| Abstract(in English) | A form of emotional suppression is defined as the conscious inhibition of emotional-expressive behaviors while emotionally aroused. In human-to-human interaction, there is a problem that if speakers suppress their emotions, their internal affective states cannot be expressed to the interlocutor. We propose a new recognition technique of emotional suppression that human may not perceive. In this study, in order to detect suppression of negative emotion, we used Functional Near-Infrared Spectroscopy, and measured cerebral blood flow during watching and speaking with neutral and disgust emotions. For the time series data of cerebral blood flow, we performed a statistical test to confirm whether there is a significant difference in the mean value and changes in cerebral blood flow between each emotion. Then, we tried to apply classification models to automatically detect suppressed emotions. Results showed that our models could correctly detect the suppressed emotions over 70% accuracies. |
