Outcomes Of An Emotion Word Intervention For Children With Social Communication Impairments, Rebecca Cloward Mansfield

Theses and Dissertations

Children with social communication disorders have been found to exhibit deficits in emotional intelligence, including the ability to identify emotions attributed to facial expressions. The purpose of this thesis was to examine the efficacy of a social communication intervention program designed to increase the accuracy of emotion based word use in three elementary school-aged participants with social communication disorders. The participants took part in a multiple-baseline, 20-session treatment including story enactment, journaling procedures, and supplementary activities. The story enactment portion of the intervention centered on Mercer Mayer's A Boy, A Dog, and A Frog (1967) wordless picture book series. Participants' …

Word-Finding Difficulties: Exploring Tip-Of-The-Tongue States In Young And Old Adults, Allison J. Partridge

Electronic Thesis and Dissertation Repository

A Tip-of-the-Tongue (TOT) occurs when you are trying to think of a specific word but lack the ability to bring it to mind. The present study examined implicit learning processes operating under errorful (20-second delay) or errorless (0-second delay) learning conditions in TOT states. Participants included 15 young (20-30 years) and 15 old (65-88 years) adults who were tested twice a week for four weeks on a definition-word pair task. For young participants, results indicated that a TOT was more likely and older participants were more likely to indicate they did not know the word on a consecutive session after …

The goal of this research was to identify areas of strength and need in the academic abilities of students with high functioning autism spectrum disorder (HFASD).

Three studies were undertaken: 1) six meta-analyses investigated whether nonverbal IQ was in accordance with academic achievement scores in the areas of reading, writing, and math for students with HFASD; 2) the narrative writing skills of students with HFASD were examined in order to describe the ways their writing may differ from their typically developing (TD) peers; and 3) the persuasive writing of students with HFASD was examined to determine whether their texts resembled …

Narratives By Six Year Old And Nine Year Old Boys: Brute: Institutional, And Non-Institutional Mental Facts, Adam Craig Whipple

Master's Theses

Brute facts, institutional facts, and non-institutional mental facts were studied. The philosophy of constructionism and the theory of intent provided a framework for this research. Intentionality provided the basis for social facts. Brute, institutional, and noninstitutional mental facts were operationally defined. This study analyzed the use of these facts in the narratives of 6-year-old boys and 9-year-old boys. There were a total of 19 participants in this research. This research established brute, institutional, and non-institutional mental facts as appropriate operational categories for studying children's narratives. The 6-year-old boys produced more brute facts than the 9-year-old boys. The 9-year-old boys produced …

Brain Mapping Of The Mismatch Negativity Response To Vowel Variances Of Natural And Synthetic Phonemes, Lyndsy Marie Smith

Theses and Dissertations

The mismatch negativity (MMN) is a specific event-related potential (ERP) component used frequently in the observation of auditory processing. The MMN is elicited by a deviant stimulus randomly presented in the presence of repeating stimuli. The current study utilized the MMN response in order to determine the temporal (timing) and linguistic processing of natural and synthetic vowel stimuli. It was hypothesized that a significant MMN response would be elicited by natural and synthetic vowel stimuli. Brain mapping of the MMN response was hypothesized to yield temporal resolution information, which would provide detail regarding the sequential processing differences between natural and …

A Boot Camp Approach To Remediating Interdental /S/ In A School-Aged Child, Melanie Ellen Peris

Theses and Dissertations

The relationship between speech articulation therapy dose (frequency, intensity, duration) and treatment outcomes are poorly understood. Identifying optimal therapy doses for specific articulation disorders is essential to providing efficient clinical care. Recent research indicates that intensive speech therapy doses-known as boot camps-may promote rapid improvement and generalization for certain speech disorders. Therefore the present investigation examined the effects of a boot camp speech therapy approach to remediate interdental /s/ production in an 8-year-old male. The boot camp included two days of speech therapy involving visual, tactile, and auditory feedback approaches. Therapy was administered 5.5 hours per day across morning and …

Dual-Task Effects Of Walking On Rate Of Speech, Dayna Kathleen Jablecki

Electronic Thesis and Dissertation Repository

The dual-task effect of walking on rate of speech was measured in 32 healthy young adults. The influence of word meaning and sex on rate of speech was also investigated. A separate inspection time task was used to determine whether speed of information processing (SIP), predicted the degree of dual-task interference of walking on rate of speech. This study revealed that rate of speech was influenced by dual-task interference effects due to the performance of a simultaneous gait task. Pause times suggested a sex effect, demonstrating that while walking, women spent significantly less time pausing between verbal stimuli than men. …

Effects Of Hearing Aid Amplification On Robust Neural Coding Of Speech, Jonathan Daniel Boley

Open Access Dissertations

Hearing aids are able to restore some hearing abilities for people with auditory impairments, but background noise remains a significant problem. Unfortunately, we know very little about how speech is encoded in the auditory system, particularly in impaired systems with prosthetic amplifiers. There is growing evidence that relative timing in the neural signals (known as spatiotemporal coding) is important for speech perception, but there is little research that relates spatiotemporal coding and hearing aid amplification.

This research uses a combination of computational modeling and physiological experiments to characterize how hearing aids affect vowel coding in noise at the level of …

Developing A Drug Delivery System For Treatment Of Vocal Fold Scarring, Aaron Michael Kosinski

Open Access Dissertations

Vocal fold scarring is an affliction that results in the formation of a disorganized and stiff extracellular matrix (ECM) with abnormal ECM component densities & structures including a significant increase in collagen deposition. It is caused by improper healing post injury and results in profound changes in the biomechanical properties of the vocal folds impairing their ability to generate a normal mucosal wave during phonation.

Finding an effective treatment for vocal fold scarring has been elusive. Currently, treatments seek temporary solutions that correct glottal incompetence and reduce stiffness caused by the scar through the augmentation of the vocal folds using …

Predicting Language Impairment Status: A Risk Factor Model, Johanna Maria Rudolph

Open Access Dissertations

The etiology of specific language impairment (SLI) is multifactorial. Research has shown that genetic, environmental, and developmental factors may influence the course of its development. Because many of these factors are present even before a child is born, it is possible that a child's risk of developing the disorder can be identified long before grammatical deficits are observed. The goal of this study was to develop and validate a screening tool to discriminate between children with SLI and typically developing (TD) children using risk factor information including gender, family history of communication or reading disorders, socioeconomic status, maternal and paternal …

Neural Encoding Of Complex Signals In The Healthy And Impaired Auditory Systems, Saradha Ananthakrishnan

Open Access Dissertations

Individuals with sensorineural hearing loss (SNHL) typically experience difficulty in understanding speech. Our current knowledge of deficits in speech perception and encoding consequent to SNHL is restricted to psychophysical studies in humans and single-unit experiments in animals. However, the nature of degradation in neural encoding of speech following hearing impairment in humans has not been extensively researched. The objective of this dissertation is to provide a systematic evaluation of neurobiological signature of hearing loss at the subcortical level using an objective electrophysiological non-invasive neural index, the frequency following response (FFR). Subcortical neural encoding of speech signals is explored by quantifying …

Treatment Of Foundational Reading Skills Through Telepractice And Face-To-Face Environments: Single Subject Design, Mary Beth Hetherton

Open Access Dissertations

Service delivery and the access to specialized instructions to consumers, encounters many barriers within the profession of speech-language pathology. This state of affairs is largely due to the disparate distribution of speech language services (ASHA, 2005). This restricted access, or an inability to access services, is a result of a number of factors, which include lack of clinicians, insufficient number of facilities in geographic area, and transportation issues (ASHA, 2004e). As a result, students who require specialized reading instruction are not afforded the opportunity to access the necessary treatment. It is essential that the literacy needs of all children be …

Investigation Of Auditory Encoding And The Use Of Auditory Feedback During Speech Production, Laura E. Beamish

Electronic Thesis and Dissertation Repository

Responses to altered auditory feedback during speech production are highly variable. The extent to which auditory encoding influences this varied use is not well understood. Thirty-nine normal hearing adults completed a first formant (F1) manipulation paradigm where F1 of the vowel /ε/ was shifted upwards in frequency towards an /æ/–like vowel in real-time. Frequency following responses (FFRs) and envelope following responses (EFRs) were used to measure neuronal activity to the same vowels produced by the participant and a prototypical talker. Cochlear tuning, measured by SFOAEs and a psychophysical method, was also recorded. Results showed that average F1 production changed to …

Auditory Temporal Processing In Children With Specific Language Impairment Compared To Same-Age Controls, Elaine Yuen Ling Kwok

Electronic Thesis and Dissertation Repository

It has been proposed that impaired language development in children with Specific Language Impairment (SLI) originates from immature auditory temporal integration (ATI), but results are inconsistent. We compared electroencephalographic data from 25 children with SLI aged 6-11 years to 25 typically developing peers. Participants’ neural responses to a 50ms tone presented alone were compared to their responses to two tones separated by silent gaps of 100, 200, 300 or 400ms. Amplitude and latency of P1 and N2 responses to single tones and tone pairs were compared across groups and gap conditions. The groups did not differ in the amplitude or …

Relationship Between A Measure Of Social And Emotional Development And Early Communication Development In Young Children With Cleft Palate, Jenna L. Pugh

Electronic Theses and Dissertations

This study was an examination of responses to a standardized assessment of social-emotional behaviors and correlation with speech and language development in young children with cleft palate and/or lip. Twenty-eight participants aged 14-35 months with nonsyndromic cleft palate and or lip were included in this study. The Infant-Toddler Social and Emotional Assessment (ITSEA) was used to identify emerging social and emotional behaviors. Descriptive analysis of ITSEA results was completed. Pearson correlation coefficient and effect size estimates were calculated between ITSEA domain raw scores and measures of speech and language development. A small proportion of participants (14%) showed ITSEA scores beyond …

The Role Of The Vestibular And Proprioceptive Systems In Processing Dynamic Sound Localization Cues, Janet Kim

Electronic Thesis and Dissertation Repository

Head movements are known to be beneficial during sound localization because the auditory system can integrate the dynamic cues generated by head movement while maintaining a spatial representation of the position and orientation of the head-in-space. To measure the extent to which vestibular and proprioceptive cues influence processing of dynamic sound localization cues resulting from head rotation, we measured the ability of normally hearing listeners to localize front/back sources of low-frequency sounds while the two modalities were individually or congruently stimulated. Targets were presented over headphones during head rotations using virtual auditory space methods. Dynamic localization cues corresponded to head-in-space …

A Comparison Of Speech Amplification Devices For Individuals With Parkinson's Disease And Hypophonia, Monika Andreetta

Electronic Thesis and Dissertation Repository

One of the most prevalent speech impairments in idiopathic Parkinson’s disease (PD) is hypophonia, a reduction in intensity, which typically decreases intelligibility. Speech amplification devices are a potential solution; however, despite the availability of a broad range of devices, no previous studies systematically compare their efficacy in PD. This study examined the effects of speech task (Sentence Intelligibility Test versus conversation), background noise (no noise versus 65 dB SPL multi-talker noise), and selected devices (ADDvox, BoomVox, ChatterVox, Oticon, SoniVox, Spokeman, and Voicette) for 11 PD and 10 control participants, using outcome measures of speech intensity, speech-to-noise ratio, intelligibility, sound quality, …

Parents engaged their children in interactions within hands-on activities designed to teach specific literacy skills as part of a kindergarten project entitled Systematic and Engaging Early Literacy (SEEL). Data for this study were extracted from audio and video recordings of parent-child interactions during three targeted literacy activities. Specialized software (LENA Pro) was used to analyze the interactions regarding adult and child use of targeted words (word count) and turn taking. To gain additional information about the exchanges, …

Language Contributions To Health Related Quality Of Life In Amyotrophic Lateral Sclerosis, Katie M. Findlater

Electronic Thesis and Dissertation Repository

Concurrent with the well-documented motor speech production impairments in amyotrophic lateral sclerosis (ALS), individuals with ALS exhibit language problems including confrontation and generative naming difficulties, single word auditory and reading comprehension problems, and decreased self-regulation based on fewer self-corrected utterances, among other language disruptions. Health related quality of life (HRQoL) measures specific to ALS often contain items related to its characteristic speech production problems that are thought to influence overall quality of life. However, the language problems in ALS are rarely if ever considered within the context of HRQoL. The current study aimed to identify the relationship between language problems …

Social Networks Of Children With Language Impairment, Serena Marita Louisa Mickelson

Theses and Dissertations

Children with language impairment (LI) often exhibit social difficulties along with language issues that can affect their friendships with peers. This study sought to identify the self-reported social networks of children with LI and compare them to the self-reported social networks of children with typical language development. Sixteen children with LI (9 girls and 7 boys) between the ages of 5-11 years, and sixteen children with typical language development matched for age and gender were studied. Children were asked to name interactants in four social circles (Blackstone & Hunt Berg, 2003): family, friends, acquaintances, and paid interactants. A parent also …

Effect Of Concurrent Walking And Interlocutor Distance On Conversational Speech Intensity And Rate In Parkinson's Disease, Cassandra M. Mccaig

Electronic Thesis and Dissertation Repository

This study examined the effects of concurrent walking tasks and interlocutor distance on conversational speech production in fifteen individuals with idiopathic Parkinson’s disease (PD) and fourteen age-equivalent controls. Recent studies of speech in PD have demonstrated that changes in the behavioural conditions and the environmental context can have a powerful effect on the severity of speech symptoms in PD. This investigation focused on changes in speech intensity and speech rate in response to changes in walking speed and interlocutor distance. Results suggest that the introduction of a concurrent walking task significantly increased the conversational speech intensity of both controls and …

The Effect Of Age On Speech Motor Performance During Divided Attention, Dallin J. Bailey

Theses and Dissertations

The present study examined the divided attention effects of three non-speech tasks on concurrent speech motor performance. These tasks targeted linguistic, cognitive, and manual motor activity. Participants included 60 healthy adults separated into three different age groups of twenty participants each: college-age (20s), middle-aged (40s), and older adults (60s). Each participant completed a speech task once in isolation and once concurrently with each of the three non-speech tasks: a semantic decision task, a quantitative comparison task, and a manual motor task. The non-speech tasks were also performed in isolation. The speech task involved repeating a target phrase each time a …

The Effects Of Emotion On Acoustic Characteristics Of Vocal Vibrato In Trained Singers, Sharee Oakes Holmes

Theses and Dissertations

The purpose of this study was to investigate the effects of emotion on several key acoustic features of vibrato including vibrato rate, extent, and steadiness (measured by FM rate COV and FM extent COV). We hypothesized that intensity of emotion would have a significant effect on vibrato rate, extent, and periodicity, although the direction of these changes was undetermined. There were 10 participants, including eight females and two males, who were graduate student singers with high competency ratings. Each participant completed a series of tasks including sustained vowels at several pitch and loudness levels, an assigned song that was determined …

Automated Identification Of Relative Clauses In Child Language Samples, Erika E. Ehlert

Theses and Dissertations

Relative clauses are grammatical constructions that are of relevance in both typical and impaired language development. Thus, the accurate identification of these structures in child language samples is clinically important. In recent years, computer software has been used to assist in the automated analysis of clinical language samples. However, this software has had only limited success when attempting to identify relative clauses. The present study explores the development and clinical importance of relative clauses and investigates the accuracy of the software used for automated identification of these structures. Two separate collections of language samples were used. The first collection included …

Brain Imaging Of Event Related Potentials In Children With Language Impairment, Hillary Ann Benton

Theses and Dissertations

Event related potentials (ERPs) may provide specific information about how particular aspects of language are processed by the brain over time. This study investigated the electrophysiology of language processing in two children with language impairment (LI) when compared to five typically developing children. The N400, P600, and the early left anterior negativity (ELAN) were analyzed after participants listened to linguistically correct, syntactically incorrect, and semantically incorrect sentences. Participants were instructed to indicate whether the sentences were correct or incorrect. Latency and amplitude of the ERP components were compared between the two groups of participants and sentence types. Results from the …

The Effectiveness Of Using Electropalatography To Remediate A Developmental Speech Sound Disorder In A School-Aged Child With Hearing Impairment, Kristina Lynne Pickett

Theses and Dissertations

Advances in instrumentation and computer technology such as electropalatography (EPG) have offered additional types of feedback to more traditional therapy for individuals with speech disorders, specifically those with hearing impairment. The purpose of this study was to document whether therapeutic integration of EPG visual feedback in combination with traditional articulation therapy for a school-aged child with an articulation disorder secondary to hearing impairment was more effective than traditional therapy alone. One participant received five sessions of each therapy approach. Six adult listeners rated the quality of the participant's production of /r/ in words recorded during the therapy sessions. The EPG …

A Preliminary Study Of The Articulatory And Acoustic Features Of Forward And Backward Tone Placement In Singing, Krista Wyllys

Masters Theses

A variety of terms exist for describing tone quality in singing, and voice scientists, voice therapists, teachers of singing, and students of singing use different terms to describe the same sound. One aspect of tone quality is tone placement. Teachers of singing often rely on imagery and imitation to elicit correct tone placement from students of singing. More concrete data about what produces forward and backward tone placement could supplement singing teachers’ current practice of using imagery and imitation to elicit a desirable tone quality. This study examined forward and backward tone placement to determine the articulatory gestures and acoustic …

Executive Functions And Social Interactions: Developing Social Scenarios, Mackenzie Waite

Masters Theses

The aim of this study was to develop a series of vignettes to form the basis for an assessment of executive functions (EFs) for 9 – 12 year old children. Although EFs are necessary for effective social communication and positive social interactions, currently, most EF assessments focus on impersonal activities. Little research exists that incorporates real-time processing using ecologically valid social scenarios. The current study aims to develop realistic scenarios that children could encounter in daily life. Ethnographic interviews were conducted with six participants, who worked in a school with 9-12 year old children, to gain their perspective on social …
