The role of uncertainty and prediction error in emotional intensity: Evidence from behavioral, eye-tracking, and fMRI studies

Uncertainty and prediction error are considered important factors influencing the generation and change of emotions and may further shape individual emotional intensity. Previous studies have pointed out that emotional intensity may be related to the combined effects of valence and arousal. However, systematic evidence is still lacking regarding how uncertainty and prediction error affect the valence, arousal, and intensity representation of emotions. This study employed an adapted version of the card gambling task and, through two experiments, systematically examined the mechanisms by which uncertainty and prediction error influence valence, arousal, and emotional intensity.
