Abstract

Neurolinguistics, which researches the relationship between language and brain, also deals with language disorders. One of these language disorders is aphasia which results from a damage in the left hemisphere of the brain. Perseveration, which results from aphasia defined as the deficiency or inability of the brain functions, is a significant problem occurred in aphasia. Perseveration, known as the inappropriate and aimless repetition of an earlier response, intervention, continuation and repetition of the previous responses for an expected response, has been studied for ages. The aims of this study are to find out the relationship between perseveration and aphasia types, the importance of length of time after aphasia, to determine the rate of perseveration in naming and repetition functions, and identify the most common type of perseverations in Turkish Aphasic patients’ speech. 10 fluent and 16 non-fluent patients diagnosed with aphasia in Dokuz Eylül and Ege Universities, consist of the database of this study. Firstly, the patients were tested by Ege Aphasia Test for a general language evaluation and then a Picture/Word Scale was prepared to determine perseverations in the patients’ speech. The results were analysed according to the aims of the study and evaluated by statistical analyses. It was found that aphasia types and the length of time after aphasia had no effect on perseveration. Comparing the naming and repetition activities, it was seen that more perseveration was done in naming activities and determined that the most common types in aphasic patients’ speech were continuous and recurrent perseverations.
