussian, analysis of variance, and correlational analyses were used to compare differences in eye movements across tasks and participant groups. Study 2 examined how oculomotor and linguistic processing influence eye movements for textreading and pseudo-reading. In addition to the statistical analyses used in Study 1, four case studies were carried out …

Effects Of Language Predictability And Speech Rate On Speech Entrainment Performance In Healthy Individuals, Honey Isabel Hubbard

Theses and Dissertations

Speech entrainment, a paradigm in which a participant shadows the speech of an audiovisual model in real time, has been show to benefit individuals with non-fluent aphasia. A study examining the effects of language predictability and speech rate was conducted to understand factors that influence speech entrainment performance.

A recent study by Fridriksson and colleagues (2012) demonstrated that training with speech entrainment significantly increased the number of words participants with non-fluent aphasia were able to produce. Perhaps even more remarkably, these effects showed generalization. As a result, speech entrainment could be used to rehabilitate speech impairment in stroke. However, there …

Structured Narrative Retell Instruction For Young Children From Low Socioeconomic Backgrounds: A Preliminary Study Of Feasibility, Suzanne M. Adlof, Angela N. Mcleod, Brianne Leftwich

Faculty Publications

Successful acquisition of literacy depends on adequate development of decoding skills as well as broader, meaning-related knowledge and skills for text comprehension. Children from low socioeconomic status (SES) backgrounds are often challenged in both domains, relative to peers who are not economically disadvantaged. The efficacy of code-focused instructional programs for at-risk preliterate children is well supported, but less evidence is available regarding interventions to improve broader language and comprehension skills. This preliminary study tested the feasibility of a new intervention, "structured narrative retell instruction" (SNRI), and explored its potential to enhance meaning-related knowledge and skills, including vocabulary, listening comprehension, and …

Efficacy Of Video Modeling For Treatment Of Selective Mutism In Children, Danielle Newberry Phillips

Theses and Dissertations

Selective mutism is an extremely rare socio-pragmatic communication disorder that affects less than 1% of the population. The treatment of selective mutism may be addressed via many different approaches, including drug therapies and behavioral approaches or combinations of both. Self-modeling is a behavioral approach and is similar to that of video modeling. Video modeling treatment is becoming a more popular approach to serve individuals with social and behavioral disorders. Video modeling has been documented to improve social and behavioral deficits in individuals with Autism Spectrum Disorders. Because selective mutism is a rare condition and because the effects of video modeling …

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 …

Acquisition Of Initial Mental Graphemic Representations By Children At Risk For Literacy Development, Kenn Apel, Shurita Thomas-Tate, Elizabeth B. Wilson-Fowler, Danielle Brimo

Faculty Publications

We examined the acquisition of initial mental graphemic representations (MGRs) by 46 kindergarten children (mean age = 5 years, 9 months) at risk for literacy development because of low socioeconomic status. Using a storybook context, we exposed children to novel nonwords that varied in their phonotactic and orthotactic probabilities and then assessed the children's development of initial MGRs through spelling and reading recognition tasks. The children developed some initial MGRs but less than past reports of children from middle socioeconomic backgrounds. Children with more advanced word recognition abilities developed more initial MGRs than their peers with less advanced word recognition …

Network Modulation During Complex Syntactic Processing, Dirk B. Den Ouden, Dorothee Saur, Wolfgang Mader, Björn Schelter, Sladjana Lukic, Eisha Wali, Jens Timmer, Cynthia K. Thompson

Faculty Publications

Complex sentence processing is supported by a left-lateralized network including inferior frontal cortex and posterior superior temporal cortex. This study investigates the pattern of connectivity and information flow within this network. We used fMRI BOLD data derived from 12 healthy participants reported in and earlier study (Thompson, C. K., Den Ouden, D. B., Bonakdarpour, B., Garibaldi, K. & Parrish, T. B. (2010b). Neural plasticity and treatment-induced recovery of sentence processing in agrammatism. Neuropsychologia, 48(11), 3211-3227) to identify activation peaks associated with object-cleft over syntactically less complex subject-cleft processing. Directed Partial Correlation Analysis was conducted on time series extracted from …

Cerebral Perfusion In Chronic Stroke: Implications For Lesion-Symptom Mapping And Functional Mri, Jessica D. Richardson, Julie M. Baker, Paul S. Morgan, Chris Rorden, L. Bonilha, Julius Fridriksson

Faculty Publications

Lesion-symptom mapping studies are based upon the assumption that behavioral impairments are directly related to structural brain damage. Given what is known about the relationship between perfusion deficits and impairment in acute stroke, attributing specific behavioral impairments to localized brain damage leaves room for speculation, as impairments could also reflect abnormal neurovascular function in brain regions that appear structurally intact on traditional CT and MRI scans. Compared to acute stroke, the understanding of cerebral perfusion in chronic stroke is far less clear. Utilizing arterial spin labeling (ASL) MRI, we examined perfusion in 17 patients with chronic left hemisphere stroke. The …

Neural Plasticity And Treatment-Induced Recovery Of Sentence Processing In Agrammatism, Cynthia K. Thompson, Dirk B. Den Ouden, Borna Bonakdarpour, Kyla Garibaldi, Todd B. Parrish

Faculty Publications

This study examined patterns of neural activation associated with treatment-induced improvement of complex sentence production (and comprehension) in six individuals with stroke-induced agrammatic aphasia, taking into account possible alterations in blood flow often associated with stroke, including delayed time-to-peak of the hemodynamic response function (HRF) and hypoperfused tissue. Aphasic participants performed an auditory verification fMRI task, processing object cleft, subject cleft, and simple active sentences, prior to and following a course of Treatment of Underlying Forms (TUR; Thompson et al., 2003), a linguistically based approach for treating aphasic sentence deficits, which targeted objective relative clause constructions. The patients also were …

The Effect Of Semantic Set Size On Word Learning By Preschool Children, Holly L. Storkel, Suzanne M. Adlof

Faculty Publications

Purpose - The purpose was to determine whether semantic set size, a measure of the number of semantic neighbors, influenced word learning, and whether the influence of semantic set size was broad, showing effects on multiple measures both during and after learning.

Method - Thirty-six preschool children were exposed to 10 nonobjects, varying in semantic set size, paired with 10 nonwords, controlling phonotactic probability and neighborhood density. Nonobject-nonword pairs were presented in a game format. Learning was measured in naming and referent identification tasks administered before, during, and 1 week after training.

Results - Results showed no differences in naming …

Adult And Child Semantic Neighbors Of The Kroll And Potter (1984) Nonobjects, Holly L. Storkel, Suzanne M. Adlof

Faculty Publications

Purpose - The purpose was to determine the number of semantic neighbors, namely semantic set size, for 88 nonobjects (J. F. Kroll & M. C. Potter, 1984) and determine how semantic set size related to other measures and age.

Method - Data were collected from 82 adults and 92 preschool children in a discrete association task. The nonobjects were presented via computer, and participants reported the first word that came to mind that was meaningfully related to the nonobject. Words reported by two or more participants were considered semantic neighbors. The strength of each neighbor was computed as the …

Argument Structure Effects In Action Verb Naming In Static And Dynamic Conditions, Dirk B. Den Ouden, Steve Fix, Todd B. Parrish, Cynthia K. Thompson

Faculty Publications

Argument structure, as in the participant roles entailed within the lexical representation of verbs, affects verb processing. Recent neuroimaging studies show that when verbs are heard or read, the posterior temporoparietal region shows increased activation for verbs with greater versus lesser argument structure complexity, usually bilaterally. In addition, patients with agrammatic aphasia show verb production deficits, graded based on argument structure complexity. In the present study, we used fMRI to examine the neural correlates of verb production in overt action naming conditions. In addition, we tested the differential effects of naming when verbs were presented dynamically in video segments versus …

Neuroimaging And Recovery Of Language In Aphasia, Cynthia K. Thompson, Dirk B. Den Ouden

Faculty Publications

The use of functional neuroimaging techniques has advanced what is known about the neural mechanisms used to support language processing in aphasia resulting from brain damage. This paper highlights recent findings derived from neuroimaging studies focused on neuroplasticity of language networks, the role of the left and right hemispheres in this process, and studies examining how treatment affects the neurobiology of recovery. We point out variability across studies as well as factors related to this variability, and we emphasize challenges that remain for research.

Are Specific Language Impairment And Dyslexia Distinct Disorders?, Hugh W. Catts, Suzanne M. Adlof, Tiffany Hogan, Susan Ellis Weismer

Faculty Publications

Purpose - The purpose of this study was to determine whether specific language impairment (SLI) and dyslexia are distinct developmental disorders.

Method - Study 1 investigated the overlap between SLI identified in kindergarten and dyslexia identified in 2nd, 4th, or 8th grades in a representative sample of 527 children. Study 2 examined phonological processing in a subsample of participants, including 21 children with dyslexia only, and 43 children with SLI only, 18 children with SLI and dyslexia, and 165 children with typical language/reading development. Measures of phonological awareness and nonword repetition were considered.
