Marangolo, Paola; Bonifazi, Silvia; Tomaiuolo, Francesco; Craighero, Laila; Coccia, Michela; Altoe, Gianmarco; Provinciali, Leandro; Cantagallo, Anna – Neuropsychologia, 2010
The pervasiveness of word-finding difficulties in aphasia has motivated several theories regarding management of the deficit and its effectiveness. Recently, the hypothesis was advanced that instead of simply accompanying speech gestures participate in language production by increasing the semantic activation of words grounded in sensory-motor…

Rochon, Elizabeth; Leonard, Carol; Burianova, Hana; Laird, Laura; Soros, Peter; Graham, Simon; Grady, Cheryl – Brain and Language, 2010
Functional magnetic resonance imaging (fMRI) was used to investigate the neural processing characteristics associated with word retrieval abilities after a phonologically-based treatment for anomia in two stroke patients with aphasia. Neural activity associated with a phonological and a semantic task was compared before and after treatment with…

Miozzo, Michele; Fischer-Baum, Simon; Postman, Jeffrey – Neuropsychologia, 2010
We report the case of an English-speaking aphasic patient (JP) with left posterior-frontal damage affecting the inferior frontal and precentral gyri. In speaking, JP was impaired with the regular inflections of nouns and pseudonouns, making errors like "pears" instead of "pear" or "door" for "doors", while the spoken production of noun stems and…

Zanini, Sergio; Angeli, Valentina; Tavano, Alessandro – Clinical Linguistics & Phonetics, 2011
We report on the case of an elderly bilingual woman presenting with a diagnosis of primary progressive aphasia. The participant's native language was Friulian (L1), a predominantly oral Romance language, and her second language was Italian (L2), formally learned at primary school in oral and written forms. We investigated her linguistic abilities…

Richardson, Fiona M.; Thomas, Michael S. C.; Price, Cathy J. – Journal of Cognitive Neuroscience, 2010
Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. In our study, we used fMRI to compare the processing of semantically reversible 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…

Alladi, Suvarna; Mridula, Rukmini; Mekala, Shailaja; Rupela, Vani; Kaul, Subhash – Indian Journal of Applied Linguistics, 2010
This study presents two cases with fluent aphasia in Telugu with semantic dementia and post-stroke fluent aphasia. Comparable scores were obtained on the conventional neuropsychological and language tests that were administered on the two cases. Both cases demonstrated fluent, grammatical and well-articulated speech with little content, impaired…

Ciaghi, Maddalena; Pancheri, Elisa; Miceli, Gabriele – Brain and Language, 2010
We studied the reading performance of 340 consecutive, Italian-speaking aphasics in order to evaluate the clinical features of deep dyslexia, the functional impairments underlying semantic paralexias, and their neuranatomical correlates. Semantic paralexias were observed in 9/340 subjects (2.4%). Our data and a review of the literature show that…

Jefferies, Elizabeth; Rogers, Timothy T.; Hopper, Samantha; Lambon Ralph, Matthew A. – Neuropsychologia, 2010
Patients with semantic dementia show a specific pattern of impairment on both verbal and non-verbal "pre-semantic" tasks, e.g., reading aloud, past tense generation, spelling to dictation, lexical decision, object decision, colour decision and delayed picture copying. All seven tasks are characterised by poorer performance for items that are…

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…

George, Annamma; Mathuranath, P. S. – Indian Journal of Applied Linguistics, 2010
Primary Progressive Aphasia (PPA) is a degenerative condition characterized by deterioration in language for at least two years without deterioration in other cognitive domains. This report highlights the language profile in a 79-year-old male with progressive nonfluent aphasia (PNFA) who was assessed using the Western Aphasia Battery and the…

Kambanaros, Maria – Journal of Communication Disorders, 2008
In the past verb retrieval problems were associated primarily with agrammatism and noun retrieval difficulties with fluent aphasia. With regards to fluent aphasia, so far in the literature, three distinct patterns of verb/noun dissociations have been described for individuals with fluent anomic aphasia in languages with different underlying forms;…

Radford, Julie – Clinical Linguistics & Phonetics, 2009
Word finding difficulties in children are typically characterized by search behaviours such as silence, circumlocution, repetition, and empty words. Yet, how children's word searches are constructed (including gesture, gaze, and prosody) and the actions accomplished during interaction have not yet been researched. In this study, 8-year-old Ciara…

Kiran, Swathi – American Journal of Speech-Language Pathology, 2007
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…

Rohrer, Jonathan D.; Crutch, Sebastian J.; Warrington, Elizabeth K.; Warren, Jason D. – Neuropsychologia, 2010
The neuropsychological features of the primary progressive aphasia (PPA) syndromes continue to be defined. Here we describe a detailed neuropsychological case study of a patient with a mutation in the progranulin ("GRN") gene who presented with progressive word-finding difficulty. Key neuropsychological features in this case included gravely…
