| Abstract: | The author found that cerebral hemisphere dominance of steady-state vowels as well as human emotional and natural sounds are different between the Japanese and the Westerner; the Japanese shows a verbal hemisphere dominance, while the Westerner shows a non-verbal hemisphere dominance. He brought forward the theory of mental structure and vowels stating that such a difference in the brain related to emotional activities forms the starting point of mental structure and culture. In this study the author confirmed the above hypothesis by emotional stimulation of human olfaction. |
