Theories of Emotion Does your heart pound because you are afraid... or are you afraid because you feel your heart pounding?

Emotion Willam James and Carl Lange came up with the James-Lange Theory of Emotion. We feel emotion because of biological changes caused by stress. The body changes and our mind recognizes the feeling.

James-Lange Theory of Emotion Experience of emotion is awareness of physiological responses to emotion-arousing stimuli Fear (emotion)‏ Pounding heart (arousal)‏ Sight of oncoming car (perception of stimulus)‏

James-Lange (cont.) Subjects report feeling more sad when viewing scenes of war, sickness, and starvation if their “sad face” muscles are activated. They also find comic strips funnier if their “happy face” muscles are activated.

Cannon-Bard Theory of Emotion The physiological change and cognitive awareness must occur simultaneously. They believed it was the thalamus that helped this happen.

Cannon-Bard Theory of Emotion Sight of oncoming car (perception of stimulus)‏ Pounding heart (arousal)‏ Fear (emotion)‏ Emotion-arousing stimuli simultaneously trigger: physiological responses subjective experience of emotion

They happen at the same time but… People who are already physiologically aroused experience more intense emotions than unaroused people when both groups are exposed to the same stimuli. Biology and Cognition interact with each other to increase the experience.
