Emotions — Psychology STD 12 Commerce / Arts — Question

Robert Plutchik presented the wheel of emotions,

1. there are 8 basic emotions viz. joy, trust, fear, surprise, sadness, anticipation, anger and disgust.
2. each primary emotion has its polar opposite such as fear is opposite of anger.
3. primary emotions combine to produce complex emotions, for e.g., love (complex) is a combination of joy and trust.
4. intensity of emotions increases as we move toward the centre and decreases as we move outward. For e.g., apprehension (weak) → fear (basic) → terror (strongest).

This model is important from the perspective of emotional literacy, i.e., understanding emotional levels, complexity and change as well as appropriate emotional labelling
