Final answer:
The facial feedback hypothesis is the theory that facial expressions can influence emotional experiences.
Explanation:
The theory that states that sensations from facial expressions help define what emotion a person feels is the facial feedback hypothesis. This hypothesis suggests that not only do our facial expressions provide a means for others to perceive our emotions, but they also contribute to the subjective experience of those emotions within ourselves. Fritz Strack and his colleagues (1988) conducted experiments which supported this hypothesis, showing that the physical act of smiling or frowning can affect the emotional response to stimuli.
