The digit span test is widely used to assess attention-concentration and working memory. No entanto, sua utilidade e validade ecológica são questionáveis para aqueles com baixa escolaridade e letramento, requerendo pesquisas futuras.ĭigito span memória de trabalho tarefa span idosos Nosso estudo demonstra claramente que o teste de amplitude de dígitos pode ser útil para participantes instruídos. Participantes com baixa escolaridade muitas vezes enfrentaram difficuldades com o teste de amplitude de dígitos e recorreram a adivinhar os dígitos. Os resultados indicaram que os participantes com alto nível de escolaridade tiveram desempenho significativamente melhor do que os participantes com baixo nível de escolaridade no teste de amplitude de dígitos. Todos os participantes da pesquisa foram selecionados usando uma entrevista semiestruturado, MINI Screen modificado, versão indiana do Mini Mental State Examination, uma medida de atividade da vida diária e teste do span de dígitos administrados verbalmente. Métodos:ĭuzentos e cinquenta e oito idosos saudáveis normais residentes na comunidade formaram a amostra deste estudo. Objetivo:Įste estudo explora a utilidade do teste de amplitude de dígitos para idosos indianos com diferentes níveis de educação. No entanto, a validade cultural deste teste, particularmente na população idosa indiana, não está bem estabelecida. É um teste portátil, relativamente livre de cultura e frequentemente usado. O teste de span de dígitos é amplamente utilizado para avaliar a atenção e a memória de trabalho. However, its usefulness and ecological validity is questionable for those with low education and low literacy, warranting future research.ĭigit span working memory span task older adults Our study clearly demonstrates that the digit span test can be useful for educated participants. Participants with low education often struggled with the digit span test and resorted to guessing the digits. The results indicated that participants with higher educational level performed significantly better than low-educated participants on the digit span test. All study participants were screened using a semi-structured interview schedule, the modified MINI Screen, the Indian version of the Mini-Mental State Examination, a measure of activities of daily living and the digit span test administered verbally. Two hundred and fifty-eight community-dwelling healthy normal older adults formed the sample of this study. This study explores the usefulness of the digit span test for Indian older adults with different levels of education. However, the cultural validity of this test, particularly in the Indian older population, is not well established. It is a portable, relatively culture-free and frequently used test. The size of an expert's vocabulary of chess-related configurations was estimated to be an incredible 50,000 to 100,000 chunks! Using a type of brain scanning known as functional magnetic resonance imaging (fMRI), we have shown that the lateral prefrontal cortex contributes to our ability to chunk information (Bor et al., 2003).The digit span test is widely used to assess attention and working memory. These experts seem to use their knowledge to create meaningful chunks, consisting of several chess pieces, thereby increasing the capacity of their visuospatial memory. In one study, chess masters were shown a chess board configuration for only a few seconds and were much more able to accurately recreate the same configuration than non-expert players (Simon & Gilmartin, 1973). It is this process that is thought to underlie the expert abilities of chess masters. Chunking involves recoding items into memorable clusters of information.
Our research, and several classic studies in the neuroscientific literature, have shown that visuospatial memory can be improved through "chunking" strategies.
