Resumo: The objective of the present study was to investigate reading performance and brain activation associated with reading for bilingual and monolingual dyslexics (DDB-DDM), and typical bilinguals as Controls (C). The behavioral results showed that DDB outperformed DDM in all reading components in Portuguese. In the tasks applied in English, there was no significant difference in the performance of DDB compared to C. The results of the brain imaging for the task in Portuguese showed C presented significant activation of the left occipitotemporal and left inferior frontal gyrus while reading words. DDB and DDM, in turn, showed deactivation of left temporoparietal region and no significant activation in the left occipitotemporal region or left inferior frontal gyrus. For the FAST LOC task, DDB showed hypoactivity in the Visual Word Form Area (VWFA) during word reading, both in English and Portuguese. The findings provide evidence for a possible positive impact of bilingualism on the reading performance of dyslexics.

Os resultados comportamentais mostraram que o DDB superou o DDM em todos os componentes de leitura em português. Nas tarefas aplicadas em inglês, não houve diferença significativa no desempenho do DDB em comparação com C. Os resultados das imagens cerebrais para a tarefa em português mostraram que C apresentou ativação significativa do giro occipitotemporal esquerdo e giro frontal inferior esquerdo durante a leitura de palavras. DDB e DDM, por sua vez, mostraram desativação da região temporoparietal esquerda e nenhuma ativação significativa na região occipitotemporal esquerda ou no giro frontal inferior esquerdo. Para a tarefa FAST LOC, o DDB apresentou hipoatividade na Visual Word Form Area (VWFA) durante a leitura de palavras, tanto em inglês quanto em português. Os resultados fornecem evidências de um possível impacto positivo do bilinguismo no desempenho de leitura dos disléxicos.UFSC2023-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/desterro/article/view/9452410.5007/2175-8026.2023.e94524Ilha do Desterro A Journal of English Language, Literatures in English and Cultural Studies; Vol. 76 No. 3 (2023): Experimental studies on bilingualism and language learning Ilha do Desterro A Journal of English Language, Literatures in English and Cultural Studies; v. 76 n. 3 (2023): Experimental studies on bilingualism and language learning 2175-80260101-4846reponame:Ilha do Desterroinstname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/desterro/article/view/94524/54731Copyright (c) 2023 Aline Fay, Augusto Buchweitz, Nathália Bianchini Esper , Mirna Wetters Portuguez , Asafe Davi Cortina Silvahttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFay, AlineBianchini Esper , Nathália Wetters Portuguez , Mirna Davi Cortina Silva, Asafe Buchweitz, Augusto 2024-02-23T12:55:23Zoai:periodicos.ufsc.br:article/94524Revistahttp://www.periodicos.ufsc.br/index.php/desterroPUBhttps://periodicos.ufsc.br/index.php/desterro/oaiilha@cce.ufsc.br||corseuil@cce.ufsc.br||ilhadodesterro@gmail.com2175-80260101-4846opendoar:2024-02-23T12:55:23Ilha do Desterro - Universidade Federal de Santa Catarina (UFSC)false
