This article provides a rationale for changing the base upon which healthcare services for individuals with stroke and aphasia can be provided. It summarizes the interaction between the Aphasia Institute and the West Greater Toronto Stroke Network who worked together to effect meaningful change. A set of guidelines is provided. (Contains…

Despite intensive work on language-brain relations, and a fairly impressive accumulation of knowledge over the last several decades, there has been little progress in developing large-scale models of the functional anatomy of language that integrate neuropsychological, neuroimaging, and psycholinguistic data. Drawing on relatively recent…

The Psychotic Behavior Rating Scale uses a factor analysis approach to aid in differential diagnosis of autism, schizophrenia, mental retardation, aphasia, and other severe handicaps. The scale is compared with five existing qualitatively developed instruments, noting similarities and dissimilarities among the various scales. (Author/JDD)

Discusses recent studies of aphasia from the perspective of theories of normal language structure and processing. Patterns of language breakdown are considered to reflect the componential structure of the language system. Brain damage is seen to fractionate language along lines suggested by existing psycholinguistic models. (Author)

Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

Two studies are reported in which the following theory is tested: the agrammatic sentence form that is observed in the spontaneous speech of Broca's aphasics is attributable to the selection of elliptical syntactic structures in which the slots for many of the closed-class words that appear in complete sentences are lacking. (54 references)…

Notes that in linguistic theory, phenomena previously handled by a separate grammatical component have been moved into the lexicon and that in some theories, the contrast between grammar and the lexicon has vanished. Concludes that the case for a modular distinction between grammar and the lexicon has been overstated and that the evidence to date…

This article presents an approach to a variety of syndromes and patterns of language disorders in bilingual speakers and polyglots. This framework demands that in neuropsychological analysis, all the variables and dynamics of bilingual development have to be taken into consideration, along with details of the neurological syndrome. (Contains…

Reading and writing deficits in two multilingual speakers of Kannada, Hindi and English are described. Disorders of the two patients (Mr G and Ms S) had different etiologies. Mr G had severe alexia with agraphia in English as well as in Kannada and Hindi. Ms S exhibited dissociation across the languages, showing symptoms of surface dyslexia in…

Aphasia implies the loss or impairment of language caused by brain damage. The key to understanding the nature of aphasic symptoms is the neuro-anatomical site of brain damage, and not the causative agent. However, because "Herpes simplex" virus (HSV) encephalitis infection usually affects the frontal and temporal lobes, subcortical…

The functional architecture of the verbal processing resource system was studied by testing aphasic patients in Canada and Boston for their abilities to use syntactic structure in sentence comprehension in isolation and under dual-task conditions. Results indicate that the processing resource system underlying syntactic processing is separate from…

Compares speech-related (coverbal) gestures in brain-damaged patients (aphasics and visuo-spatial deficits) and in matched controls. Results suggest ideational gestures probably facilitate word retrieval and reflect transfer of information between propositional and non-propositional representations during message construction, and that conceptual…

This article presents the case study of a cooperative Web-learning environment--SOCRATES--to foster barrier-free learning on the Web. While the growth of the Internet was exponential in the last years, still many communities don't benefit from Web-learning technology due to improper tools and constricted communication processes. These problems…

The Mackworth wide-angle reflection eye camera was used to record the position of the gaze on a display of 16 white symbols. One of these symbols changed to red after 30 seconds, remained red for a minute of testing, and then became white again. The subjects were 10 aphasic children (aged 5-9), who were compared with a group of 10 normal children,…

Aphasic (N=15) and non-brain-damaged adults were administered the Nelson Reading Skills Test (NRST). NRST items requiring complex inferences were more difficult than items requiring simple or no inferences. Passage dependency level was higher compared to other tests, suggesting that the NRST more validly measures aphasics' multiple-sentence…
