Purpose : This study aims to obtain scientific data for establishing female images based on results from an evaluation of brainwaves and emotions, after applying five different forms of eyeliners on big and small eyes.
Methods : We comparatively analyzed coefficients of variations for the brainwaves and average preference indexes (API) of 60 males and females (age 21?29), after applying five different kinds of eyeliners on big and small eyes.
Results : The brainwave responses in males and females were examined by applying five kinds of eyeliners to their big and small eyes. This showed that the activity of the γ-wave was entirely higher in people when they were stimulated by pin-up eyeliner (PU) and the α-wave was less reduced than other frequency bands. The stimulation by the forms of eyeliners, rather than by those of the eyes of the people, could be a factor influencing the brainwave responses. The active sites of the brains of the males and females were examined. The results showed that each stimulus caused prominent activity in the brain, especially in the prefrontal lobe (Fp1, Fp2, Fpz). Differences were found only in the active sites and the degree of activity among their responses to each stimulus, but their response trends were similar. The API responses by various forms of eyeliners indicated negative emotional responses only when the eyes of the people were stimulated by PU, while the other API responses indicated positive emotional responses.
Conclusion : The results of the comparative analysis on differences in brainwave and emotional responses, by applying different forms of eyeliners to people with big and small eyes, are thought to suggest a basic direction for expressing facial images. Therefore, it would be possible to collect huge scientific data for establishing female images, if the correlation among physiological and emotional responses can be drawn by applying eyeliners to people with big and small eyes.
