One of the most internationally used instruments for evaluation of Working Memory (WM) is the Auditory N-Back Task. In Brazil, resources to evaluate this system are scarce. The aim of this study is to investigate the performance of different age subjects in auditory n-back tasks. We divided the 102 subjects in four groups: 27 children, 22 adolescents, 26 young adults and 27 older adults. The results demonstrate an age-related difference in the n-back task performance. The accuracy increased in the transition from childhood to adolescence and kept growing from adolescence to adulthood. We also found a decrease in the performance of aged subjects. The Auditory N-Back Task results are in agreement with WM development trajectory, and so, it demonstrates to be an adjusted instrument to evaluate this system in experimental setting.
