Purpose: The ultimate goal of anomia treatment should be to achieve gains in exemplars trained in the therapy session, as well as generalization to untrained exemplars and contexts. The purpose of this study was to test the efficacy of phonomotor treatment, a treatment focusing on enhancement of phonological sequence knowledge, against semantic…

Background: Cognitive-linguistic treatments and interventions targeting communication have been developed within the context of primary progressive aphasia (PPA), however knowledge about the scope of generalization and maintenance of therapy gains considering PPA subtypes remains scarce and awaits systematic investigation. Aims: To analyse the…

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…

Previous research on participants with aphasia has mainly been based on standard functional neuroimaging analysis. Recent studies have shown that functional connectivity analysis can detect compensatory activity, not revealed by standard analysis. Little is known, however, about the default-mode network in aphasia. In the current study, we studied…

Verb retrieval difficulties are common in aphasia; however, few successful treatments have been documented (e.g. Conroy, P., Sage, K., & Lambon Ralph, M. A. (2006). Towards theory-driven therapies for aphasic verb impairments: A review of current theory and practice. "Aphasiology", 20, 1159-1185). This study investigated the efficacy of a novel…

As bilingualism becomes less exceptional in the world, and with the growing incidence of stroke and aphasia, a better understanding of how bilingualism affects aphasia recovery is increasingly important. The present study examined the effect of intensive semantic naming therapy in three phases (Spanish, English and mixed) on within- and…

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…

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…

Purpose: This article discusses a novel approach for treatment of lexical retrieval deficits in aphasia in which treatment begins with complex, rather than simple, lexical stimuli. This treatment considers the semantic complexity of items within semantic categories, with a focus on their featural detail. Method and Results: Previous work on…

Purpose: Semantic feature analysis (SFA) was used to determine whether training contextually related words would improve the discourse of individuals with nonfluent aphasia in preselected contexts. Method: A modified multiple-probes-across-behaviors design was used to train target words using SFA in 3 adults with nonfluent aphasia. Pretreatment,…
