Basic emotion theory is a psychological framework that holds that a small number of emotions are universal, biologically based, and evolutionarily conserved. Proponents contend that these basic emotions are discrete states with distinct neural circuits, physiological patterns, and expressive behaviors, and that they emerge early in life across different cultures.

A commonly cited list includes happiness, sadness, fear, anger, disgust, and surprise, with some scholars adding contempt or other states. The idea is that each basic emotion has characteristic facial expressions and autonomic responses that reliably signal the internal state to others. This has been used to explain cross-cultural recognition of facial expressions and the adaptiveness of quick, affective responses to environmental challenges.

Evidence cited for basic emotions includes studies of facial emotion recognition across diverse populations, infant emotional behaviors, and neuroanatomical findings suggesting dedicated affective circuits. Critics, however, argue that emotions are more fluid and context-dependent than the model allows. Cultural display rules, individual learning, and situational appraisal can shape how emotions are felt and expressed. Some researchers advocate dimensional or constructivist approaches, viewing emotions as blends along continuous axes such as valence and arousal rather than as discrete units.

In practice, the concept has influenced affective science, social psychology, and affective computing, where researchers attempt to model and recognize emotional states. While influential, basic emotion theory remains debated, with ongoing discussion about how many basic emotions exist, what counts as “basic,” and how universally they are expressed.
