Facial expressions elicit multiplexed perceptions of emotion categories and dimensions.

ABSTRACT: Human facial expressions are complex, multi-component signals that can communicate rich information about emotions,^1-5 including specific categories, such as "anger," and broader dimensions, such as "negative valence, high arousal."^6-8 An enduring question is how this complex signaling is achieved. Communication theory predicts that multi-component signals could transmit each type of emotion information-i.e., specific categories and broader dimensions-via the same or different facial signal components, with implications for elucidating the system and ontology of facial expression communication.⁹ We addressed this question using a communication-systems-based method that agnostically generates facial expressions and uses the receiver's perceptions to model th
