Final answer:
The Cannon-Bard theory asserts that emotions and physiological responses occur simultaneously and independently in response to a stimulus.
Step-by-step explanation:
The theory of emotion that supports the idea that emotions and bodily responses occur simultaneously is the Cannon-Bard theory.
The theory posits that when you see an emotionally relevant stimulus, such as a venomous snake, you will experience fear at the exact same time as your body initiates the fight-or-flight response.
This means that your emotional response to the snake is not dependent on your body's physiological state, but rather, the two occur independently and at the same time.
