Document Summary
Emotions are essential elements for our humanity. Multidimensional scaling is a technique used to generate a map of emotional landscape. Valence is how positive or negative the experience is. Arousal is how active or passive the experience is. Emotion is a positive or negative experience that is associated with a particular pattern of psychological activity. Cannon-bard theory of emotion states that a stimulus simultaneously triggers activity in the autonomic nervous system and emotional experience in the brain. Undifferentiated physical arousal is the claim by schachter and singer that different emotions are different interpretations of a single pattern of bodily activity two-factor theory states that emotions are inferences about the causes of physiological arousal. Schachter and singer believed that people have the same physiological reaction to all emotional stimuli but they interpret that reaction differently on different occasions. Appraisal is an evaluation of the emotion-relevant aspects of a stimulus.
