Question

According to the Cannon-Bard theory of emotion, the arousing stimulus first triggers the physical response, then the subjective experience of emotion follows.

Answer 1

I think that the question is whether the statement above is true, and the answer is: no, it's false.

The Cannon-Bard theory says that we experience the emotion  and the physical response (such as trembling or sweating in the case of fear) at the same time, that is, neither comes earlier than the other.

Answer 2

The statement is false.

The Cannon-Bard theory of emotion holds that stimulating events trigger both feelings and physical reactions at the same time.

When a stimulating event occurs, the thalamus simultaneously sends signals to the amygdala, which generates an emotional response (fear, pleasure, anger, etc.), and to the autonomic nervous system which generates a physical response (Shaking, sweating, etc.); it might also send signals to the cerebral cortex, which controls conscious thought.
