Answer:
Charles Darwin
Explanation:
The facial feedback hypothesis states that facial movement can influence emotional experience.
He suggested that physiological changes caused by an emotion had a direct impact on that emotions, rather than being just the consequence of that emotion. He wrote:
"The free expression by outward signs of an emotion intensifies it. On the other hand, the repression, as far as this is possible, of all outward signs softens our emotions... Even the simulation of an emotion tends to arouse it in our minds."
