Dual-Task Interference: The Effects Of Verbal Cognitive Tasks On Upright Postural Stability In Parkinson's Disease, J. D. Holmes, M. E. Jenkins, Andrew M. Johnson, S. G. Adams, S. J. Spaulding

Occupational Therapy Publications

Although dual-task interference has previously been demonstrated to have a significant effect on postural control among individuals with Parkinson's disease, the impact of speech complexity on postural control has not been demonstrated using quantitative biomechanical measures. The postural stability of twelve participants with idiopathic Parkinson's disease and twelve healthy age-matched controls was evaluated under three conditions: (1) without a secondary task, (2) performing a rote repetition task and (3) generating a monologue. Results suggested a significant effect of cognitive load on biomechanical parameters of postural stability. Although both groups increased their postural excursion, individuals with Parkinson's disease demonstrated significantly reduced …

The Effects Of Peer Training Social Intervention On Social Interactions Of Children With Autism, Mindy Leigh Krebs

Student Theses and Dissertations

This study investigated the effects of a peer training intervention on social interactions among two subjects with autism spectrum disorder (ASD) and four typically developing peers. A multiple probe (Horner & Baer, 1978) across tasks, replicated across participants design, was used to evaluate these effects. Prior to data collection, a task sequence analysis was created to identify and describe the specific behavioral steps and sequence needed for successful acquisition of attention maintenance. Sub-behaviors selected for acquisition included: 1) maintaining eye contact or directional gaze; 2) maintaining close proximity to peer while interacting; 3) directing or initiating conversation with the peer; …

Considerations For Test Selection: How Do Validity And Reliability Impact Diagnostic, Jennifer C. Friberg

Faculty Publications – Communication Sciences and Disorders

Nine preschool and school-age language assessment tools found to have acceptable levels of identification accuracy were evaluated to determine their overall levels of psychometric validity for use in diagnosing the presence/absence of language impairment. Eleven specific criteria based on those initially devised by McCauley and Swisher (1984) were applied to each of the selected tests in order to determine each test’s overall level of psychometric validity. Results indicated that each of the selected assessment tools met at least eight of the 11 criteria used to evaluate each assessment tool. Five tests met 10 out of 11 criteria. Findings are discussed …

A pretest - posttest control group design was used to compare the effectiveness of phonological awareness intervention and visual phonics in promoting the development of the following emergent literacy skills: alphabet knowledge, beginning sound awareness, print awareness, rhyme awareness, nursery rhyme awareness, phonological awareness at the syllable level, and name writing abilities. Three groups were formed from twenty-four subjects from at-risk early childhood programs in central Illinois. The …

The Effect Of Person Versus Aac Directed Apraxia Therapy On Elicited Imitation For Children With Autism Spectrum Disorder, Jeanna Rachelle Probst

Masters Theses

There is limited research in the area of Augmentative and Alternative Communication (AAC) and autism spectrum disorder with childhood apraxia of speech. The current research project was designed to evaluate the amount of elicited imitation produced when using a person-directed stimulus mode versus an AAC-directed stimulus mode. The dependent variable was elicited imitations. The independent variables were the AAC-directed condition and the person-directed condition.

The subjects were six school-aged children with the diagnosis of Autism Spectrum Disorder (ASD) and Childhood Apraxia of Speech (CAS). The subjects were pulled out of their regular 45 minute individual speech therapy and randomly presented …

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 …

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 …

Age Effect On The Gaze Stabilization Test, Julie A. Honaker

Department of Special Education and Communication Disorders: Faculty Publications

Impairments of the vestibular-ocular reflex (VOR) lead to a decline in visual acuity during head movements. Dynamic visual acuity (DVA) testing is a sensitive assessment tool for detecting VOR impairments. DVA evaluates accuracy of visual acuity during fixed velocity head movements. In contrast, the Gaze Stabilization test (GST) is a new functional evaluation of the VOR that identifies a person’s maximum head velocity (in degrees per second) a person can maintain with stable vision of a target (i.e. optotype). The objective of this study was to evaluate the effect of age on the GST in participants without vestibular disease. The …

Vowel Recognition From Continuous Articulatory Movements For Speaker-Dependent Applications, Jun Wang, Jordan R. Green, Ashok Samal, Tom D. Carrell

Department of Special Education and Communication Disorders: Faculty Publications

A novel approach was developed to recognize vowels from continuous tongue and lip movements. Vowels were classified based on movement patterns (rather than on derived articulatory features, e.g., lip opening) using a machine learning approach. Recognition accuracy on a single-speaker dataset was 94.02% with a very short latency. Recognition accuracy was better for high vowels than for low vowels. This finding parallels previous empirical findings on tongue movements during vowels. The recognition algorithm was then used to drive an articulation-to-acoustics synthesizer. The synthesizer recognizes vowels from continuous input stream of tongue and lip movements and plays the corresponding sound samples …

Visual Phonics And Phonological Awareness Interventions: Stability Of Gains In Language And Literacy, Mara Hampton

Undergraduate Honors Theses

The current study was a follow-up to a pretest-posttest control group experiment that found speech and/or language impaired preschoolers significantly improved their receptive and expressive language skills after ten weeks of phonological awareness interventions. Following ten weeks of phonological awareness intervention, speech and/or language impaired preschoolers also made gains in early literacy skills, with greater gains in a phonological awareness group supplemented by See the Sound/Visual Phonics (visual phonics).

The present study was conducted as a follow-up six months later. The purpose was to determine the stability of gains from the two phonological awareness interventions on the development of auditory …

Increasing Written Language Skills Utilizing Writing Software And Traditional Methods, Caroline Larson

Undergraduate Honors Theses

A grid based computer program, Clicker5, appeared to have many features that logically may assist struggling writers. It utilizes pictures, sound, speech synthesis, word banks and a spelling checker. Karemaker et al. (2008) examined the use of Clicker5 and observed increased attention and focus during reading, and greater gains in word recognition and rhyme awareness. Scattered research exists on some of the multimedia features that Clicker5 utilizes (e.g. auditory and visual instruction, specific feedback, student specific examples, Wissick & Gardner, 2000; composition processes and revision facilitation, MacArthur 2000; spell checkers with strategy instruction, and speech synthesis to increase error …

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 …

Investigation Of A Classroom-Based Reading Intervention Strategy For Older Elementary Students With Poor Decoding Skills, Shara Brinkley

LSU Doctoral Dissertations

Using a response to intervention framework, this study investigates the efficacy of a classroom-based intervention for struggling readers with decoding deficits in the upper elementary grades. Twenty two students in the fourth and sixth grades from four classrooms in low-performing schools received either a short 20-minute intervention delivered by their teacher or access to the lessons for an equivalent amount of time but no teacher instruction. Using three orthographic patterns, the 24 lessons consisted of a series of ten minimally contrasted words differing by one letter. The students in the experimental group decoded the words using a visual alphabet (Phonic …

Thinking Outside Of The Assessment Box: Assessing Social Communicative Functioning In Students With Asd, Janet L. Dodd

Communication Sciences and Disorders Faculty Articles and Research

The assessment of a student suspected of an autism spectrum disorder (ASD) diagnosis requires the integration of information collected by a variety of professionals across various domains of functioning. One of the core deficits of students with ASD is a deficit related to social communicative competence (SCC). SCC requires the integration of language, social cognition, and higher order executive functions (Coggins, Olswang, Carmichael Olsson, & Timler, 2003) This article will propose an assessment model of social communicative functioning that was developed based on the SCC framework of Coggins and colleagues as a component of the Comprehensive Multidisciplinary Assessment Protocols for …
