”To Be Or Not To Be – It’S Good”: Actor And Student Experiences In A Drama Club For People With Aphasia, Jade K. Hannan

Senior Theses

Individuals with aphasia, a disorder caused by damage to the brain’s language network, confront a variety of social and emotional struggles. While leaving their cognition largely intact, aphasia tremendously impacts a person’s ability to communicate confidently, fracturing their social network and contributing to feelings of loneliness and frustration. To address this persistent need in the chronic aphasia population, the Play on Words drama club at the University of South Carolina provides a forum for people with aphasia (PWA) to engage in dramatic exercises focused on non-verbal communication of emotions, ideas, and stories, culminating the production of an original devised play. …

The Effect Of Visual Feedback On Vocal Compensation Abilities In Individuals With Post-Stroke Aphasia, Marissa Rylee Olson

Theses and Dissertations

Speech production is a complex and highly organized process comprised of various sensory and perceptual components. Post-stroke aphasia can impair speech production abilities by interrupting individuals’ ability to detect and correct speech errors and produce their targeted behavior. Contemporary models of speech production aim to understand the relationship between sensory systems and the human ability to produce perceptually accurate speech. This study seeks to understand the relationship between visual feedback and vocal compensation abilities in individuals with post-stroke aphasia to determine the effectiveness of incorporating visual feedback into therapeutic expressive language intervention. It was hypothesized that that the multi-sensory experimental …

Investigating The Impact Of Nonlinguistic Cognitive Reserve On Naming Pre- And Post-Treatment, Lillian Jarold

Theses and Dissertations

Background: The relationship between linguistic and nonlinguistic cognition in persons with aphasia is complex and often debated in the literature. Furthermore, the impact of nonlinguistic cognition on aphasia treatment outcomes is unclear. The present study sought 1) to examine the relationship between WAIS scores and performance on a test of naming and 2) to examine the relationship between WAIS scores and change scores on a test of naming between baseline and post-treatment in persons with chronic aphasia.

Method: This retrospective study utilized data from participants (N=102) who were recruited for a multi-center cross-over trial (POLAR: Predicting Outcomes of Language Rehabilitation). …

Transcranial Alternating Current Stimulation As An Adjuvant For Nonfluent Aphasia Therapy: A Proof-Of-Concept Study, Lynsey Mcgrath Keator

Theses and Dissertations

Identifying effective and efficient rehabilitation tools is crucial to improve language outcomes for persons living with chronic aphasia. Speech entrainment has proved to be particularly successful in improving speech output in nonfluent aphasia. It is hypothesized that, for patients with aberrant oscillatory synchronization between anterior and posterior language regions of the left hemisphere, speech entrainment may act as an external gaiting mechanism to bolster an impaired efference copy and improve synchrony between these regions. Theoretical and empirical evidence supports this idea that speech production relies on anterior-posterior connectivity in the left hemisphere.

Transcranial alternating current stimulation (tACS) delivers low, periodically-alternating …

Towards Understanding Therapy Response In Chronic Aphasia, Sigfus Kristinsson

Theses and Dissertations

It remains largely unclear what factors determine who responds to aphasia therapy and to what degree. The current study sought to ameliorate this issue by addressing three aims: 1) To identify baseline predictors that dissociate between therapy responders and nonresponders, 2) to identify predictors of degree of treated recovery in therapy responders, and 3) to examine the generalizability of predictors identified under Aims 1 and 2 in randomly selected subsamples of study participants.

Method: Stroke survivors (N = 102; 43 females; age = 60.5y +/- 11.0y) with chronic aphasia (>12m post-stroke) were recruited as part of a multisite trial. …

Neural Synchrony During Naturalistic Language Perception In Listeners With Aphasia, Lisa Johnson Norris

Theses and Dissertations

Neural synchrony across listeners during language processing has been found to be associated with successful comprehension in neurotypical adults. At initial presentation of auditory-visual stimuli, neural responses appear to oscillate in different rhythms across brain regions. As the stimulus progresses, the time course of neural activity synchronizes across listeners, particularly in primary auditory and visual processing regions. This phenomenon, which we refer to as ‘neural entrainment,’ has been observed in neurotypical individuals attending to the same stimulus. Neural synchrony occurs due to the inherent neural response elicited by a stimulus and has been shown to be consistent across participants in …

Behavioral And Neurophysiological Correlates Of Sensorimotor Impairment In Aphasia, Lorelei Phillip Johnson

Theses and Dissertations

Developing a clearer understanding of the basic impairments which underlie the behavioral characteristics of aphasia is essential for informing the development of targeted and effective treatment techniques. Impairments in sensorimotor integration have already been implicated in the repetition deficits common to individuals with aphasia, but much less is known about the extent to which these integrative deficits occur outside of conduction aphasia and how this manifests behaviorally in areas other than speech repetition. The goal of the present study was to examine these issues further by addressing the following aims: 1) To examine the behavioral and neurophysiological correlates of sensorimotor …

Effects Of Language Predictability And Speech Rate On Speech Entrainment Performance In Healthy Individuals, Honey Isabel Hubbard

Theses and Dissertations

Speech entrainment, a paradigm in which a participant shadows the speech of an audiovisual model in real time, has been show to benefit individuals with non-fluent aphasia. A study examining the effects of language predictability and speech rate was conducted to understand factors that influence speech entrainment performance.

A recent study by Fridriksson and colleagues (2012) demonstrated that training with speech entrainment significantly increased the number of words participants with non-fluent aphasia were able to produce. Perhaps even more remarkably, these effects showed generalization. As a result, speech entrainment could be used to rehabilitate speech impairment in stroke. However, there …

Narrative Discourse In Aphasia: Main Concept And Core Lexicon Analyses Of The Cinderella Story, Emily Patricia Dillow

Theses and Dissertations

Discourse is a highly individualized and complex speech act essential for effective communication in daily life. Individuals with language disorders demonstrate impaired narrative ability and a resultant decline in functional communication (Webster, Franklin, & Howard, 2007). Discourse analysis is often time-consuming and impractical for everyday clinical use. Most informative discourse measures require specialized training to perform and are time-consuming. A clinically practical measurement is lacking. Standardized core lexicon and main concept lists for discourse tasks could allow clinicians to efficiently assess discourse skills and predict activity and participation limitations. This study presents the development and application of a core lexicon …
