          Abstract

          The aim of this study was to investigate perseveration in two contexts: spontaneous language and linguistic tasks. It points toward perseveration as a theoretical linguistic conception, that is, sociointeractionist. This presupposes language activity produced in an interlocutive space and it does not neglect pragmatic aspects and contextual use of language. Four patients presenting the following types of aphasia were analyzed: motor transcortical, amnestic, semantic and sensory. The results point out different aspects between pathological perseveration and perseveration as a normal expression in the process of language activity. This study might imply another theoretical perspective of language therapy to perseveration in aphasia.

          O propósito deste estudo foi investigar a perseveração em dois contextos: linguagem espontânea e tarefas linguísticas. Esta pesquisa aponta para a perseveração como sendo uma concepção teórico-linguística, qual seja, sociointeracionista. Isto abrange atividade linguística produzida em um espaço interlocutivo e não negligencia aspectos pragmáticos e o uso contextual da língua. Quatro pacientes, apresentando os seguintes tipos de afasia, foram analisados: transcortical motora, amnéstica, semântica e sensorial. Os resultados apontam para diferentes aspectos entre perseveração patológica e perseveração, como expressão normal do processo de atividade de linguagem. Este estudo poderá implicar outra perspectiva teórica de terapia de linguagem na afasia.

          PERSEVERATION AND ACTIVATION IN APHASIC SPEECH PRODUCTION.

          This paper presents a single-case study of the speech production performance of an aphasic subject, CJ. CJ's productions included a large number of perseverations. Perseverated responses comprised real words, nonwords, and subword segments and the majority of them were unrelated to the target items (either by sound or meaning). An analysis of the determinants of perseverate responding revealed that the frequency of the target name was an important factor. Moreover, there appeared to be both a semantic and a phonological basis for perseveration. These results are used to evaluate a recent account of perseveration.

            Frequency of perseveration in normal subjects.

            Although perseveration is a recognized sign of disturbed brain function, it also occurs in normal individuals. Determination of the frequency of perseveration in normal subjects would enable clinicians to use perseveration as a marker of possible pathology. The purpose of this study was to document the extent of perseveration in normal young and older subjects. Thirty young normal individuals between the ages of 20 and 35 years and 30 older normal individuals between the ages of 60 and 75 years were given four tasks on which perseveration has been reported in brain-damaged individuals. Four percent of all responses were perseverative. No age or gender effects on frequency were observed. Of the four neuropsychological tasks, the Modified Wisconsin Card Sorting Test elicited the greatest number of perseverations.
