The goal of this dissertation was to find converging evidence from behavioral and neuroimaging analyses of the mechanisms of orthographic integration with general language processes. By examining orthography effects, covert influences of orthography on non-written tasks, in participants with aphasia, we attempt to elucidate the nature of…

This study evaluates spelling errors in the three subtypes of primary progressive aphasia (PPA): agrammatic (PPA-G), logopenic (PPA-L), and semantic (PPA-S). Forty-one PPA patients and 36 age-matched healthy controls were administered a test of spelling. The total number of errors and types of errors in spelling to dictation of regular words,…

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…

A report on a study of a large number of subjects afflicted with sensory aphasia. Topics covered are: the distributional pattern of grammatical categories; paraphasia; a statistical analysis of associated syndromes; possible relationship to the location of the lesion. Some examples of spontaneous language are included. (Text is in French.) (AMH)

A report on research on agraphia using subjects afflicted with sensory aphasia. It compares performance in Italian, a phonetic language, with performance in French. The disorders in the Italian language appear less varied than in French. (Text is in French.)

A study of graphic disorders observed afflicted with cortical lesions. The topics discussed are: elements of graphic activity, linguistic theories on the relationship between written and spoken language and the principal theses of aphasiologists on disorders in written language. A bibliography is attached. (Text is in French.) (AMH)

This article considers the acquisition and command of written language and how it is affected by brain damage. The aim is to show the close connections between psychology, linguistics and medical brain research. (Text is in German.) (TL)

Deals with the problem of transcoding, that is, when in switching from one sign system to another relations must be created between corresponding structures in the different systems. The mechanisms of transcoding are examined for spoken and written speech, numeral words and figures, and tone symbols and musical notes. (SCC)

A patient with chronic agrammatic Broca's aphasia exhibited deep dyslexia and was treated with functional reorganization of the phonetic route of reading, with the patient learning consciously to control formerly automatic behaviors. The patient's responses indicated that the phonetic route encompasses at least two dissociable functions:…

Separate experiments investigated parietal lobe malfunction; developmental v acquired dyslexia; whole-word, syllabic, and alphabetical reading ability; phonological recoding; and spelling. Reading processes and memory of normal and aphasic children were compared. (CP)
