Resumo O treino cognitivo é um recurso possível para o aprimoramento da memória. Este trabalho busca comparar a eficácia de estratégias de treino de memória com idosos adotadas no contexto brasileiro. Pesquisou-se por estudos que apresentassem ensaios clínicos sobre efeitos de diferentes estratégias de memorização com idosos brasileiros. Realizou-se uma metanálise do tamanho de efeito (g de Hedges) das estratégias de nove estudos que resultaram com essas características. Evidenciaram-se efeitos do treino de insignificantes a moderados, mas não estatisticamente significativos, sobre as memórias de trabalho, episódica e semântica, além de moderado e significativo sobre a memória incidental. Isso indica que estudos brasileiros têm apresentado programas de treino com estratégias de memorização com efeito no máximo moderado sobre a memória de idosos.
Memory training is an alternative for cognitive improvement with elderly, currently evidenced in Brazilian research. Nevertheless, there is no verification of the differences between types of training, in order to identify the effectiveness of different strategies in intervention. Therefore, this paper seeks to compare strategies adopted in the Brazilian context. A meta-analysis was carried out, evaluating the effect size, publication bias and heterogeneity of the studies. The results indicate a statistically insignificant effect from insignificant to moderate on the worked memory subsystems, although with a moderate and significant effect on incidental memory. The presence of bias in publications and high heterogeneity between studies are indicated. Subsequent meta-analyses should associate the results with methodological characteristics of the works.
