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…

Results of a verbal sound and meaning discrimination test to check the hypothesis of Alajouanine et al.--that two types of paraphasics can be distinguished, phonemic and semantic--are discussed. The former are impaired in tests of auditory language discrimination, the latter show regression of the semantic values apparent in their linguistic…

Considering Jakobson's theory that speech disorders involve defects in paradigmatic or in syntagmatic operations, and that these two categories result in different defects, this question was examined: does the syntagmatic group suffer from defects not only in contextual generation of active speech but also in comprehension of grammatical…

This article examines the process of language comprehension by relating the question to aphasia. The premise is that the study of aphasia should lead to a better understanding of the processes involved in comprehension. (Text is in French.) (AM)

A report on results of a study of a large number of subjects afflicted with different types of aphasia. Topics reported are: an experimental study of verbal comprehension and a qualitative study of errors in standard verbal tests. Statistical tables and a bibliography are attached. (Text is in French.)

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…
