Final answer:
According to the James-Lange theory of emotion, someone who felt almost no changes in heart rate and other autonomic responses would be likely to feel calm.
Step-by-step explanation:
The James-Lange theory of emotion states that emotions arise from physiological arousal. According to this theory, someone who felt almost no changes in heart rate and other autonomic responses would be likely to feel calm. This is because physiological arousal is believed to be the cause of emotions. If there are minimal physiological changes, then there would be minimal emotional response.
