Fig. 4.

The self-reported questionnaires changes among the three groups. The left half shows the RRS scores reported by different groups of participants at Pre-test and Post-test, with the red dots representing the Mean and the gray shadows representing the standard deviations. The right part shows the group comparison of RRS difference scores between Pre- and Post-tests (i.e., RRS reduction). The EWM-T group showed the greatest RRS decrease, while the WM-T group also had some effect compared with the control group. The error bars of the right part represent 95% confidence interval, **: p < 0.01.
