The study compared the brain activation patterns associated with the comprehension of written and spoken Portuguese sentences. An fMRI study measured brain activity while participants read and listened to sentences about general world knowledge. Participants had to decide if the sentences were true or false. To mirror the transient nature of spoken sentences, visual input was presented in rapid serial visual presentation format. The results showed a common core of amodal left inferior frontal and middle temporal gyri activation, as well as modality specific brain activation associated with listening and reading comprehension. Reading comprehension was associated with more left-lateralized activation and with left inferior occipital cortex (including fusiform gyrus) activation. Listening comprehension was associated with extensive bilateral temporal cortex activation and more overall activation of the whole cortex. Results also showed individual differences in brain activation for reading comprehension. Readers with lower working memory capacity showed more activation of right-hemisphere areas (spillover of activation) and more activation in the prefrontal cortex, potentially associated with more demand placed on executive control processes. Readers with higher working memory capacity showed more activation in a frontal-posterior network of areas (left angular and precentral gyri, and right inferior frontal gyrus). The activation of this network may be associated with phonological rehearsal of linguistic information when reading text presented in rapid serial visual format. The study demonstrates the modality fingerprints for language comprehension and indicates how lowand high working memory capacity readers deal with reading text presented in serial format.

ResumoEste artigo aborda o desempenho de crianças em fase de alfabetização em testes de leitura, um eixo do projeto ACERTA. O projeto busca a identificação precoce de transtornos de aprendizagem, mais especificamente, a dislexia. Neste artigo, discutimos os resultados dos testes de leitura e escrita aplicados em escolas de Porto Alegre, os quais auxiliam na identificação de crianças em risco de apresentarem dificuldade inesperada para leitura. Os objetivos específicos deste artigo são: a) verificar o desempenho das crianças em fase de alfabetização em testes de leitura e escrita e b) identificar as dificuldades persistentes que possam ser indicativas de risco de transtorno de aprendizagem. Analisamos os resultados da Provinha Brasil, do ditado ortográfico e da leitura de palavras e pseudopalavras. Os resultados são apresentados a partir de uma perspectiva ainda descritiva da amostra.Palavras-chave: avaliação de leitura; alfabetização; dislexia. The performance of children learning to read in reading and writing assessments AbstractThis paper is about the performance of children learning to read in reading tests, one of the axes of the project ACERTA (Evaluation of Children at Risk for Learning Disabilities, in Portuguese). The project aims to establish early identification of learning disabilities, more specifically, dyslexia. In this paper, we discuss the results of reading tests made in schools, which help to identify children at risk for the unexpected difficulty learning to read. The specific objectives of this study are: a) to verify the performance of children in literacy stage in reading and writing tests and b) identify the persistent difficulties that may be indicative of learning disorder risk. We analyze, specifically, the results of the tests: Provinha Brasil, spelling test and word/pseudoword reading. The test results are presented with the goal of describing the results from the first years of the project.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
