The Impact Of Interface Design During An Initial High-Technology Aac Experience: A Collective Case Study Of People With Aphasia, Aimee R. Dietz, Kristy S.E. Weissling, Julie Griffith, Miechelle L. Mckelvey, Devan Macke

Department of Special Education and Communication Disorders: Faculty Publications

The purpose of this collective case study was to describe the communication behaviors of five people with chronic aphasia when they retold personal narratives to an unfamiliar communication partner using four variants of a visual scene display (VSD) interface. The results revealed that spoken language comprised roughly 70% of expressive modality units; variable patterns of use for other modalities emerged. Although inconsistent across participants, several people with aphasia experienced no trouble sources during the retells using VSDs with personally relevant photographs and text boxes. Overall, participants perceived the personally relevant photographs and the text as helpful during the retells. These …

Supporting Narrative Retells For People With Aphasia Using Augmentative And Alternative Communication: 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

Purpose: The purpose of this study was to examine how the interface design of an augmentative and alternative communication (AAC) device influences the communication behaviors of people with aphasia during a narrative retell task.

Method: A case-series design was used. Four narratives were created on an AAC device with combinations of personally relevant (PR) photographs, line drawings (LDs), and text for each participant. The narrative retells were analyzed to describe the expressive modality units (EMUs) used, trouble sources experienced, and whether trouble sources were repaired. The researchers also explored the participants’ perceived helpfulness of the interface features.

Results: The participants …

Facilitation Of Language Acquisition Viewed Through An Interpretative Lens: The Role Of Authenticity, Melanie Ann Harper

Wayne State University Dissertations

A paradigm is the conceptual framework or lens one uses to view reality. The field of speech-language pathology is traditionally rooted in the empirical paradigm, which believes that language can be fragmented into isolated skills and taught in a hierarchal fashion. This belief has resulted in service delivery models that remove students from naturalistic contexts for decontextualized exercises. Progress in language acquisition is measured objectively. The empirical belief is exemplified by the accountability requirements in special education law (e.g., IEP). It is compounded by the realities of public school speech-language pathologists (SLPs), such as high caseload numbers, multiple buildings, and …

Acoustic And Perceptual Measurements Of Prosody Production On The Profiling Elements Of Prosodic Systems In Children By Children With Autism Spectrum Disorders, Joshua John Diehl, Rhea Paul

Communication Disorders Faculty Publications

Prosody production atypicalities are a feature of autism spectrum disorders (ASDs), but behavioral measures of performance have failed to provide detail on the properties of these deficits. We used acoustic measures of prosody to compare children with ASDs to age-matched groups with learning disabilities and typically developing peers. Overall, the group with ASD had longer utterance durations on multiple subtests on a test of prosodic abilities, and both the ASD and learning disabilities groups had higher pitch ranges and pitch variance than the typically developing group on one subtest. Acoustic differences were present even when the prosody was used correctly.These …

Experiences Of Speech-Language Pathology Graduate Students: An Exploratory Phenomenological Study, Anysia J. Ensslen

Theses and Dissertations--Educational Leadership Studies

Within the past decade little research has been conducted in the United States to examine the preparedness of beginning speech-language pathologists; the seminal article used for this research study comes from the United Kingdom (Horton, Byng, Bunning, & Pring, 2004). Literature from the past few decades indicates that there may be deficiencies in the way that beginning speech-language pathologists are being trained clinically.

The review of the literature suggests that the field may lack a clear and broadly supported learning theory or framework for the clinical supervision and training of speech-language pathology graduate students. The literature further supports the importance …

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 …

Q: What are the immediate effects of Modified Melodic Intonation Therapy (MMIT) on the modified repetition and responsive subtests of the Western Aphasia Battery (WAB) in stroke patients with Broca’s aphasia?

While this study had several limitations, the basic premises—the exploration of the effectiveness of changes to traditional MIT and the exploration of treatment in very acute stages—were valuable. Further systematic …

Effects Of Augmentative And Alternative Device On Echolalia In Autism, Cynthia Valenzuela

Open Access Theses & Dissertations

This study was a systematic replication of Mueller and Forbes (n.d.), which evaluated the effects of a high-tech and low-tech augmentative alternative communication (AAC) device on reducing echolalia in a verbal child with autism during conversational speech. The participant for this study was a verbal eleven-year male, who was diagnosed with autism prior to the study. A single subject alternating treatment research design was used to evaluate the effect of a high-tech speech generating AAC device (Proloquo2go) on echolalia. The participant was seen periodically twice a week for two months and periodically for one month. A functional analysis(Prizant & Rydell, …

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 …

Personalizing Aac For People With Aphasia: The Role Of Text And Pictures, Aimee R. Dietz, Kristy S.E. Weissling, Julie Griffith, Miechelle L. Mckelvey

Department of Special Education and Communication Disorders: Faculty Publications

Over time, and with intensive instruction, people with aphasia (PWAs) can learn to use grid-based, categorically organized, high-technology AAC layouts during structured tasks (e.g., Hough & Johnson, 2009). In an effort to reduce the training intensity required to teach PWAs to use AAC; researchers developed visual scene displays (VSDs), designed to complement the residual cognitive and linguistic abilities of PWAs by tapping their intact episodic memory. VSD interfaces incorporate personally relevant (PR) photos, text, and speech output (Dietz, McKelvey, & Beukelman, 2006; Weissling & Beukelman, 2006). VSDs appear to facilitate improved communication success (e.g., McKelvey, Dietz, Hux, Weissling, & Beukelman, …

Neural Underpinnings Of Prosody In Autism, Inge-Marie Eigsti, Jillian Schuh, Einar Mencl, Robert T. Schultz, Rhea Paul

Communication Disorders Faculty Publications

This study examines the processing of prosodic cues to linguistic structure and to affect, drawing on fMRI and behavioral data from 16 high-functioning adolescents with autism spectrum disorders (ASD) and 11 typically developing controls. Stimuli were carefully matched on pitch, intensity, and duration, while varying systematically in conditions of affective prosody (angry versus neutral speech) and grammatical prosody (questions versus statement). To avoid conscious attention to prosody, which normalizes responses in young people with ASD, the implicit comprehension task directed attention to semantic aspects of the stimuli. Results showed that when perceiving prosodic cues, both affective and grammatical, activation of …

Communication-Based Assessment Of Developmental Age For Young Children With Developmental Disabilities, Shari L. Deveney, Lesa Hoffman, Cynthia J. Cress

Special Education and Communication Disorders Faculty Publications

Purpose: In this study, the authors compared a multiple-domain strategy for assessing developmental age of young children with developmental disabilities who were at risk for long-term reliance on augmentative and alternative communication (AAC) with a communication-based strategy composed of receptive language and communication indices that may be less affected by physically challenging tasks than traditional developmental age scores.

Method: Participants were 42 children (age 9–27 months) with developmental disabilities and who were at risk for long-term reliance on AAC. Children were assessed longitudinally in their homes at 3 occasions over 18 months using multiple-domain and communication-based measures. Confirmatory factor analysis …

Spatiotemporal Coupling Of The Tongue In Amyotrophic Lateral Sclerosis, Mili S. Kuruvilla, Jordan R. Green, Yana Yunusova, Kathy Hanford

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The primary aim of the investigation was to identify deficits in spatiotemporal coupling between tongue regions in amyotrophic lateral sclerosis (ALS). The relations between disease-related changes in tongue movement patterns and speech intelligibility were also determined.

Methods: The authors recorded word productions from 11 individuals with ALS with mild, moderate, and severe dysarthria using an x-ray microbeam during word productions. A coupling index based on sliding window covariance was used to determine disease-related changes in the coupling between the tongue regions across each word.

Results: The results indicated decreased spatiotemporal coupling of mid-posterior tongue regions and reduced tongue speed …

Impact Of Noise And Working Memory On Speech Processing In Adults With And Without Adhd, Anne M. P. Michalek

Communication Disorders & Special Education Theses & Dissertations

Auditory processing of speech is influenced by internal (i.e., attention, working memory) and external factors (i.e., background noise, visual information). This study examined the interplay among these factors in individuals with and without ADHD. All participants completed a listening in noise task, two working memory capacity tasks, and two short-term memory tasks. The listening in noise task had both an auditory and an audiovisual condition. Participants included 38 young adults between the ages of 18-35 without ADHD and 25 young adults between the ages of 18-35 with ADHD. Results indicated that diagnosis, modality, and signal-to-noise ratio all have a main …

Sentence Recognition From Articulatory Movements For Silent Speech Interfaces, Jun Wang, Ashok Samal, Jordan R. Green, Frank Rudzicz

Department of Special Education and Communication Disorders: Faculty Publications

Recent research has demonstrated the potential of using an articulation-based silent speech interface for command-and-control systems. Such an interface converts articulation to words that can then drive a text-to-speech synthesizer. In this paper, we have proposed a novel near-time algorithm to recognize whole-sentences from continuous tongue and lip movements. Our goal is to assist persons who are aphonic or have a severe motor speech impairment to produce functional speech using their tongue and lips. Our algorithm was tested using a functional sentence data set collected from ten speakers (3012 utterances). The average accuracy was 94.89% with an average latency of …

Effect Of Parallel Talk On The Language And Interactional Skills Of Preschoolers With Cochlear Implants And Hearing Aids, Sharon A. Raver, Jonna Bobzien, Corrin Richels, Peggy Hester, Anne Michalek, Nicole Anthony

Communication Disorders & Special Education Faculty Publications

Children with profound congenital hearing loss often do not have the same prelinguistic opportunities for social and verbal interaction as their peers with typical hearing [14]. Consequently, language and social skills may be challenging for this group, even after they are provided with amplification or a cochlear implant. This pilot study examined the effectiveness of using a parallel talk intervention to increase the language and interactional skills of three preschoolers with deafnesss. Results revealed that all participants increased verbal turn-taking and that two of the three increased initiated and responded vocal/verbal comments, and initiated and responded nonverbal responses during a …

Augmented Input: The Effect Of Visuographic Supports On The Auditory Comprehension Of People With Chronic Aphasia, Sarah E. Wallace, Aimee R. Dietz, Karen Hux, Kristy S.E. Weissling

Department of Special Education and Communication Disorders: Faculty Publications

Background: Augmented input (AI), or the use of visuographic images and linguistic supports, is a strategy for facilitating the auditory comprehension of people with chronic aphasia. To date, researchers have not systematically evaluated the effects of various types of AI strategies on auditory comprehension.

Aims: The purpose of the study was to perform an initial evaluation of the changes in auditory comprehension accuracy experienced by people with aphasia when they received one type of AI. Specifically, the authors examined the effect four types of non-personalized visuographic image conditions on the comprehension of people with aphasia when listening to narratives.

Adapted Stories: Creating Accessible Stories For Children With Complex Language Problems, Janet L. Dodd

Communication Sciences and Disorders Faculty Articles and Research

Many children with autism spectrum and other language impairing disorders present with complicated language problems (CLP; Franke & Durbin, 2011). These children exhibit delays across multiple domains of language and often benefit from narrative- and story-based interventions. However, many children’s stories—the vehicle often employed for these types of interventions—are often too complex for them. The purpose of this article is to introduce a strategy for making stories accessible, linguistically and cognitively, for children with CLP.

Rural Speech-Language Pathologists' Perceptions And Knowledge Of Emergent Literacy Instructional Practices: A Mixed Methods Study, Kellie C. Ellis

Theses and Dissertations--Rehabilitation Sciences

The acquisition of emergent literacy skills has become a prominent focus of early childhood education programs in recent years as research has demonstrated the significance of emergent literacy ability in the process of learning to read. The effectiveness of use of varied instructional techniques targeting the emergent literacy domains of phonological awareness, written language awareness, emergent writing, and oral language is well described in the literature. Consequently, educational service providers like speech-language pathologists are being called upon to assume roles in emergent literacy service provision. However, research has not fully explored the perceptions and knowledge speech-language pathologists possess of emergent …

Sensitivity To Probabilistic Orthographic Cues To Lexical Stress In Adolescent Speakers With Autism Spectrum Disorder And Typical Peers, Joanne Arciuli, Rhea Paul

Communication Disorders Faculty Publications

Lexical stress refers to the opposition of strong and weak syllables within polysyllabic words and is a core feature of the English prosodic system. There are probabilistic cues to lexical stress present in English orthography. For example, most disyllabic English words ending with the letters “-ure” have first-syllable stress (e.g., “pasture”, but note words such as “endure”), whereas most ending with “-ose” have second-syllable stress (e.g., “propose”, but note examples such as “glucose”). Adult native speakers of English are sensitive to these probabilities during silent reading. During testing, they tend to assign first-syllable stress when reading a nonword such as …

Bridging The Research Gap: Making Hri Useful To Individuals With Autism, Elizabeth Kim, Rhea Paul, Frederick Shic, Brian Scassellati

Communication Disorders Faculty Publications

While there is a rich history of studies involving robots and individuals with autism spectrum disorders (ASD), few of these studies have made substantial impact in the clinical research community. In this paper we first examine how differences in approach, study design, evaluation, and publication practices have hindered uptake of these research results. Based on ten years of collaboration, we suggest a set of design principles that satisfy the needs (both academic and cultural) of both the robotics and clinical autism research communities. Using these principles, we present a study that demonstrates a quantitatively measured improvement in human-human social interaction …

Endoscopic And Stroboscopic Presentation Of The Larynx In Male-To-Female Transsexual Persons, Derek Palmer, Angela M. Dietsch, Jeff Searl

Department of Special Education and Communication Disorders: Faculty Publications

Background. Male-to-female transsexual (MFT) persons often attempt to produce a female-sounding voice as part of the transition process. Endoscopic and stroboscopic data about how they accomplish this with an anatomically male larynx are lacking.

Objectives. To describe vocal fold activity in MFT persons producing their feminine voice and identify signs of vocal misuse or hyperfunction in MFT speakers, if any.

Study Design. Prospective, nonrandomized, descriptive study of a convenience sample of MFT persons.

Methods. All MFT persons had endoscopic and stroboscopic procedures completed. Images were rated on a range of parameters by two experienced voice therapists …

Quantifying Articulatory Distinctiveness Of Vowels, Jun Wang, Jordan R. Green, Ashok Samal, David B. Marx

Department of Special Education and Communication Disorders: Faculty Publications

The articulatory distinctiveness among vowels has been frequently characterized descriptively based on tongue height and front-back position; however, very few empirical methods have been proposed to characterize vowels based on time-varying articulatory characteristics. Such information is not only needed to improve knowledge about the articulation of vowels but also to determine the contribution of articulatory imprecision to poor speech intelligibility. In this paper, a novel statistical shape analysis was used to derive a vowel space that depicted the quantified articulatory distinctiveness among vowels based on tongue and lip movements. The effectiveness of the approach was supported by vowel classification accuracy …

Augmentative And Alternative Communication Systems In The Classroom, Helen Angela Mezzomo

Walden Dissertations and Doctoral Studies

Augmentative-alternative communication (AAC) systems are used to give voice to individuals who are nonverbal. As AAC systems become more complex and prevalent in the classroom expectations of school-based professionals expand. However, the roles of those expected to support AAC systems, primarily teachers and speech-language pathologists (SLPs), are not clearly defined. Without clearly defined roles, professionals may not provide needed support to students who use AAC. Dewey's theory of community suggests that role confusion leads to insufficient and ineffective services. The purpose of this cross-sectional quantitative study was to determine how teachers and SLPs view their roles in supporting AAC. The …
