Sentence comprehension and grammaticality judgment were studied in 10 healthy subjects and 10 agrammatic aphasic stroke patients. The latter were able to make grammaticality and comprehension judgments, but less accurately. Results indicated that such judgments are made using different processes and/or operate on different aspects of language…

Issues concerning the teaching of sign systems to severely communicatively handicapped persons are considered. It is explained that the differences causing severe communication handicaps will affect which aspects of language processing and which aspects of language will be affected. Suggestions are made as to why some individuals who have great…

Reviews cases which support the view that parts of the left hemisphere control languages, no matter how it is expressed, while right-side regions are involved only in skilled nonlinguistic movements and perceptions. Compares recent findings with previously held theories. (ML)

The order of acquisition of a set of linguistic structures and the relationship between structures were examined over 5 years in 28 language-impaired children (age 4) and 32 language-matched normal children. Results demonstrated a marked similarity between groups, suggesting that the linguistic impairments may be principally processing, not…

Three objectives of research reported here were to describe the neural organization underlying language usage and language loss, to study activities occurring in both cerebral hemispheres, and to study neural changes related to changes in syntactic complexity of stimuli. A dichoptic procedure was chosen. A subject faced a viewing screen on which…

This study deals with word retrieval problems of aphasic patients. This word-finding difficulty is a common characteristic of aphasics and many methods have been used by aphasia clinicians to attempt to remediate word retrieval skills. Cueing, one of the methods used, presumably facilitates word-finding by supplying additional information to the…
