Purpose: The impact of stimulus-level psycholinguistic variables and personlevel semantic and phonological processing skills on treatment outcomes in individuals with aphasia requires further examination to inform clinical decision making in treatment prescription and stimuli selection. This study investigated the influence of stimulus-level…

Background: Evidence-based recommendations for a core outcome set (COS; minimum set of outcomes) for aphasia treatment research have been developed (the Research Outcome Measurement in Aphasia--ROMA, COS). Five recommended core outcome constructs: communication, language, quality of life, emotional well-being and patient-reported…

Kiran, Swathi; Meier, Erin L.; Johnson, Jeffrey P. – Journal of Speech, Language, and Hearing Research, 2019
Purpose: Despite a tremendous amount of research in this topic, the precise neural mechanisms underlying language recovery remain unclear. Much of the evidence suggests that activation of remaining left-hemisphere tissue, including perilesional areas, is linked to the best treatment outcomes, yet recruitment of the right hemisphere for various…

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…

An Examination of Strategy Implementation during Abstract Nonlinguistic Category Learning in Aphasia
Vallila-Rohter, Sofia; Kiran, Swathi – Journal of Speech, Language, and Hearing Research, 2015
Purpose: Our purpose was to study strategy use during nonlinguistic category learning in aphasia. Method: Twelve control participants without aphasia and 53 participants with aphasia (PWA) completed a computerized feedback-based category learning task consisting of training and testing phases. Accuracy rates of categorization in testing phases…

Kiran, Swathi; Sandberg, Chaleece; Gray, Teresa; Ascenso, Elsa; Kester, Ellen – American Journal of Speech-Language Pathology, 2013
Purpose: The goal of this study was to examine if there was a principled way to understand the nature of rehabilitation in bilingual aphasia such that patterns of acquisition and generalization are predictable and logical. Method: Seventeen Spanish-English bilingual individuals with aphasia participated in the experiment. For each participant,…

Sandberg, Chaleece; Sebastian, Rajani; Kiran, Swathi – Journal of Communication Disorders, 2012
Background: The typicality effect is present in neurologically intact populations for natural, ad-hoc, and well-defined categories. Although sparse, there is evidence of typicality effects in persons with chronic stroke aphasia for natural and ad-hoc categories. However, it is unknown exactly what influences the typicality effect in this…

Vallila-Rohter, Sofia; Kiran, Swathi – American Journal of Speech-Language Pathology, 2013
Purpose: The purpose of the current study was to explore nonlinguistic learning ability in individuals with aphasia, examining the impact of stimulus typicality and feedback on success with learning. Method: Eighteen individuals with aphasia and 8 nonaphasic controls participated in this study. All participants completed 4 computerized,…

Levy, Joshua; Hoover, Elizabeth; Waters, Gloria; Kiran, Swathi; Caplan, David; Berardino, Alex; Sandberg, Chaleece – American Journal of Speech-Language Pathology, 2012
Purpose: Prior studies of discourse comprehension have concluded that the deficits of persons with aphasia (PWA) in syntactically based comprehension of sentences in isolation are not predictive of deficits in comprehension of sentences in discourse (Brookshire & Nicholas, 1984; Caplan & Evans, 1990). However, these studies used semantically…

Kiran, Swathi; Sandberg, Chaleece; Sebastian, Rajani – Journal of Speech, Language, and Hearing Research, 2011
Purpose: Kiran and colleagues (Kiran, 2007, 2008; Kiran & Johnson, 2008; Kiran & Thompson, 2003) previously suggested that training atypical examples within a semantic category is a more efficient treatment approach to facilitating generalization within the category than training typical examples. In the present study, the authors extended…

Kiran, Swathi; Grasemann, Uli; Sandberg, Chaleece; Miikkulainen, Risto – Bilingualism: Language and Cognition, 2013
Current research on bilingual aphasia highlights the paucity in recommendations for optimal rehabilitation for bilingual aphasic patients (Edmonds & Kiran, 2006; Roberts & Kiran, 2007). In this paper, we have developed a computational model to simulate an English-Spanish bilingual language system in which language representations can vary by age…

Kiran, Swathi; Iakupova, Regina – Clinical Linguistics & Phonetics, 2011
The goal of this study was to address the relationship between language proficiency, language impairment and rehabilitation in bilingual Russian-English individuals with aphasia. As a first step, we examined two Russian-English patients' pre-stroke language proficiency using a detailed and comprehensive language use and history questionnaire and…

Kiran, Swathi; Johnson, Lauren – American Journal of Speech-Language Pathology, 2008
Purpose: Our previous work on manipulating typicality of category exemplars during treatment of naming deficits has shown that training atypical examples generalizes to untrained typical examples but not vice versa. In contrast to natural categories that consist of fuzzy boundaries, well-defined categories (e.g., "shapes") have rigid…

Kiran, Swathi; Caplan, David; Sandberg, Chaleece; Levy, Joshua; Berardino, Alex; Ascenso, Elsa; Villard, Sarah; Tripodis, Yorghos – American Journal of Speech-Language Pathology, 2012
Purpose: Two new treatments, 1 based on sentence to picture matching (SPM) and the other on object manipulation (OM), that train participants on the thematic roles of sentences using pictures or by manipulating objects were piloted. Method: Using a single-subject multiple-baseline design, sentence comprehension was trained on the affected sentence…

Kiran, Swathi – Journal of Speech, Language, and Hearing Research, 2008
Purpose: The typicality treatment approach on improving naming was investigated within 2 inanimate categories ("furniture" and "clothing") using a single-subject experimental design across participants and behaviors in 5 patients with aphasia. Method: Participants received a semantic feature treatment to improve naming of either typical or…
