PURPOSE The neural mechanisms that support aphasia recovery are not yet fully understood. Our goal was to evaluate longitudinal changes in naming recovery in participants with posterior cerebral artery (PCA) stroke using a case-by-case analysis. METHODS Using task based and resting state functional magnetic resonance imaging (fMRI) and detailed language testing, we longitudinally studied the ...

We investigated the critical contribution of right ventral occipitotemporal cortex to knowledge of visual and functional-associative attributes of biological and non-biological entities and how this relates to category-specificity during confrontation naming. In a consecutive series of 7 patients with lesions confined to right ventral occipitotemporal cortex, we conducted an extensive assessmen...

Objective. Object naming for specific semantic categories was assessed in a sample of 24 patients with left temporal lobe epilepsy. Testing occurred during preoperative clinical diagnostics and 6 months after surgery. Background. Category-specific deficits constitute a naming disorder for living or nonliving objects or subsets of these categories (e.g. animals, fruits, tools) with relatively sp...

Abstract This study investigated the triple-deficit hypothesis in Arabic, a Semitic transparent orthography, among 258 native Arabic children from Grade 3, divided into typical readers group ( n = 204) and dyslexia 54). Children were tested on word- pseudoword-reading accuracy, word-reading fluency, phonological awareness (PA), naming speed (NS), orthographic processing (OP), nonverbal reasonin...

PURPOSE The semantic abilities of children with pragmatic language impairment (PLI) are subject to debate. The authors investigated picture naming and definition skills in 5-year-olds with PLI in comparison to typically developing children. METHOD 84 children with PLI and 80 age-matched typically developing children completed receptive vocabulary, picture naming, and definition tasks. RESUL...

This study was designed to explore the nature of the anomia that is a defining feature of semantic dementia. Using a pool of 225 sets of picture naming data from 78 patients, we assessed the effects on naming accuracy of several characteristics of the target objects or their names: familiarity, frequency, age of acquisition and semantic domain (living/non-living). We also analysed the distribut...

We investigated the influence of phonological neighbourhood density (PND) on the performance of aphasic speakers whose naming impairments differentially implicate phonological or semantic stages of lexical access. A word comes from a dense phonological neighbourhood if many words sound like it. Limited evidence suggests that higher density facilitates naming in aphasic speakers, as it does in h...

We report the naming performance of an early and highly proficient Spanish-Catalan bilingual (JPG) suffering from Primary Progressive Aphasia (PPA). JPG's performance revealed a grammatical category-specific deficit, with worse performance in naming verbs than nouns. This dissociation was present in oral and written naming and in his two languages, and it seems to stem from damage to, at least,...

The contributions of executive function, naming, visuoperception, and delayed recall to everyday memory abilities and everyday living activities were examined in a sample (n = 24) of mildly impaired Alzheimer's disease (AD) patients. Everyday memory was rated independently by the patient and by a caregiver, and everyday functioning was rated by a caregiver. For patient-rated everyday memory, ve...
