This investigation examines in aphasics the loss of the ability to relate words to their grammatical categories. It finds that recognition of grammatical categories is lost in all forms of aphasia studied, but that the loss is manifested differently for different types of aphasia quantitatively and qualitatively.

Agrammatism, the disruption of the grammatical structure of speech, is studied in its accompaniment to aphasia. Since it occurs with all studied forms of aphasia, it is considered here a symptom typical to aphasia. It is also examined in relation to different kinds of aphasics. (SCC)

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)

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)

The study summarized in this paper deals with the grammatical analysis of the spontaneous speech of approximately 150 children who are classified as mentally disabled; educable (I.Q. range 50-80). The performance of these mentally disadvantaged children is compared with the performance of 200 normally developing children by using a clinical…

This paper is concerned with the Aristotelian notion of "universal" as applied to phonological phenomena. It is claimed that speech production in children and adults, in normal and deviant speakers, and in a variety of languages, can all be described according to the same universal phonological rules which constitute the universal process of…
