Emotion theory

The four most common emotions on theorists' lists, and the basic states of Commedia dell'arte, are fear (or terror, shock, surprise), anger (or rage), sorrow[?] (or sadness), and joy (happiness, glee).

Robert Plutchik[?] developed his psychoevolutionary theory of basic emotions in 1980, with ten postulates, and eight basic emotions: fear, anger, sorrow, joy, and disgust, acceptance[?], anticipation[?], and surprise. Inclusion is based on relevance to adaptive biological processes (i.e. evolution).
