Moreover, a strong trend for a reduction in performance error SD was found after compared to before the display of feedback [ t (19) = 2.395, p = 0.054].
Moreover, a strong trend for a reduction in performance error SD was found after compared to before the display of feedback [ t (19) = 2.395, p = 0.054].
For each participant we calculated the extent of improvement in the task as the difference between performance error SD during and before feedback (which showed a highly significant difference, above).
