Final answer:
The James-Lange theory suggests that our conscious experience of an emotion is triggered by the physiological arousal that occurs when we have an emotion.
Step-by-step explanation:
The James-Lange theory of emotion asserts that emotions arise from physiological arousal. According to this theory, our conscious experience of an emotion is triggered by the physiological changes that occur in our bodies when we experience an emotion. For example, if you encounter a snake in your backyard, your heart racing and increased respiration would lead to the feeling of fear. Different patterns of physiological changes are associated with different emotions.
