Abstract
This study was to identify a classification between hidden emotion and expressing internal emotion through pupil response analysis to complement limitation of previous studies that classified hidden emotion using facial expression. In order to better understand the underlying physiological mechanism, we measured the pupil responses under different conditions as hidden emotion and expressing internal emotion. During the experiment, Participants imagined and expressed positive or negative emotion in accordance with the instructions of the experimenter. The physiological signals such as pupil size, eye blink were measured and analyzed. There was a significant difference between the two conditions. The results showed that pupil size increased in hidden emotion than expressing internal emotion, whereas eye blink decreased. The results obtained in present study could be used as an important element of hidden emotion classification.
