IF A MAD SCIENTIST WERE TO REPLACE YOUR BEST FRIENDS BRAIN WITH A COMPUTER- HOW WOULD YOU KNOW SOMETHING WAS DIFFERENT? Emotion

What is emotion? A psychological state characterized by physiological arousal and changes in expression, gestures, posture and feelings

Robert Plutchik’s 8 Basic Emotions

Cannon-Bard Theory James-Lange Theory Emotional event happens Physiological arousal + “state” of emotion Happen simultaneously Emotional event happens Physiological arousal Then… “state” of emotion Which comes first- behavior or emotion?

Two-Factor (Schachter-Singer) Theory Adds a cognitive component to emotion. Proposes that we can interpret identical physical sensations differently according to context. There are TWO FACTORS at work: physiological arousal and cognitive interpretation of arousal Think “S” for Schachter-Singer and “S” for situation Link to color afterimages Link to sensation seeking behaviors (bungee jumping)

Opponent Process Theory Are we driven to return to satisfy our needs-homeostasis? “Opposing” emotions Remember color afterimages?

The Face How accurately does the human face reveal emotion?

Paul Ekman The human face can make 7,000 different expressions. Universal “faces”  Anger  Disgust  Sadness  Happiness  Fear  Surprise

Display Rules…… Facial Feedback Hypothesis We learn when we are little how and when to display emotions If you “force” a smile- will you feel happier? If you “force” a frown- will you feel sad? What theory does this match up with? Cross Cultural research into the expression of emotion

Emotional Expression  Polygraphs (lie detectors) measure emotional biology  Facial recognition technology- Microexpressions
