To investigate the performance of propagation speed analysis of EEG under the emotional stimuli using smartphone. Twenty-three healthy subjects were assessed for their anxiety states using CMI and divided to two groups: low CMI score (I) or high CMI score (II, III and IV) group. EEG was measured under emotionally stimuli (relaxed and pleasant, unpleasant and unpleasant sentence sessions) stimuli and analyzed using propagation speed analysis. The propagation speed for all session in the high CMI score group had a significantly region at left and right temporal and occipital regions. And the propagation speed for all session in the low CMI score group had a significantly region at frontal region. Especially, all stimuli of the low CMI score group were propagated in a longitudinal direction. The propagation speed for all session in the low CMI score group had a significantly higher than propagation speed in the high CMI score group. These processes in the brain would affect the event that stresses on human relationships that often cause people to suffer from mental disorders.
