This chapter from Open Social Psychology book covers the facial feedback hypothesis, i.e., the idea that facial expressions do not just express emotions but can also shape them. It opens with the classic Strack et al. (1988) study, which used the pen-in-the-mouth paradigm to show that activating smiling muscles made cartoons seem funnier. It then traces some replication studies and concludes that the facial feedback effects are small, sensitive to context, and not consistent across all types of manipulations.
