Sintomatologia depressiva e eficiência no n-back

Abstract

A memória de trabalho diz respeito a uma pequena quantidade de informação que é armazenada e mantida na mente apenas pelo tempo que for necessário. Neste estudo em particular, pretende-se explorar a influência que a sintomatologia depressiva tem sobre um componente específico da memória de trabalho, o executivo central, através da realização de uma tarefa, a n-back task. Esta última tarefa é uma das mais utilizadas na avaliação da memória de trabalho. Foi avaliado o desempenho dos participantes através de possíveis diferenças estatísticas na velocidade de resposta e nas taxas de acerto relativamente à n-back task. Foi utilizada uma amostra por conveniência, de pessoas entre os 18 e os 52 anos, um questionário sociodemográfico, o BSI – inventário de sintomas breves e a n-back task. De uma maneira geral, não foram encontradas diferenças significativas entre os grupos com níveis mais altos e níveis mais baixos de sintomatologia, relativamente à taxa de acertos e dos tempos de resposta na realização da n-back task, e, assim, nenhumas das hipóteses deste estudo se comprovou.

Working memory refers to a small amount of information that is stored and kept in the mind only for as long as necessary. In this study it is explored the depressive symptom’s influence on a specific working memory component, the central executive, through n-back task performance. This task is one of the most used in the assessment of working memory. Reaction times statistical differences were assessed. Sample was composed by people aged between 18 and 52 years assessed by a sociodemographic questionnaire, BSI – Brief Symptom Inventory and the n-back task. In general, no significant differences were found between the groups with higher and lower levels of symptomatology, regarding the rate of correct answers and reaction times in performing the n-back task, and thus none of the hypotheses of this study proved itself.
