van Nispen, Karin; van de Sandt-Koenderman, Mieke; Mol, Lisette; Krahmer, Emiel – Journal of Speech, Language, and Hearing Research, 2016
Purpose: The present article aimed to inform clinical practice on whether people with aphasia (PWA) deploy pantomime techniques similarly to participants without brain damage (PWBD) and if not, what factors influence these differences. Method: We compared 38 PWA to 20 PWBD in their use of 6 representation techniques ("handling,"…

Ramage, Amy E.; Aytur, Semra; Ballard, Kirrie J. – Journal of Speech, Language, and Hearing Research, 2020
Purpose: Brain imaging has provided puzzle pieces in the understanding of language. In neurologically healthy populations, the structure of certain brain regions is associated with particular language functions (e.g., semantics, phonology). In studies on focal brain damage, certain brain regions or connections are considered sufficient or…

Castro, Nichol; Stella, Massimo; Siew, Cynthia S. Q. – Cognitive Science, 2020
Investigating instances where lexical selection fails can lead to deeper insights into the cognitive machinery and architecture supporting successful word retrieval and speech production. In this paper, we used a multiplex lexical network approach that combines semantic and phonological similarities among words to model the structure of the mental…

The Roles of Retrieval Practice versus Errorless Learning in Strengthening Lexical Access in Aphasia
Schuchard, Julia; Middleton, Erica L. – Journal of Speech, Language, and Hearing Research, 2018
Purpose: The purpose of this study was to determine how 2 methods known to improve naming impairment in aphasia (i.e., retrieval practice and errorless learning) affect lexical access. We hypothesized that instances of naming during retrieval practice use and strengthen item-specific connections in each of 2 stages of lexical access: Stage 1,…

Bose, Arpita; Wood, Rosalind; Kiran, Swathi – International Journal of Language & Communication Disorders, 2017
Background: Verbal fluency tasks are included in a broad range of aphasia assessments. It is well documented that people with aphasia (PWA) produce fewer items in these tasks. Successful performance on verbal fluency relies on the integrity of both linguistic and executive control abilities. It remains unclear if limited output in aphasia is…

Evans, William S.; Cavanaugh, Robert; Quique, Yina; Boss, Emily; Starns, Jeffrey J.; Hula, William D. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: The purpose of this study was to develop and pilot a novel treatment framework called "BEARS" (Balancing Effort, Accuracy, and Response Speed). People with aphasia (PWA) have been shown to maladaptively balance speed and accuracy during language tasks. BEARS is designed to train PWA to balance speed-accuracy trade-offs and…

Kladouchou, Vasiliki; Papathanasiou, Ilias; Efstratiadou, Eva A.; Christaki, Vasiliki; Hilari, Katerina – International Journal of Language & Communication Disorders, 2017
Background & Aims: This study ran within the framework of the Thales Aphasia Project that investigated the efficacy of elaborated semantic feature analysis (ESFA). We evaluated the treatment integrity (TI) of ESFA, i.e., the degree to which therapists implemented treatment as intended by the treatment protocol, in two different formats:…

Rebstock, Alicia M.; Wallace, Sarah E. – Communication Disorders Quarterly, 2020
Primary progressive aphasia (PPA) is a neurodegenerative condition characterized by language and cognitive decline. Word-retrieval deficits are the most common PPA symptom and contribute to impaired spoken expression. Intense semantic interventions show promise for improving word retrieval in people with PPA. In addition, people with PPA may learn…

Kurland, Jacquie; Liu, Anna; Stokes, Polly – Journal of Speech, Language, and Hearing Research, 2018
Purpose: The aim of this study was to determine if a tablet-based home practice program with weekly telepractice support could enable long-term maintenance of recent treatment gains and foster new language gains in poststroke aphasia. Method: In a pre-post group study of home practice outcomes, 21 individuals with chronic aphasia were examined…

Faroqi-Shah, Yasmeen; Milman, Lisa – International Journal of Language & Communication Disorders, 2018
Background: The ability to generate words that follow certain constraints, or verbal fluency, is a sensitive indicator of neurocognitive impairment, and is impacted by a variety of variables. Aims: To investigate the effect of post-stroke aphasia, elicitation category and linguistic variables on verbal fluency performance. Methods &…

Mason-Baughman, Mary Beth; Wallace, Sarah E. – Communication Disorders Quarterly, 2014
Previous studies suggest that people with aphasia have incomplete lexical-semantic representations with decreased low-importance distinctive (LID) feature knowledge. In addition, decreased LID feature knowledge correlates with ability to discriminate among semantically related words. The current study seeks to replicate and extend previous…

Dignam, Jade; Copland, David; O'Brien, Kate; Burfein, Penni; Khan, Asaduzzaman; Rodriguez, Amy D. – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The relationship between cognitive abilities and aphasia rehabilitation outcomes is complex and remains poorly understood. This study investigated the influence of language and cognitive abilities on anomia therapy outcomes in adults with aphasia. Method: Thirty-four adults with chronic aphasia participated in Aphasia Language Impairment…

Kaye, Rosalind C.; Cherney, Leora R. – Topics in Language Disorders, 2016
Purpose: Script training for aphasia involves repeated practice of relevant phrases and sentences that, when mastered, can potentially be used in other communicative situations. Although an increasingly popular approach, script development can be time-consuming. We provide a detailed summary of the evidence supporting this approach. We then…

Wambaugh, Julie L.; Mauszycki, Shannon; Cameron, Rosalea; Wright, Sandra; Nessler, Christina – American Journal of Speech-Language Pathology, 2013
Purpose: This investigation was designed to examine the generalization effects of semantic treatment for word retrieval deficits in people with aphasia. Semantic feature analysis (SFA; Boyle & Coelho, 1995), typicality treatment (Kiran & Thompson, 2003), and mediating strategy training were combined to maximize potential generalization effects.…

Haley, Katarina L.; Jacks, Adam; Jarrett, Jordan; Ray, Taylor; Cunningham, Kevin T.; Gorno-Tempini, Maria Luisa; Henry, Maya L. – Journal of Speech, Language, and Hearing Research, 2021
Purpose: Of the three currently recognized variants of primary progressive aphasia, behavioral differentiation between the nonfluent/agrammatic (nfvPPA) and logopenic (lvPPA) variants is particularly difficult. The challenge includes uncertainty regarding diagnosis of apraxia of speech, which is subsumed within criteria for variant classification.…
