Abstract
Purpose: In this study, we investigated the phenomenon of cognate status-based picture-naming abilities before and after anomia treatment in a multilingual person with poststroke aphasia whose languages vary in relation to language typology, age of acquisition, proficiency, and exposure/use in the years leading up to the stroke. We examined baseline abilities as well as the efficacy of within- and cross-language generalization.
Method: In a multiple-baseline study, we measured cognate versus noncognate picture-based naming in one multilingual person with mixed transcortical aphasia in three of his languages: Swahili, English, and Hebrew. We provided 18 hrs of word retrieval treatment in English and then retested his cognate versus noncognate retrieval in all three languages.
Results: At baseline, no cognate advantage was observed in English (high proficiency, early acquisition, high daily use). A cognate advantage was observed for Hebrew (late acquisition, moderate proficiency, oft-used) and potentially for Swahili (high proficiency, early acquisition, rarely used). After treatment in English, our results indicated greater interference effects for cognates relative to noncognates in Hebrew and Swahili, but not English.
Conclusions: Retrieval ability may be more influenced by prestroke usage than by age of acquisition or proficiency, with a facilitative cognate advantage for less proficient and/or less used languages. Furthermore, treating a stronger language may result in interference of cognate retrieval more than noncognate retrieval in weaker languages. More studies are needed in this field to better understand the contribution of each factor and how we can manipulate them to our advantage in the aphasia clinic.
期刊介绍：
Mission: AJSLP publishes peer-reviewed research and other scholarly articles on all aspects of clinical practice in speech-language pathology. The journal is an international outlet for clinical research pertaining to screening, detection, diagnosis, management, and outcomes of communication and swallowing disorders across the lifespan as well as the etiologies and characteristics of these disorders. Because of its clinical orientation, the journal disseminates research findings applicable to diverse aspects of clinical practice in speech-language pathology. AJSLP seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work.
Scope: The broad field of speech-language pathology, including aphasia; apraxia of speech and childhood apraxia of speech; aural rehabilitation; augmentative and alternative communication; cognitive impairment; craniofacial disorders; dysarthria; fluency disorders; language disorders in children; speech sound disorders; swallowing, dysphagia, and feeding disorders; and voice disorders.
