Abstract

To investigate the performance of n-back activities of second grade elementary students, this study conducted activities for 20 minutes for four weeks by mainly giving them internal motivation. As a result of activity performance, students did not improve their n-back acquisition level significantly, but on average they kept more than 3-back level everyday except the first day of activity performance. Since thelevel maintenance is also important in the n-back activity, this process can serve as a basis for introducing the n-back activity to improve the working memory of second grade elementary students. In this study, there were individual differences in the daily acquisition levels which seemed to be attributed to individual differences in internal motivation. Thus, it is needed to be prepared the additional motivation inducement method considering the individual differences.
