289880464catharsisemotional release. In psychology, the catharsis hypothesis maintains that "releasing" aggressive energy (through action or fantasy) relieves aggressive urges.
289880465feel-good, do-good phenomenonpeople's tendency to be helpful when already in a good mood

289880471Cannon-Bard theorythe theory that an emotion-arousing stimulus simultaneously triggers (1) physiological responses and (2) the subjective experience of emotion
289880472two-factor theorySchachter's theory that to experience emotion one must (1) be physically aroused and (2) cognitively label the arousal
