  1. Emotion, p. 394-403 A response of the whole organism, involving • Physiological arousal by the autonomic nervous system • Expressive behaviors • Conscious experience

  2. Arousal and Performance Yerkes-Dodson Law • Performance peaks at lower levels of arousal for difficult tasks, and at higher levels for easy or well-learned tasks Performance level Difficult tasks Easy tasks Low Arousal High

  3. Expressing emotion • Nonverbal language and verbal language helps to express emotion. • Nonverbal communication can be universal

  4. Cultural Emotion and Expression • Gestures are sometimes culturally determined • Facial expressions for the basic emotions are universal: Joy, anger, interest, disgust, surprise, sadness, and fear

  5. Ekman universal emotions

  6. If I smile will it make me happy? • Paul Ekman found expressions amplify the felt emotion and signal the body to respond accordingly • Soooooo smile!

  7. Emotion--A Polygraph Examination

  8. Emotion-Lie Detectors • Polygraph • machine commonly used in attempts to detect lies • measures several of the physiological responses accompanying emotion • perspiration • cardiovascular • breathing changes

  9. Percentage 80 70 60 50 40 30 20 10 0 Innocent people Guilty people Judged innocent by polygraph Judged guilty by polygraph Emotion--Lie Detectors • 50 Innocents • 50 Theives • 1/3 of innocent declared guilty • 1/4 of guilty declared innocent (from Kleinmuntz & Szucko, 1984)

  10. Experienced Emotion • Catharsis • emotional release • catharsis hypothesis • “releasing” aggressive energy (through action or fantasy) relieves aggressive urges • Feel-good, do-good phenomenon • people’s tendency to be helpful when already in a good mood

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

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

  14. Cannon-BardTheory of Emotion • Emotion-arousing stimuli simultaneously trigger: • physiological responses • subjective experience of emotion

  15. Schachter’s Two Factor Theory of Emotion • To experience emotion one must: • be physically aroused • cognitively label the arousal 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.

  16. Schachter’s Two-Factor (cont.) Epinephrine Study:

  17. Schachter’s Two-Factor (cont.) • Swinging Bridge Study Would you like my phone number?

  18. Reviewing the three Emotion occurs at the same time as arousal Emotion follows (lags behind) arousal Arousal + Cognitive label  Emotion

  19. Opponent Process Theory • Feel one intense emotion, then leads to the opposite emotion. →

  20. Quiz question After being physically aroused by his daily 3-mile run, Casper finds that he experiences resentment if his wife asks for an unexpected favor and more intense romantic feelings if she kisses him. Casper’s experience can best be described by the: • Cannon-Bard theory • James-Lange theory • Two-factor theory • Opponent-process theory
