James-Lange theory of emotion

The James-Lange theory of emotion suggests that emotions result from our physiological reactions to events. According to this theory, when we encounter a stimulus—like seeing a snake—our body reacts first, such as through increased heart rate or sweating. We then interpret these physical responses, which leads us to experience the emotion, like fear. In essence, the theory proposes that we feel emotions because of our bodily changes, not the other way around. So, instead of feeling fear and then shaking, we shake and then feel fear.
