  2. Emotion • Emotion • a response of the whole organism • physiological arousal • expressive behaviors • consciousexperience

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

  4. 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

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

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

  7. Cognition and Emotion • The brain’s shortcut for emotions

  8. Two Routes to Emotion

  9. Autonomic nervous system controls physiological arousal Sympathetic division (arousing) Pupils dilate Decreases Perspires Increases Accelerates Inhibits Secrete stress hormones Parasympathetic division (calming) Pupils contract Increases Dries Decreases Slows Activates Decreases secretion of stress hormones EYES SALIVATION SKIN RESPIRATION HEART DIGESTION ADRENAL GLANDS Emotion and Physiology

  10. Arousal and Performance • Performance peaks at lower levels of arousal for difficult tasks, and at higher levels for easy or well-learned tasks

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

  12. Emotion--Lie Detectors • 50 Innocents • 50 Thieves • 1/3 of innocent declared guilty • 1/4 of guilty declared innocent (from Kleinmuntz & Szucko, 1984)
