What hypothesis suggests that facial expressions can influence our emotional state?

The Facial-Feedback Hypothesis posits that facial expressions can significantly influence our emotional experience. This idea is grounded in the concept that the physical act of forming a facial expression can send signals to our brain that contribute to feelings associated with that expression. For example, smiling can enhance feelings of happiness, while frowning may increase feelings of sadness or displeasure.

Research supporting this hypothesis demonstrates that participants who adopt a facial expression associated with a specific emotion often report feeling that emotion more intensely, highlighting the connection between our expressions and our emotional states. This insight reveals the dynamic interaction between our physiology and psychology, suggesting that not only do our emotions cause us to express ourselves physically, but our physical expressions can also shape our emotional experiences.

In contrast, the other theories listed focus on different aspects of psychology. Emotional Expression Theory delves into the broad nature of how we convey emotions, but does not specifically address the feedback mechanism. Cognitive Dissonance Theory relates to the discomfort individuals feel when holding conflicting beliefs or attitudes. Finally, Social Comparison Theory centers on how individuals assess their own worth based on comparisons with others, which is distinct from the direct link between facial expression and emotional experience.
