CATEGORIZAÇÃO LINGUÍSTICO-COGNITIVA NAS AFASIAS E DEMÊNCIAS: UMA REVISÃO INTEGRATIVA

Abstract

The broader objective of the work is to investigate how the categorization process happens in individuals suffering from aphasia and dementia from the perspective of Cognitive Linguistics. Through an integrative review, we analyzed, preferably, papers that used experimental scientific methodology. A total of 25 scientific articles were reviewed that discussed how the linguistic-cognitive activity of categorization is carried out by individuals with aphasia or dementia. Based on this and the methodological choice followed in this work, the “methodology”, “results” and “discussion” sections of each reviewed article served as the main sources of results for discussion on the topic. The category view adopted in this work is that of Rosch (1978) and Lakoff (1987) and for studies on aphasia, we adopted Ortiz (2010) and Mansur and Radanovic (2003). Among the results obtained after the review, 10 types of linguistic categorization were found, researched between 3 main types of dementia, 2 main types of aphasia and other general ones, following methodological steps specific to each work or similar when the articles dealt with the same type of category. The main results of each article and the possible relationship between the effects of cognitive deficit on the categorical process are discussed. The results of this work conclude that, in the vast majority, individuals with aphasia or dementia suffer a higher cost or similar to the typical population in the production and comprehension processes when they are categorizing, therefore presenting a cognitive deficit, specifically, aphasia or dementia can interfere in linguistic activities that require the use of neurocognitive work.
