A computer-based therapy for the treatment of aphasic subjects with writing disorders.

A computer-controlled rehabilitation for aphasics with writing impairments is presented. Subjects were asked to type words under dictation. Each time a letter was typed in its correct position, it was displayed on a screen. If the contrary, the error was not displayed, thus avoiding visual reinforcement of false choices. This method of rehabilitation has proved efficient as concerns typewriting. More importantly, some learning transfer to handwriting was observed at the completion of experimental training. The results showed a significant reduction in the number of misspelled words as well as in the erroneous choice and serial ordering of letters. The stability of the observed improvement is discussed in relationship to variables such as the time elapsed since brain damage and the type of writing difficulty.

[Several aspects of programming errors in the frontal syndrome].

In order to study different aspects of programming impairment, 32 patients with frontal lesions and other pathological groups were given two tasks: (a) "REY's Complex Figure" the results of which were compared to those of other graphic tasks; (b) an alternation task. The results of the first task indicate that the frontal subjects show characteristic disturbances, which are described. These patients encountered specific difficulties in the second task when the rule to be found involves asymmetrical sequences. The relationship between the different tasks and the programming impairment is discussed.

[Crossed aphasia in a right-handed patient: a report on one case (author's transl)].

The authors report on a 37 year old right-handed patient with a right rolando-parietal infarct which was manifest clinically by not only sensory-motor disorders of the left side of the body, but more especially by an expression aphasia. This observation fulfills the criteria for defining the exceptional case of crossed aphasia in a right-handed patient: aphasic destruction of language engendered by a right unilateral lesion in such a patient, without a previous history of a cerebral lesion or family history of left-handedness. Comparing the aphasic signs in this patient with the rare cases reported in the published literature shows that there is a particular pathognomonic profile, close to the type of aphasic disorganization seen in children and left-handed adults. The authors review the neuropsychopathogenic explanations for this crossed aphasia of right-handed patients.

Implicit processing of grammatical rules in a classical case of agrammatism.

The speech production of an agrammatic patient is viewed as the output of a syntactic filter which allows only nouns, verbs, and adjectives to pass. In this paper, we study the behavior of this filter in the processing of grammatically ambiguous words. Our results indicate that these words are either uttered or not as a function of their syntactic role in the sentence. Thus, the patient's oral reading of a sentence is not a concatenation of isolated words, but depends on an implicit, context-sensitive analysis. These observations bring to light a new aspect of the agrammatic's syntactic competence and may contribute to the study of psycholinguistic processes in normals.

[Rehabilitation of patients with frontal lesions].

Two patients with frontal lesions underwent re-education of the mental processes. The material used was the PM 38 test, WAIS cubes and visuo-spatial problems. The method used was based on Luria's re-education technique supplemented by a process of phasing out the controlling aids and cutting out facts for analysis. Results obtained before and after re-education in responses are described and compared. The problem of reansferring the skill acquired to other activities is discussed. The authors found that skills developed in the re-education situation to cope with a given task are not spontaneously utilised by the patient when he is again placed in a similar situation, but that a simple verbal cue from the tester is sufficient to cause this skill to be transferred. Finally, when faced with a new situation, the patient does not work out how to solve the problem, but he accepts more readily what is suggested to him by the tester.
