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

4. 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.

8. 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)‏

9. 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.

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

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

14. Two-Factor Theory of Emotion http://www.youtube.com/watch?v=e2qdvELqskc http://www.youtube.com/watch?v=e2qdvELqskc  Stanley Schachter explains emotions more completely that the other two theories.  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.

18. Schachter’s Two Factor Theory of Emotion  To experience emotion one must:  be physically aroused  cognitively label the arousal Cognitive label “I’m afraid” Fear (emotion)‏ Sight of oncoming car (perception of stimulus)‏ Pounding heart (arousal)‏
