Facial feedback hypothesis (Niedenthal, 2007)
The configuration of facial muscles sends signals back to the brain that can alter subjective feelings and cognitive evaluations
Strack, Martin and Stepper (1988)
Participants rated cartoons funnier when holding pen between teeth (activate smiling muscles, zygomaticus major) compared to holding between lips (inhibiting smiling)
Suggests smiling can enhance positive emotion and how stimuli are judged
Coles et al. (2019)
Facial feedback effects generally small + variable especially when aware of being recorded
Multi-lab replication (Coles et al., 2022) confirmed facial feedback can increase happiness but only through facial mimicry or voluntary smiling, not pen in mouth method
Facial feedback impact
Modest but real influence on emotional experience and judgement
Strength depends on context and awareness
