HAPPY – THE MOVIE • Emotions • Powerpoint and video analysis
Arousal and Performance Performance level Difficult tasks Easy tasks • Performance peaks at lower levels of arousal for difficult tasks, and at higher levels for easy or well-learned tasks. • For MOST tasks though, you want moderate levels of arousal. Low Arousal High
Role of Neurotransmitters & Hormones • Important Roles in Emotion: • Low serotonin Depression. • High levels of Epinephrine and Norepinephrine Anger and Fear.
The Limbic System and Emotions • The Amygdala is a neural key to fear learning. • Also involved in rage and aggression. • Integrates the hormonal and neural emotional aspects.
Role of the Cortex and Emotions • In general… • the right hemispherespecializes in negative emotions and… • the left hemispherespecializes in positive emotions.
Theories of 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.
Cannon-Bard Theory of Emotion • They say the James-Lange theory is full of crap. • How can that theory be true if similar physiological changes correspond with drastically different emotional states. • The physiological change (body’s arousal) and cognitive awareness (emotions) must occur separately (but simultaneously). • Routed to the cortex and the Sympathetic NS at the same time by the Thalamus.
Two-Factor Theory of Emotion • Stanley Schachter explains emotions more completely that the other two theories. • They happen at the same time but… • To experience the emotion the person must be physically aroused AND cognitively label the arousal. • Biology and Cognition interact with each other to increase the experience.
Spillover Effect • When arousal spills over from one event to another. • Like when arousal from a basketball game fuels anger, which then descends into rioting or other violent confrontations.
Physiological activation Appraisal Emotional response Expressive behavior Event Subjective experience Two Routes to Emotion Lazarus/Schachter Zajonc/LeDoux
Lie Detectors • Called a polygraph. • Measures several of the physiological responses accompanying emotion: • Perspiration • Heart rate • Blood pressure • Breathing changes
Percentage 80 70 60 50 40 30 20 10 0 Innocent people Guilty people Judged innocent by polygraph Judged guilty by polygraph Lie Detectors 50 Innocents 50 Thieves --1/3 of innocent declared guilty --1/4 of guilty declared innocent (from Kleinmuntz & Szucko, 1984)
Lie Detectors Is 70% accuracy good? *Assume 5% of 1000 employees actually guilty. --test all employees --285 will be wrongly accused What about 95% accuracy? *Assume 1 in 1000 employees actually guilty. --test all employees (including 999 innocents) --50 wrongly declared guilty --1 of 51 testing positive are guilty (2%)
Expressed Emotion People more speedily detect an angry face than a happy one.

Expressing Emotion • Non-verbal communication - gestures, body language, facial expressions. • Introverts – better at reading other’s emotions. • Extroverts– easier to read.
Culture and Emotional Expression • Gestures and their meaning vary from culture to culture. • Individualist cultures show more intense and prolonged emotions. • http://www.youtube.com/watch?v=dwJ-wwF9XVs
Detecting and Computing Emotion Most people find it difficult to detect deceiving emotions. Even trained professionals like police officers, psychiatrists, judges, and polygraphists detected deceiving emotions only 54% of the time. Which of Paul Ekman’s smiles is genuine?
Culture and Emotional Expression When culturally diverse people were shown basic facial expressions, they did fairly well at recognizing them. http://www.youtube.com/watch?v=-PFqzYoKkCc https://www.youtube.com/watch?v=h19PzyqOxxo
Experienced Emotion • Infants’ naturally occurring emotions
Positive valence pleasant relaxation joy Low arousal High arousal fear anger sadness Negative valence Two Dimensions of Emotion Blue = Psychological Pink = Physiological Valence refers to the intrinsic attractiveness or aversiveness of an emotion.
Anger Anger “carries the mind away,” (Virgil, 70-19 B.C.), but “makes any coward brave,” (Cato 234-149 B.C.).
Anger • People generally become angry with friends and loved ones who commit wrongdoings, especially if they are willful, unjustified, and avoidable. • People are also angered by foul odors, high temperatures, traffic jams, and aches and pains. • If you’re angry at someone about something… tell them directly.
Anger - Cultural & Gender Differences • Boys tend to respond to anger by moving away from that situation or exercising, while girls talk to their friends or listen to music. • Anger also breeds prejudice (Like the 9/11 attacks did). • Individualized cultures encourage venting; not collectivist cultures.
Fear • Fear can be learned through conditioning… • as well as through observation.
Don’t forget the Amygdala! • The neural key to fear learning. • Like a guard dog, it is continuously alert for threats.
Happiness People who are happy… • perceive the world as being safer. • make decisions easily. • are more cooperative. • live healthier, energized, and more satisfied lives.
However, Happiness Seems Not Much Related to Other Factors, Such as Age Gender (women are more often depressed, but also more often joyful) Education levels Parenthood (having children or not) Physical attractiveness Researchers Have Found That Happy People Tend to… Have high self-esteem Be optimistic, outgoing, and agreeable Have close friendships or a satisfying marriage Have work and leisure that engage their skills Have a meaningful religious faith Sleep well and exercise Predictors of Happiness

Values & Life Satisfaction Students who value love more than money report higher life satisfaction.
Adaptation-Level Phenomenon • Tendency to form judgments relative to a “neutral” level. • If you get a raise in salary, you feel good. But once you adjust to that new salary level, you need another raise to get that same feeling again. • Success and failure are always relative to our recent experiences.
Experiencing Emotion • Relative Deprivation: • Perception that one is worse off relative to those with whom one compares oneself.
