Neural correlates of the improvement of cognitive performance resulting from enhanced sense of competence: A magnetoencephalography study.

The alterations in neural activity related to the improvement of cognitive performance, which would be leading to better academic performance, remain poorly understood. In the present study, we assessed neural activity related to the improvement of task performance resulting from academic rewards. T...
