In the context of emotional processing, what role do facial expressions play according to the facial-feedback hypothesis?

The facial-feedback hypothesis suggests that facial expressions play a significant role in emotional processing by acting as triggers for emotional experiences. According to this hypothesis, the act of making a specific facial expression can actually influence an individual's internal emotional state. For instance, if someone smiles, the facial feedback from that smile may enhance feelings of happiness, while frowning can intensify feelings of sadness or anger. This indicates that facial expressions are not just passive reflections of emotions; they actively contribute to how we experience those emotions.

This perspective underscores the interconnectedness of emotion and expression, implying that altering one's facial expressions can potentially shift emotional states. For example, engaging in activities that promote smiling can help in mood enhancement through this feedback loop. Thus, the facial-feedback hypothesis highlights the active role of facial expressions in the emotional experience rather than viewing them solely as external signs or communications of feelings.
