Effects Of Positive And Negative Emotion On Picture Naming For People With Mild To Moderate Aphasia: A Preliminary Investigation, Tyson G. Harmon, Courtney Nielsen, Corinne Loveridge, Camille Williams

Faculty Publications

Purpose: To investigate how emotional arousal and valence affect confrontational naming accuracy and response time in people with mild to moderate aphasia compared with adults without aphasia. We hypothesized that negative and positive emotions would facilitate naming for people with aphasia but lead to slower responses for adults with no aphasia.

Method: Eight participants with mild to moderate aphasia, 15 older adults, and 17 young adults completed a confrontational naming task across three conditions (positive, negative, neutral) in an ABA case series design. Immediately following each naming condition, participants self-reported their perceived arousal and pleasure. Accuracy and response time were …

Current Approaches To The Treatment Of Post-Stroke Aphasia, Julius Fridriksson Ph.D., Argye Elizabeth Hillis

Faculty Publications

Aphasia, impairment of language after stroke or other neurological insult, is a common and often devastating condition that affects nearly every social activity and interaction. Behavioral speech and language therapy is the mainstay of treatment, although other interventions have been introduced to augment the effects of the behavioral therapy. In this narrative review, we discuss advances in aphasia therapy in the last 5 years and focus primarily on properly powered, randomized, controlled trials of both behavioral therapies and interventions to augment therapy for post-stroke aphasia. These trials include evaluation of behavioral therapies and computer-delivered language therapies. We also discuss outcome …

Dual Task Effects On Story Retell For Participants With Moderate, Mild, Or No Aphasia: Quantitative And Qualitative Findings, Tyson G. Harmon, Adam Jacks, Katarina L. Haley, Antoine Bailliard

Faculty Publications

Purpose: To determine dual task effects on content accuracy, delivery speed, and perceived effort during narrative discourse in people with moderate, mild, or no aphasia and to explore subjective reactions to retelling a story with a concurrent task.

Method: Two studies (one quantitative and one qualitative) were conducted. In study 1, participants with mild or moderate aphasia and neurotypical controls retold short stories in isolation and while simultaneously distinguishing between high and low tones. Story retell accuracy (speech productivity and efficiency), speed (speech rate, repetitions, and pauses), and perceived effort were measured and compared. In study 2, participants completed semi-structured …

Speech Fluency In Acquired Apraxia Of Speech During Narrative Discourse: Group Comparisons And Dual Task Effects, Tyson G. Harmon, Adam Jacks, Katarina L. Haley

Faculty Publications

Purpose: Slowed speech and interruptions to the flow of connected speech are common in aphasia. These features are also observed during dual task performance for neurotypical adults. The purposes of this study were to determine (a) whether indices of fluency related to cognitive-linguistic versus motor processing would differ between speakers with aphasia plus AOS and speakers with aphasia only and (b) whether cognitive load reduces fluency in speakers with aphasia with and without AOS.

Method: Fourteen speakers with aphasia (seven with AOS) and seven neurotypical controls retold short stories alone (single task) and while simultaneously distinguishing between a high and …

Neural Plasticity And Treatment-Induced Recovery Of Sentence Processing In Agrammatism, Cynthia K. Thompson, Dirk B. Den Ouden, Borna Bonakdarpour, Kyla Garibaldi, Todd B. Parrish

Faculty Publications

This study examined patterns of neural activation associated with treatment-induced improvement of complex sentence production (and comprehension) in six individuals with stroke-induced agrammatic aphasia, taking into account possible alterations in blood flow often associated with stroke, including delayed time-to-peak of the hemodynamic response function (HRF) and hypoperfused tissue. Aphasic participants performed an auditory verification fMRI task, processing object cleft, subject cleft, and simple active sentences, prior to and following a course of Treatment of Underlying Forms (TUR; Thompson et al., 2003), a linguistically based approach for treating aphasic sentence deficits, which targeted objective relative clause constructions. The patients also were …
