RESUMO

A idéia de que a memória não é uma entidade unitária, mas que se compõe de múltiplos sistemas independentes, porém interativos, parece atualmente consensual. Na primeira parte do presente trabalho são revistas evidências da literatura a favor da distinção entre os sistemas de memória de curta duração e de longa duração, por um lado, e a subdivisão adicional entre os sistemas de memória de longa duração, por outro. A evolução do conceito de memória de curta duração, que resultou na idéia de memória operacional, por sua vez também composta de múltiplos sistemas, é discutida, bem como o papel dos níveis de processamento no funcionamento mnêmico. Na segunda parte, são apresentados os principais modelos de organização dos sistemas de memória humana.

Palavras-chave: memória, habilidades, hábitos, neuropsicologia.

ABSTRACT

It seems a consensus nowadays that memory is not a single entity but comprehends multiple independent but interactive brain systems. The first part of this work has examined evidence, favoring the distinction between short-term and long-term memory systems, on one hand, and further subdivisions of the last, on the other. The elaboration of the concept of short-term memory, which led to the idea of working memory, composed itself of multiple systems, has also been discussed, as well as the role of levels of mnemic processing. The second part has presented the major theories concerning the organization of human memory.

Key words: memory; skills; habits; neuropsychology.
