Maximizing Audibility And Speech Recognition With Non-Linear Frequency Compression By Estimating Audible Bandwidth, Ryan W. Mccreery, Marc A. Brennan, Brenda Hoover, Judy Kopun, Patricia G. Stelmachowicz

Department of Special Education and Communication Disorders: Faculty Publications

Objective—Nonlinear frequency compression attempts to restore high-frequency audibility by lowering high-frequency input signals. Methods of determining the optimal parameters that maximize speech understanding have not been evaluated. The effect of maximizing the audible bandwidth on speech recognition for a group of listeners with normal hearing is described.

Design—Nonword recognition was measured with twenty normal-hearing adults. Three audiograms with different high-frequency thresholds were used to create conditions with varying high-frequency audibility. Bandwidth was manipulated using three conditions for each audiogram: conventional processing, the manufacturer’s default compression parameters, and compression parameters that optimized bandwidth.

Results—Nonlinear frequency compression optimized to provide the widest …

Effects Of Body Position And Sex Group On Tongue Pressure Generation, Angela M. Dietsch, Carmen M. Cirstea, Ed T. Auer, Jeff P. Searl

Department of Special Education and Communication Disorders: Faculty Publications

Fine control of orofacial musculature is necessary to precisely accelerate and decelerate the articulators across exact distances for functional speech and coordinated swallows (Amerman & Parnell, 1990; Benjamin, 1997; Kent, Duffy, Slama, Kent, & Clift, 2001). Enhanced understanding of neural control for such movements could clarify the nature of and potential remediation for some dysarthrias and other orofacial myofunctional impairments. Numerous studies have measured orolingual force and accuracy during speech and nonspeech tasks, but have focused on young adults, maximum linguapalatal pressures, and upright positioning (O’Day, Frank, Montgomery, Nichols, & McDade, 2005; Solomon & Munson, 2004; Somodi, Robin, & Luschei, …

Therapeutic Alliance Between Youth And Staff In Residential Group Care: Psychometrics Of The Therapeutic Alliance Quality Scale, Kristin Duppong-Hurley, Matthew C. Lambert, Mark Van Ryzin, Justin Sullivan, Amy Stevens

Department of Special Education and Communication Disorders: Faculty Publications

Therapeutic alliance has been frequently studied in individual counseling sessions; however, research on therapeutic alliance in residential settings for youth with mental health diagnoses has been limited. This may be due, in part, to the presence of multiple service providers often in caregiving roles. The purpose of this study was to examine the psychometric quality of a widely utilized measure of therapeutic alliance used in psychotherapy with youth in residential care where the treatment is provided by a trained married couple. We also compared the relationship between youth ratings of their male and female service provider, as well as examined …

Supporting Narrative Retells For People With Aphasia Using Aac: Photographs Or Line Drawings? Text Or No Text?, Julie Griffith, Aimee R. Dietz, Kristy S.E. Weissling

Department of Special Education and Communication Disorders: Faculty Publications

People with aphasia (PWAs) have demonstrated the ability to learn augmentative and alternative communication (AAC) devices that employ traditional grid layouts to enhance their communication; however, the process is typically lengthy and yields limited generalization (Fox & Fried-Oken, 2001; Koul & Harding, 1998). In response, researchers have begun to investigate the use of visual scene displays (VSDs) to support the communication interactions of PWAs by capitalizing on their relatively intact episodic memory (Beukelman, Dietz, McKelvey, Hux, & Weissling, in press; Dietz, Beukelman, & McKelvey, 2006a; Dietz, McKelvey, Beukelman, Weissling, & Hux, 2006b; McKelvey, Dietz, Hux, Weissling, & Beukelman, 2007). High-technology …

Electropalatography As An Adjunct To Nonspeech Orofacial Myofunctional Disorder Assessments: A Feasibility Study, Alana Mantie-Kozlowski, Kevin M. Pitt

Department of Special Education and Communication Disorders: Faculty Publications

The purpose of this study was to determine if electropalatography (EPG) would be a useful adjunct and feasible option for those conducting clinical assessments of individuals with suspected nonspeech orofacial myofunctional disorders (NSOMD). Three females (two adults, one child) were referred by their orthodontist for assessment of suspected NSOMD. Three adults and one child without NSOMD were recruited for the purpose of evaluating methodological construct, and to provide comparisons for participants with NSOMD. Using EPG, lingual-palatal timing and contact patterns of 105 saliva swallows (45 with NSOMD, 60 without NSOMD) were analyzed by compartmentalizing the sensor display and tracking the …

Examining Inclusive Practices In Nicaraguan Schools, Julie Delkamiller, Kristine D. Swain, Elizabeth M. Leader-Janssen, Mitzi J. Ritzman

Special Education and Communication Disorders Faculty Publications

The purpose of this study was to examine Nicaraguan teachers’ efficacy for inclusive practices and current teaching practices in Nicaraguan schools as the first step in developing a special education training program. Sixty-one teachers in 15 schools completed the Teacher Efficacy of Inclusive Practice (TEIP) survey to determine their confidence in inclusive practices, collaboration and dealing with disruptive behaviors. Classroom observations were also completed to examine the environment, teaching/ learning strategies, student behaviors, learning materials, and time distribution in the classroom. Results from the TEIP indicated Nicaraguan teachers were highly efficacious in inclusive practices. The survey and observation data collected …

Evaluating The Phonology Of Nicaraguan Sign Language: Preprimer And Primer Dolch Words, Julie Delkamiller

Special Education and Communication Disorders Faculty Publications

Over the past 30-years linguists have been witnessing the birth and evolution of a language, Idioma de Señas de Nicaragua (ISN), in Nicaragua, and have initiated and documented the syntax and grammar of this new language. Research is only beginning to emerge on the implications of ISN on the education of deaf/hard of hearing children in Nicaragua. The purpose of this comparative exploratory field study was to evaluate preprimer and primer Dolch sight words and sign language frequency between English, American Sign Language (ASL), Spanish and Idioma de Señas de Nicaragua (ISN). The research focused on word and sign frequencies …

Video Self-Modeling On An Ipad To Teach Functional Math Skills To Adolescents With Autism And Intellectual Disability, Cami Elizabeth Burton, Darlene Anderson, Mary Anne Prater, Tina Taylor

Faculty Publications

Research suggests that video-based interventions can provide increased opportunity for students with disabilities to acquire important academic and functional skills; however, little research exists regarding video-based interventions on the academic skills of students with autism and intellectual disabilities. The current study used a multiple baseline design across participants to investigate the effects of video self-modeling (VSM) on the mathematics skill acquisition of adolescents with autism. Four adolescent male students viewed videos of themselves on an iPad solving mathematical problems to estimate the amount of money used to pay for a given item and the amount to receive in change. Findings …
