The interviews and scales explored the potential impact of BCI-AAC, along with barriers and solutions to BCI-AAC implementation. Speech-language pathologists estimated that 1.5% to 50% of their caseload may benefit from BCI-AAC across various settings. Further, identified barriers and solutions included (a) BCI-AAC implementation …

Strategies For Highlighting Items Within Visual Scene Displays To Support Augmentative And Alternative Communication Access For Those With Physical Impairments, Kevin Pitt, John W. Mccarthy

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: In contrast to the traditional grid-based display, visual scene displays (VSDs) offer a new paradigm for aided communication. For individuals who cannot select items from an AAC display by direct selection due to physical impairments, AAC access can be supported via methods such as item scanning. Item scanning sequentially highlights items on a display until the individual signals for selection. How items are highlighted or scanned for AAC access can impact performance outcomes. Further, the effectiveness of a VSD interface may be enhanced through consultation with experts in visual communication. Therefore, to support AAC access for those with physical …

Neurobehavioral Correlates Associated With Melodic Intonation Therapy For Adults With Nonfluent Aphasia, Caitlin Norquist

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Recent trends in neuroimaging, as it relates to the field of communication disorders, have shed new light on the nature of neuroplasticity and reorganization of brain function as it pertains to recovery from nonfluent aphasia following Melodic Intonation Therapy (MIT). However, demographic limitations in these client populations necessitate synthesis across individual studies to form meaningful patterns for application to clinical practice. We conducted a systematic review of all studies involving pre-and post-treatment neurological and behavioral measures following MIT treatment for adults with nonfluent aphasia. Ten studies were identified for synthesis involving a variety of languages, treatment conditions, and neuroimaging and …

Interpretation Of Ambiguous Pronouns In Adults With Intellectual Disabilities, Kara Hawthorne, Susan J. Loveall

Department of Special Education and Communication Disorders: Faculty Publications

Background — Pronouns are referentially ambiguous (e.g. she could refer to any female), yet they are common in everyday conversations. Individuals with typical development (TD) employ several strategies to avoid pronoun interpretation errors, including the subject bias — an assumption that a pronoun typically refers to the subject (or, with the closely related order-of-mention bias, the first-mentioned character) of the previous sentence. However, it is unknown if adults with intellectual disability (ID) share this strategy or the extent to which the subject bias is associated with non-verbal abilities or receptive vocabulary.

Methods — We tested 22 adults with mixed-aetiology ID …

Behind The Scenes Of Noninvasive Brain– Computer Interfaces: A Review Of Electroencephalography Signals, How They Are Recorded, And Why They Matter, Kevin M. Pitt, Jonathan S. Brumberg, Jeremy D. Burnison, Jyutika Mehta, Juhi Kidwai

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: Brain–computer interface (BCI) techniques may provide computer access for individuals with severe physical impairments. However, the relatively hidden nature of BCI control obscures how BCI systems work behind the scenes, making it difficult to understand “how” electroencephalography (EEG) records the BCIrelated brain signals, “what” brain signals are recorded by EEG, and “why” these signals are targeted for BCI control. Furthermore, in the field of speech-languagehearing, signals targeted for BCI application have been of primary interest to clinicians and researchers in the area of augmentative and alternative communication (AAC). However, signals utilized for BCI control reflect sensory, cognitive, and motor …

Outcomes/Benefits: Within each consideration, a review of BCI research …

Guidelines For Feature Matching Assessment Of Brain–Computer Interfaces For Augmentative And Alternative Communication, Kevin M. Pitt, Jonathan S. Brumberg

Department of Special Education and Communication Disorders: Faculty Publications

Purpose--Brain–computer interfaces (BCIs) can provide access to augmentative and alternative communication (AAC) devices using neurological activity alone without voluntary movements. As with traditional AAC access methods, BCI performance may be influenced by the cognitive–sensory–motor and motor imagery profiles of those who use these devices. Therefore, we propose a person-centered, feature matching framework consistent with clinical AAC best practices to ensure selection of the most appropriate BCI technology to meet individuals' communication needs.

Method--The proposed feature matching procedure is based on the current state of the art in BCI technology and published reports on cognitive, sensory, motor, and motor …

Program Monitoring Practices For Teachers Of The Deaf And Hard Of Hearing In Early Intervention, Anne E. Thomas, Christine Marvin

Department of Special Education and Communication Disorders: Faculty Publications

Program monitoring is an important and necessary assessment practice within the field of early childhood deaf education. Effective program monitoring requires a focus on both the consistent implementation of intervention strategies (fidelity) and the assessment of children’s ongoing progress in response to interventions (progress monitoring). Teachers of the deaf and hard of hearing (TODs) who provide early intervention services need to conduct regular program monitoring to evaluate the merit of their efforts. However, progress monitoring is a practice often overlooked by practitioners within the field of early intervention. It is recommended that TODs monitor children’s progress “regularly,” but evidence of …

Three Reading-Intervention Teachers’ Identity Positioning And Practices To Motivate And Engage Emergent Bilinguals In An Urban Middle School, Jung-In Kim, Kara Mitchell Viesca

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This study investigated three urban middle-school teachers’ practices with respect to motivating and engaging emergent bilinguals in reading-intervention classrooms by exploring the teachers’ identity positioning. The three teachers’ sociocultural and sociopolitical positioning of their students (e.g. students as individuals, as monolithic learners, or as problems) was found to be related to their practices for motivating and engaging the students (e.g. hybrid, calibrated, or imposed practices). The teachers’ historical and current resources partially shaped how they positioned their students. The findings support that teachers should not only learn motivational practices but also reflect critically on positioning processes in the classroom.
