Does Facial Expression Accurately Reveal True Emotion? Evidence from EEG Signal

초록

Facial expression is one of the ways in which human expresses emotion. However, there has been evidence that facial expression does not always accurately reflect inner emotions, leading to the shaking of theories about human basic universal emotions. In this study, we conduct an experiment to collect facial expression data and EEG signals of participant. The results indicate that not all kinds of basic emotion were expressed in facial expressions under the experiment environment. On the other hand, brain signals have proven to be a highly reliable tool for emotion recognition task. This study shows the problems faced by facial emotion recognition systems and proposes future works to improve the efficiency of those systems. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
