What theory of emotion best applies to the facial feedback hypothesis and why? How is this related to the Schacter-Singer two-factor theory?

The emotion theory that is best applied to the facial feedback hypothesis is the so-called sensory feedback, which was carried out by facial muscles and skin sensations, since they can produce an emotional experience without the need for cognitive mediation .

The Schacter-Singer theory is related to the theory of facial feedback in which it is established that the beginning of emotions comes, on the one hand, from the interpretation made of the physiological responses of the organism, and in addition to the cognitive examination of the situation, and on the other hand, what causes these physiological responses.

Explanation:

The hypotheses of facial feedback have antecedents in some theories in which the activation of muscles with the subjective practice of emotions are prioritized. For example, Silvan Tomkins's theory about sensory feedback, where facial muscles, and some skin sensations played an important role that could produce an emotional state without the need for cognitive intercession.

The intensity of emotions is that in how physiological responses are interpreted and the quality of emotion is explicit in the way in which the situation that induced these responses is examined in a cognitive way.
