Abstract
Emotion ensemble judgement refers to the cognitive process by which individuals extract the general emotional tone of a busy visual scene. This study investigated whether emotion ensemble judgement can be changed through cognitive training. Two groups of participants underwent interpretation and visual attention training towards positivity, respectively, while the third group served as the control (total n = 102). All three groups participated in an emotion ensemble-rating task where they rated the overall emotion of a set of facial expressions three times (pre-training, immediately post-training and 7-days post-training). The results demonstrated the malleability of perceptual judgement of an emotion ensemble. The interpretation-training group exhibited a shift towards positivity, particularly for fearful ensembles. Similarly, the attention-training group also showed a positive shift, along with increased eye movements towards happy stimuli immediately after training. These findings help shed light on the formation and correction of biases in emotion perception and judgement.
