Chapter 10: Emotions Two main components are involved in emotions: physiological arousal and subjective feeling. Cannon-Bard theory: physiological arousal and subjective feeling happen at the same time. James-Lange theory: the subjective feeling is the interpretation of the physiological arousal.     Peripheral feedback effect: changes in bodily states can produce changes in subjective feeling. Schachter and Singer’s two-factor theory: in response to increased arousal we search the environment to identify the cause of the arousal and thus infer how we should feel. Opponent-process theory: an emotional reaction to an event is often automatically followed by an opposite emotional reaction; additionally, repeated exposure to a stimulus causes the initial reaction to weaken and the opposite reaction to strengthen. Non-verbal communication: accounts for 60% to70% of all communication -> we cannot not communicate.     6 basic emotions are thought to be universally present on human faces: anger, disgust, fear, happiness, sadness, surprise.     Other non-verbals are more culture-specific.
