Final answer:
The James-Lange theory of emotion asserts that emotions arise from physiological arousal, while the Cannon-Bard theory posits that emotional experience occurs simultaneously with and independent of physiological arousal.
Step-by-step explanation:
The James-Lange theory of emotion asserts that emotions arise from physiological arousal. According to this theory, we experience emotions after our body has undergone a physiological response. For example, if you encounter a venomous snake, your heart rate and respiration would increase and only then would you experience fear. This theory suggests that different emotions are associated with different patterns of arousal.
The Cannon-Bard theory, on the other hand, posits that emotional experience occurs simultaneously with and independent of physiological arousal. According to this theory, when you see the snake, you would feel fear at the same time that your body mounts its fight or flight response, and the emotional reaction would be separate from the physiological arousal.
