The Elements of Emotional Experience
Cognitive component Subjective conscious experience Positive psychology Physiological component Bodily (autonomic) arousal Behavioral component Characteristic overt expressions
26
Opponent Process Theory of Emotion
Have you ever felt crappy for a few days, then felt elated? This theory says feeling one way will lead you to feel the opposite. How is this similar to the opponent process theory of color vision?

Culture and the Elements of Emotion
Cross-cultural similarities found in cognitive and physiological elements of emotional experience Also many cultural disparities in how people perceive, think about, and express their emotions socially engaging emotions socially disengaging emotions

30
Theories of Emotion James-Lange Cannon-Bard
Feel afraid because pulse is racing Cannon-Bard Thalamus sends signals simultaneously to the cortex and the autonomic nervous system
31
Theories of Emotion Schacter’s Two-Factor Theory Evolutionary Theories
Look to external cues to decide what to feel Evolutionary Theories Innate reactions with little cognitive interpretation

Happiness Common sense notions incorrect
Income, age, parenthood, intelligence, and attractiveness largely uncorrelated Physical health, good social relationships, religious faith, and culture modestly correlated Love, marriage, work satisfaction, and personality strongly correlated
35
Subjective Well-Being
Objective realities not as important as subjective feelings When it comes to happiness everything is relative People are surprisingly bad at predicting what will make them happy People often adapt to their circumstances Hedonic adaptation
