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).
