Asymmetric Event-Related Potential Priming Effects Between English Letters And American Sign Language Fingerspelling Fonts, Zed Sevcikova Sehyr, Katherine J. Midgley, Karen Emmory, Phillip J. Holcomb

Communication Sciences and Disorders Faculty Articles and Research

Letter recognition plays an important role in reading and follows different phases of processing, from early visual feature detection to the access of abstract letter representations. Deaf ASL–English bilinguals experience orthography in two forms: English letters and fingerspelling. However, the neurobiological nature of fingerspelling representations, and the relationship between the two orthographies, remains unexplored. We examined the temporal dynamics of single English letter and ASL fingerspelling font processing in an unmasked priming paradigm with centrally presented targets for 200 ms preceded by 100 ms primes. Event-related brain potentials were recorded while participants performed a probe detection task. Experiment 1 examined …

Varied Performance Of Picture Description Task As A Screening Tool Across Mci Subtypes, Joan A. Mefford, Zilong Zhao, Leah Heilier, Man Xu, Guifeng Zhou, Rachel Mace, Kelly L. Sloane, Shannon M. Sheppard, Shenly Glenn

A picture description task is a component of Miro Health’s platform for self-administration of neurobehavioral assessments. Picture description has been used as a screening tool for identification of individuals with Alzheimer’s disease and mild cognitive impairment (MCI), but currently requires in-person administration and scoring by someone with access to and familiarity with a scoring rubric. The Miro Health implementation allows broader use of this assessment through self-administration and automated processing, analysis, and scoring to deliver clinically useful quantifications of the users’ speech production, vocal characteristics, and language. Picture description responses were collected from 62 healthy controls (HC), and 33 participants …

Incog 2.0 Guidelines For Cognitive Rehabilitation Following Traumatic Brain Injury, Part Iii: Executive Functions, Eliyas Jeffay, Jennie Ponsford, Amber Harnett, Shannon Janzen, Eleni Patsakos, Jacinta Douglas, Mary Kennedy, Ailene Kua, Robert Teasell, Penny Welch-West, Mark Theodore Bayley, Robin Green

Communication Sciences and Disorders Faculty Articles and Research

Introduction:

Moderate-to-severe traumatic brain injury (MS-TBI) causes debilitating and enduring impairments of executive functioning and self-awareness, which clinicians often find challenging to address. Here, we provide an update to the INCOG 2014 guidelines for the clinical management of these impairments.

Methods:

An expert panel of clinicians/researchers (known as INCOG) reviewed evidence published from 2014 and developed updated recommendations for the management of executive functioning and self-awareness post-MS-TBI, as well as a decision-making algorithm, and an audit tool for review of clinical practice.

Results:

A total of 8 recommendations are provided regarding executive functioning and self-awareness. Since INCOG 2014, 4 …

Incog 2.0 Guidelines For Cognitive Rehabilitation Following Traumatic Brain Injury: What’S Changed From 2014 To Now?, Mark Theodore Bayley, Shannon Janzen, Amber Harnett, Peter Bragge, Leanne Togher, Ailene Kua, Eleni Patsakos, Lyn S.

IT IS CRITICAL TO KEEP clinical practice guidelines (CPGs) up to date through integration of the latest evidence. Therefore, it is with great excitement that the INCOG team presents the INCOG 2.0 Guidelines for Cognitive Rehabilitation Following Traumatic Brain Injury (TBI). In this brief introduction, we provide an overview of changes in the evidence from 2014; share insights into the current state and challenges implementing cognitive rehabilitation; and provide an overview of INCOG 2022.

Introduction:

Moderate to severe traumatic brain injury causes significant cognitive impairments, including impairments in social cognition, the ability to recognize others' emotions, and infer others' thoughts. These cognitive impairments can have profound negative effects on communication functions, resulting in a cognitive-communication disorder. Cognitive-communication disorders can significantly limit a person's ability to socialize, work, and study, and thus are critical targets for intervention. This article presents the updated INCOG 2.0 recommendations for management of cognitive-communication disorders. As social cognition is central to cognitive-communication disorders, this update includes interventions for social cognition.

Methods:

An expert panel of clinicians/researchers reviewed evidence published since …

The Future Of Incog (Is Now), Peter Bragge, Mark Theodore Bayley, Diana Velikonja, Leanne Togher, Jennie Ponsford, Shannon Janzen, Amber Harnett, Ailene Kua, Eleni Patsakos, Amanda Mcintyre, Robert Teasell, Mary Kennedy, Shawn Marshall

IT HAS BEEN 8 years since the first iteration of the INCOG clinical practice guidelines (CPGs) were published. Much has happened since 2014, and a considerable body of evidence has been published in the various domains of cognitive rehabilitation research represented in this special issue. Over this time, significant developments in the science of identifying, appraising, and distilling research evidence into practically applicable CPGs have emerged, as well as implementation efforts to ensure meaningful change in care delivery.

Introduction:

Memory impairments affecting encoding, acquisition, and retrieval of information after moderate-to-severe traumatic brain injury (TBI) have debilitating and enduring functional consequences. The interventional research reviewed primarily focused on mild to severe memory impairments in episodic and prospective memory. As memory is a common focus of cognitive rehabilitation, clinicians should understand and use the latest evidence. Therefore, the INCOG (“International Cognitive”) 2014 clinical practice guidelines were updated.

Methods:

An expert panel of clinicians/researchers reviewed evidence published since 2014 and developed updated recommendations for intervention for memory impairments post-TBI, a decision-making algorithm, and an audit tool for review of clinical practice. …

Explicit Training To Improve Affective Prosody Recognition In Adults With Acute Right Hemisphere Stroke, Alexandra Zezinka Durfee, Shannon M. Sheppard, Erin L. Meier, Lisa Bunker, Erjia Cui, Ciprian Crainiceanu, Argye E. Hillis

Communication Sciences and Disorders Faculty Articles and Research

Difficulty recognizing affective prosody (receptive aprosodia) can occur following right hemisphere damage (RHD). Not all individuals spontaneously recover their ability to recognize affective prosody, warranting behavioral intervention. However, there is a dearth of evidence-based receptive aprosodia treatment research in this clinical population. The purpose of the current study was to investigate an explicit training protocol targeting affective prosody recognition in adults with RHD and receptive aprosodia. Eighteen adults with receptive aprosodia due to acute RHD completed affective prosody recognition before and after a short training session that targeted proposed underlying perceptual and conceptual processes. Behavioral impairment and lesion characteristics were …

Diagnosing And Managing Post-Stroke Aphasia, Shannon M. Sheppard, Rajani Sebastian

Communication Sciences and Disorders Faculty Articles and Research

Introduction: Aphasia is a debilitating language disorder and even mild forms of aphasia can negatively affect functional outcomes, mood, quality of life, social participation, and the ability to return to work. Language deficits after post-stroke aphasia are heterogeneous.

Areas covered: The first part of this manuscript reviews the traditional syndrome-based classification approach as well as recent advances in aphasia classification that incorporate automatic speech recognition for aphasia classification. The second part of this manuscript reviews the behavioral approaches to aphasia treatment and recent advances such as noninvasive brain stimulation techniques and pharmacotherapy options to augment the effectiveness of …
