Literacy as a determining factor for brain organization: from Lecours' contribution to the present day

A alfabetização como um fator determinante na organização do cérebro: da contribuição de Lecours à atualidade

Abstracts

Abstract - This review aimed to discuss the influence of literacy and formal education on human brain organization, based on evidence drawn from three sources: (1) results and limitations of a project coordinated by André Roch Lecours on the influence of illiteracy on brain organization and of studies on aphasia in illiterate populations; (2) data on the impact of schooling on the neuropsychological assessment of healthy and brain-damaged individuals, and (3) studies on the effect of schooling on dementia. These findings suggest that schooling and literacy processes influence cerebral organization of healthy individuals, as well as of brain-lesion individuals and those with dementia. Concerning illiteracy, the systematic pioneering studies developed by Lecours and the continuity of his investigations were essential to alert the scientific and clinical communities to take into account the role of educational experience on cognitive processing and its brain substrates.

Key words:
literacy; education; human cognition.


Resumo - Esta revisão tem por objetivo discutir a influência da alfabetização e da educação formal na organização do cérebro humano, com base em evidências aportadas por três fontes: (1) resultados e limitações de um projeto coordenado por André Roch Lecours sobre a influência do analfabetismo na organização cerebral e de estudos sobre afasia em populações analfabetas; (2) dados sobre o impacto da escolaridade na avaliação neuropsicológica de indivíduos saudáveis e com lesão cerebral, e (3) estudos sobre o efeito da escolaridade na demência. Tais achados sugerem que processos de escolaridade influenciam a organização cerebral de indivíduos saudáveis, bem como a de indivíduos com lesão cerebral e com quadro de demência. Com relação ao analfabetismo, os estudos sistemáticos pioneiros de Lecours, bem como a continuidade de suas investigações, foram essenciais para alertar as comunidades científicas e clínicas quanto à necessidade de considerarem o papel da experiência educacional no processamento cognitivo e em seus substratos cerebrais.

Palavras-chave:
alfabetização; educação; cognição humana.
