Individual alpha peak frequency (iAPF) during action observation and motor imagery. The highly familiar ballet dance group showed faster iAPF during the AO task relative to both non-ballet dance (p = 0.029) and non-dance (p = 0.018) groups, and also demonstrated faster iAPF than non-ballet (p = 0.049) and non-dance groups (p = 0.027) during the VMIQ-2 task. No significance between group effects were observed during the KMI task, and all participants had significantly faster iAPF during the VMIQ-2 task relative to the KMI task (p = 0.000).
