Plutchik's Wheel of Emotions is a classic emotion model proposed by American psychologist Robert Plutchik in 1980. It is known as the "color wheel" or "map" of the emotional world. I. Core Structure: 3 Rules 1. 8 Basic Emotions (Primary Colors) The wheel is divided into 8 sectors, representing the most basic human emotions (paired opposites): - Joy ↔ Sadness - Anger ↔ Fear - Trust ↔ Disgust - Anticipation ↔ Surprise 2. Emotional Intensity (From Outside to Inside) - Outer Circle: Low intensity (e.g., annoyance, worry, calm) - Middle Circle: Medium intensity (basic emotions: anger, fear, joy) - Center: High intensity (e.g., rage, ecstasy, despair) 3. Complex Emotions (Mixed Colors) The mixing of two adjacent basic emotions produces more nuanced and complex emotions: - Joy + Trust = Love - Anticipation + Joy = Optimism - Fear + Surprise = Awe - Anger + Disgust = Contempt
