A research group led by Associate Professor Wataru Sato of the Kokoro Research Center Kyoto University has found that the Japanese expression is inconsistent with the theory of Dr. Ekman, who is well-known in psychological research.This is the world's first report on the facial expressions of the six basic emotions of the Japanese, and was published in the electronic version of the psychology magazine "Frontiers in Psychology".
According to Kyoto University, the research group surveyed 65 Japanese people.The subjects imitated the facial expression photographs created based on Ekman's theory, and also talked about the six basic emotions of anger, disgust, fear, joy, sadness, and surprise. I made facial expressions based on the specified scenario, such as "feelings when the smell of" was very bad. "
When the facial expressions were analyzed by artificial intelligence, emotions were clearly expressed in the facial expressions by imitating photographs, but in the scenario, emotions were expressed only by joy and surprise.Furthermore, it was found that the movement patterns differ depending on the imitation of the photograph and the facial expressions created according to the scenario.
Ekman theory was created based on intuition and observation, and is widely known as a subject in Western TV dramas.However, previous experiments conducted in the West, such as Canada, have shown that only part of Ekman's theory can be supported.
In Japan, the development of artificial intelligence that reads emotions from facial expression images is progressing, but the judgment is based on Ekman theory.It is expected that the development of artificial intelligence that properly reads facial expressions will progress as research on facial expressions progresses in Japan as well.
