In three experiments we assessed the colour knowledge of patients with semantic dementia, a neuro-degenerative condition that gradually erodes conceptual knowledge. In Experiment 1, the patients' colour naming performance correlated strongly with their object naming for frequency-matched items, with no patient showing better-than-expected naming of colours relative to objects. In Experiment 2, ...

Fluent primary progressive aphasia (fPPA) is very often confused with semantic dementia (SD), due to the ambiguity of the latter term. We present a case of fPPA with neuropsychological and neuroimaing data, not fulfilling the diagnostic criteria for SD. The language disturbance profile is presented, resembling transcortical sensory aphasia. The results of both standardized and experimental test...

Although some studies have reported a category specific naming deficit in Alzheimer’s patients (invariably for living things), others have failed to replicate this finding (Laws et al., in press). Inconsistencies may partly stem from the fact that category effects are hidden in group analyses because individual Alzheimer’s patients show category deficits in opposing directions, namely, some liv...

Objectives: Semantic Feature Analysis was designed to improve lexical retrieval of aphasic patients via activation of semantic networks of the words. In this approach, the anomic patients are cured with semantic information to assist oral naming. The purpose of this study was to examine the effects of Semantic Feature Analysis treatment on anomia of two nonfluent aphasic patients. Methods: A...

Letter position dyslexia (LPD) is a peripheral dyslexia that causes errors of letter order within words. So far, only cases of acquired LPD have been reported. This study presents selective LPD in its developmental form, via the testing of II Hebrew-speaking individuals with developmental dyslexia. The study explores the types of errors and effects on reading in this dyslexia, using a variety o...

We examined the double-deficit hypothesis in Finnish. One-hundred-and five Finnish children with high familial risk for dyslexia and 90 children with low family risk were followed from the age of 3.5 years until grade 3. Children’s phonological awareness, rapid naming speed, text reading and spelling were assessed. A deficit in RAN predicted slow reading speed across time and spelling difficult...

Eleven of 13 children, who demonstrated a failure-to-thrive pattern in infancy attributable to chloride-deficient Neo-Mull-Soy formula, had distinctive cognitive impairments four to nine years later. These included: a language disorder primarily involving articulation, word finding and naming; visual-motor and fine motor difficulties; and attention deficit disorder, often featuring repetitive b...

An extensive study of the language abilities of one deep dyslexic patient, B.L., was undertaken. Tests of his ability to comprehend and produce words in the auditory, verbal, and graphic modalities revealed striking similarities in performance across modalities, such that the defining symptoms of deep dyslexic reading also held true for this patient’s writing, repetition, and naming. A new dual...
