Previous research has demonstrated mixed findings pertaining to the risk conferred by variation from Mainstream American English (MAE) for African American children in our education system. Based on the research on language, behavior, and reading, the present study sought to examine the relative and combined contributions of culturally appropriate...

While most graduate health professions programs in the United States have accepted the Interprofessional Education Collaborative’s core competencies for collaborative practice, there is no consistent way to integrate the competencies into courses of study already crowded with uniprofessional competencies. A potential negative effect of treating int...

The importance of interprofessional education and practice has been well documented for all health care disciplines. Our health care delivery system is challenged by the need to prepare health professions graduates with skills that get them ready to function as collaborative members of the health care team. Educators have long struggled to create i...

Buy Article Permissions and Reprints As the new Editors-in-Chief of Seminars in Speech and Language, we are honored to have the opportunity to develop issues of importance and relevance for our colleagues in speech-language pathology. As a team, we are committed to finding topics and leading-edge scholars from around the country and beyond, to offe...

The complex challenge of evaluating the impact of interprofessional education (IPE) on patient and community health outcomes is well documented. Recently, at the Radcliffe Institute for Advanced Study in the United States, leaders in health professions education met to help generate a direction for future IPE evaluation research. Participants follo...

This is an ebook published by the American Speech-Language-Hearing Association. The chapters provide an overview of IPE/IPP, descriptions of applications in higher education, health settings, and in K-12 settings.

Background: Negative affectivity and neurocognitive deficits including executive dysfunction have been shown to be detrimental to rehabilitation therapies. However, research on the relationship between neuropsychological deficits and improvement in speech-language therapy (SLT) for aphasia is sparse. Objective: To examine the relationships among...

The Affordable Care Act will shake up insurance reimbursement, and audiologists and speech-language pathologists will feel the effects.

This article summarizes a series of trips sponsored by People to People, a professional exchange program. The trips described in this report were led by the first author of this article and include trips to South Africa, Russia, Vietnam and Cambodia, and Israel. Each of these trips included delegations of 25 to 50 speech-language pathologists and a...

Quality-of-life indicators for dysphagia provide invaluable information to the treating clinician regarding the success or failure of swallowing therapy. The purpose of this study was to develop a clinically efficient, statistically robust patient-reported outcomes tool that measures the handicapping effect of dysphagia on emotional, functional, an...

In this study we investigated quality of life and functional communication activities in a sample of typical Taiwanese communicators and people who stutter (PWS) using an adapted version of the Quality of Communication Scale. In the first phase of this investigation we adapted the Quality of Communication Scale for the Taiwanese population. In the...

This article is presented in a question and answer format and shares the thoughts of the 2006 President of the American Speech-Language-Hearing Association (ASHA), Alex Johnson, and current Executive Director of ASHA, Arlene Pietranton, regarding several regulatory issues that the professions of audiology and/or speech-language pathology are likely...

Significant relations among language impairments, academic difficulties, and behavioral problems have been well established in previous research, primarily with impaired children or non-minority samples. However, how and why these three developmental domains tend to co-vary has received only limited attention. Preliminary research suggests that aca...

In 90% of normal subjects, the left hemisphere is dominant for language function. We investigated whether congenital lesions of the left perisylvian regions altered cortical language representation in right-handed individuals. Using functional magnetic resonance imaging, we studied language hemispheric dominance in five right-handed adult patients...

In 95% of right handed individuals the left hemisphere is dominant for speech and language function. The evidence for this is accumulated primarily from clinical populations. We investigated cortical topography of language function and lateralization in a sample of the right handed population using functional magnetic resonance imaging and two lexi...

Two mechanisms for recovery from aphasia, repair of damaged language networks and activation of compensatory areas, have been proposed. In this study, we investigated whether both mechanisms or one instead of the other take place in the brain of recovered aphasic patients. Using blood oxygenation level-dependent functional MRI (fMRI), we studied co...

Over the past 25 years, neuroimaging techniques have advanced rapidly. These techniques, including computed tomography, magnetic resonance imaging, positron emission tomography and single photon emission computed tomography, have improved our understanding of the relationships of language, language disorder, and brain language organization. In this...

To date, no instruments exist to quantify the psychosocial consequences of voice disorders. The aim of the present investigation was the development of a statistically robust Voice Handicap Index (VHI). An 85-item version of this instrument was administered to 65 consecutive patients seen in the Voice Clinic at Henry Ford Hospital. The data were su...

Currently, early phonatory changes in amyotrophic lateral sclerosis (ALS) are not well understood. The aim of this study was to compare acoustic parameters of voice in ALS subjects who demonstrated perceptually normal vocal quality on sustained phonation with a control group. We hypothesized that objective analysis of voice would reveal significant...

Voice disorders are commonly seen in general medical practice. In some cases voice disorders represent the presenting symptom for serious underlying disease. It is important for clinicians from internal medicine, pediatrics, and family practice to be able to identify those factors in the history or observed vocal symptoms which suggest need for ref...

This study recorded and analysed conversation samples from a group of six people with chronic aphasia during three different sampling conditions. The authors examined each group member's verbal output using components of SALT for Windows ® (Miller & Chapman, 1999) and a preliminary conversational-turn rating system. Results showed high variability...
