Theories of emotion explore how we experience and understand feelings. One prominent theory is the James-Lange Theory, which suggests that emotions arise from physiological responses to stimuli. For example, if you see a bear, your body might tremble, and you interpret that trembling as fear. Another important theory is the Cannon-Bard Theory, which posits that emotions and physiological reactions occur simultaneously but independently. According to this theory, seeing a bear triggers both the feeling of fear and the physical response, like increased heart rate, at the same time, rather than one causing the other.
