This research study aims to investigate emotional valence among young adults according to gender and personality using electroencephalography. The subjects of the study were a batch of 80 undergraduate students from Burapha University who took part in this research in 2017. The research instruments include an experimental activity where the subjects were instructed to view Thai words and pictures that arouse emotional valence among young adults. A 64-channel brainwave recorder was used to record the corresponding brain wave data (N100, N200, P300, and N400) while the subjects were viewing the Thai words and images that arouse emotional valence. The outputs were statistically analyzed using a two-way ANOVA.
The findings revealed that there were differences in emotional valence between male and female adults’ satisfaction while viewing Thai words and pictures that arouse emotion as depicted in brain waves N100, N200, P300, and N400. In contrast, male and female adults’ dissatisfaction was characterized by differences in emotional valence in brain waves N200, P300, and N400. With regards to open and average personality types, it was found that satisfaction characteristics differ in waves N100, N200, and N400, and dissatisfaction was characterized by differences in waves N200 and P300. The findings of this research indicate that Thai words and pictures that arouse emotional valence produce varying effects on the human brain with respect to gender and personality.
