The purposes of this research were to design emotional valence of picture and digitized sound task and then to study emotional valence, pleasurable and unpleasant emotions classified by gender and personality. Participants were 80 undergraduate students in the academic year 2017 at Burapha University. Research instruments included the emotional valence picture and digitized sound task, and Self-Assessment Manikin (SAM). Data were analyzed using a two-way analysis of variance.
The results showed that:
1. The task consisted of two blocks of pictures and digitized sounds: pleasurable and unpleasant emotions. Each block contained 12 stimuli and each stimulus was presented for 14.5 seconds.
2. Gender and personality differences significantly affected pleasurable emotion (p<.05). However, the difference in unpleasant emotion was not found.
3. There was an interaction effect between genders and personalities on emotional valence both in pleasurable and unpleasant emotions (p<.05).
