Fear can be applied to three theories, the James-Lange Theory, Cannon-Bard Theory, and the Two-factor Theory

Physiological characteristics of fear such as a racing heart that is experienced first, then the emotion fear shows the concept of James-Langes theory. When our bodily reactions to a stimulus comes before the emotion it demonstrates this theory.

When sweating occurs at the same time of feeling the emotion fear, this would demonstrate Cannon-Bard Theory because the bodily reaction and emotion are happening at the same time but are separate from each other. This is because the brain sends neural impulses to other parts of the brain and the autonomic nervous system (at the same time).
