The effects of arousal and valence on facial electromyographic asymmetry during blocked picture viewing
The effect of stimulus valence and arousal on facial electromyographic (EMG) asymmetry was investigated to inform the debate about two contrasting hypotheses of emotion: the right hemisphere dominance hypothesis and the valence hypothesis. EMG was recorded from the left and right corrugator and zygo...
