[Effect of the factor "frequency of words" on temporal and structural characteristics of speech reaction in patients with motor-efferent and motor-afferent aphasia].
The effect of the factor "Frequency of the words" on the speech and the structure of the actualised verbal responses in patients with motor aphasia has been studied. It was established that the rate of the verbal associations occurence depended on the frequency of the word-stimulus and on the probable frequency of the response - stimuli with low frequency prolong the time of the actualisation, especially of the period of sound realisation. Alterations in the psycholinguistic structure of the associative responses were detected - the percentage of the syntagmatic links in both forms of motor aphasia diminished in stimuli with low frequency, which showed that the difficulties in the processes of combination increased. In repeating, reading aloud, writing to dictation with and without pronouncing low frequency words, the number of the mistakes increased and parallel to that the possibilities for their correction decreased. In words with high frequency, reverse correlation to these mentioned above have been established. The results from the study suggested that in preparing the program for the reparative education in patients with motor aphasia, we could rely not only on the "round-about ways" for the reconstruction of the impaired speech system, but also to enlarge considerably the support of its "preserved links". Such a "link" undoubtedly is the considerably preserved speech content of high frequency words.
