Final answer:
The James-Lange theory of emotion emphasizes the body's physiological changes leading to subjective feelings.
Step-by-step explanation:
The theory that emphasizes our body's physiological changes that lead to subjective feelings in explaining the steps in emotions is the James-Lange theory.
According to this theory, emotions arise as a result of physiological arousal. For example, if you were to encounter a venomous snake, your body's physiological changes, such as increased heart rate and respiration, would result in the experience of fear. Different physiological arousal patterns would lead to different emotions.
