Figure 3: (a) The amount of change in imagery times. In the RHL subgroup, the amount of change in imagery times was significantly larger in the other-observation (OO) condition than in the self-observation (SO) condition. In the LHL subgroup, the amount of change in imagery times was significantly larger in the SO condition than in the OO condition. In the comparison between subgroups, the amount of change in imagery in the OO condition was significantly larger in the RHL subgroup than in the LHL subgroup. The error bars represent the standard error. Significant difference (P<0.05). (b) The amount of change in execution times. In the RHL subgroup, the amount of change in execution times was significantly larger in the OO condition than in the SO condition. The error bars represent the standard error. Significant difference (P<0.05). (c) The kinesthetic and visual imagery questionnaire (KVIQ) visual subscore. The error bars represent the standard error. (d) The KVIQ kinesthetic subscore. In the RHL subgroup, the KVIQ kinesthetic subscore was significantly larger in the OO condition than in the SO condition. The error bars represent the standard error. Significant difference (P<0.05).
