Gregorio Marafion's Two-Factor Theory of Emotion
Gregorio Maranion's early studies of the psychological effects of adrenaline are described, along with his attempts to construct a model for the experience of emotion from the results of those studies. It is argued that Maranion's model anticipated in important ways Schachter's two-factor, or arousal-cognition, theory of emotion and that Maranion should be recognized as a pioneer in the development of cognitive theories of emotion.
