Purpose: This study aimed to create image maps and understand the correlation between electroencephalography (EEG) and emotional responses by presenting a stimulus with modified forms of eyeliners to 30 males and 30 females aged in their 20s.
Method: The coefficient of variation for the brain wave (CVB) and favorability for and average preference index (API) of the eyeliners were examined. The correlation between brain waves and favorability was analyzed and an attempt to position the resulting API on an adjective image map was made. Statistical analysis of EEG and emotional evaluation was performed using SPSS, followed by repeated measure analysis of variance and post-test with Turkey's test at 95% confidence level.
Results: When the EEG responses of the male and female participants were stimulated by no-eyeliner (NL), the α-wave was less reduced; when the EEG responses were stimulated by pin-up eyeliner (PU), β-wave, and γ-wave, SEF50 and SEF90 were most notably activated. Both instances showed similar EEG responses and APIs, depending on the variation in eyeliner forms. Although there was a low correlation between each form of eyeliners and favorability and API, there was a high correlation between API and SEF50 for both. On the adjective image map, the API of PU was evenly distributed in the range of positive and negative images for male and female participants, and they were entirely evaluated as strong and dynamic ones. Both the male and female participants demonstrated favorability for the basic eyeliner (BC) form of the eyeliners, followed by arabic eyeliner (AA) and NL.
Conclusion: The results of the EEG and emotional responses, depending on the variation in eyeliner forms, suggest a basic direction of face image expressions. This technology could acquire scientific data for prospective image building of women, if correlations among physiological and emotional responses can be drawn, by applying eyeliners to various eye-shapes.
