Emotions are complex psychological states that involve three distinct components: a subjective conscious experience (cognitive appraisal), a physiological response (autonomic arousal), and a behavioral or expressive reaction (facial expressions, posture). In the taxonomy of affective states, understanding the Types of Emotion is central to both experimental research and clinical diagnostics.
- Primary vs. Secondary Emotions: Pioneered by evolutionary perspectives (Darwin, 1872; Plutchik, 1980; Ekman, 1992), Primary (Basic) Emotions are universal, hardwired, and universally recognized across human cultures, consisting of anger, fear, sadness, disgust, joy, and surprise. Secondary (Complex) Emotions—such as guilt, shame, pride, jealousy, and empathy—are culturally mediated, develop later in ontogeny, and require higher-order cognitive appraisals and self-awareness.
- Plutchik's Psychoevolutionary Theory of Emotion: Robert Plutchik (1980) proposed a cone-shaped structural model featuring eight primary emotions arranged in opposing pairs: joy-sadness, anger-fear, trust-disgust, and anticipation-surprise. These combine to form secondary and tertiary emotions (dyads) and vary in intensity (e.g., ecstasy vs. serenity).
- Dimensional Models of Emotion: Moving beyond discrete categories, dimensional models (Russell’s Circumplex Model, 1980; Watson & Tellegen’s Positive and Negative Affect Schedule - PANAS) map emotions onto continuous axes of Valence (pleasantness/unpleasantness) and Arousal (activation/energy).
