Brain Waves and Emotional Responses in Males and Females Derived from the Application of Various Eyeliners to Sloe Eyes

Abstract

Purpose: To establish quantitative data through brain waves and emotional responses by applying eyeliners to sloe eyes in males and females in their twenties. Methods: This study created stimulants by applying five eyeliners to eyes whose shapes were changed by raising their tails. Using stimulants, the coefficient of variation for brainwaves and average preference indices were obtained from males and females in their twenties, and then were positioned on an adjective image map. It is also suggested how to scientifically analyze make-up images based on a correlation between preference and beta. Results: The evaluation of brain waves and emotions collected from stimulants showed that, for both males and females, a θ wave was activated using the NL stimulation, and α wave was less decreased using the AA stimulation. The activation rates of β and γ waves were most increased by PU stimulation. Although the activation of β and γ waves in males were higher than those in females, the brain wave response tendency stimulated by eyeliners was similar in individuals with both genders. The emotional responses to sloe eyes in individuals with both genders were commonly feminine. The preference indices in both males and females were high for the NL stimulation, and the valuation index of the AA simulation was also good. The preference indices of eyeliners in the males and females were low for the PU stimulation. Among the stimulants to which five eyeliners were applied, those of PU allowed regular the positioning of positive and negative images. Conclusion: There were no discrepancies in the brain waves and emotional responses of the males and females derived from stimulants of eyeliners applied to sloe eyes. The results suggest that it is possible to draw quantitative images from a make-up that is conducted based on a qualitative evaluation. If the data of correlations between emotional responses and brain waves are further collected, they would be efficiently used in the beauty industry.
