Q. Explain any three type theories of personality. (10 marks)
Also: "Discuss Sheldon's somatotype personality and Ayurvedic body types in Ayurvedic medicine." (2021-Dec B8); "What are Ayurvedic Body Types? Explain." (2013-Jun)
Introduction
Type theories of personality propose that people can be categorised into discrete, qualitatively distinct categories — types — based on shared patterns of behaviour, physique, or temperament. Unlike trait theories which place individuals on continuous dimensions, type theories assign individuals to categories. The oldest psychological typologies linked body constitution to character.
1. Hippocrates' Four Humours Theory (Historical)
Hippocrates (460–370 BC) proposed that personality is determined by the balance of four bodily humours (fluids):
- Blood → Sanguine temperament: cheerful, optimistic, sociable
- Yellow bile → Choleric: irritable, aggressive, ambitious
- Black bile → Melancholic: sad, anxious, thoughtful
- Phlegm → Phlegmatic: calm, reliable, unemotional
Though prescientific, this system introduced the idea that biology underlies personality and remained influential for 2,000 years.
2. Sheldon's Somatotype Theory
William Sheldon (1898–1977) developed a constitutional theory linking body build (somatotype) to temperament. He identified three primary body components:
| Somatotype | Physical Description | Temperament (Personality) |
|---|---|---|
| Endomorphy | Soft, round, fat body; prominent abdomen | Viscerotonia: relaxed, sociable, food-loving, comfort-seeking, affectionate |
| Mesomorphy | Muscular, hard, rectangular body; upright posture | Somatotonia: assertive, active, energetic, risk-taking, competitive |
| Ectomorphy | Thin, fragile, linear body; large brain relative to body | Cerebrotonia: restrained, introverted, self-conscious, inhibited, mentally intense |
Sheldon rated individuals on a 7-point scale for each component (e.g., 1-7-1 = extreme mesomorph). He reported correlations of ~0.80 between somatotype and temperament in his studies.
Criticism: Subsequent research found much lower correlations. Sheldon himself rated both physique and temperament, introducing bias. The theory is largely discredited in contemporary psychology but retains historical significance.
3. Ayurvedic Body Types (Doshas)
The Indian system of Ayurvedic medicine describes three biological energies (doshas) that govern body constitution and personality:
| Dosha | Element | Physical Characteristics | Personality |
|---|---|---|---|
| Vata | Air + Space | Thin, light, dry skin, irregular appetite | Creative, lively, variable mood, anxious when imbalanced |
| Pitta | Fire + Water | Medium build, sharp features, warm skin | Intelligent, focused, passionate, irritable when imbalanced |
| Kapha | Earth + Water | Heavy, solid build, oily skin, slow metabolism | Calm, loving, stable, lethargic when imbalanced |
Most individuals have a dominant dosha with secondary influences. Ayurvedic personality assessment is integrative, linking body, mind, and spirit — an early biopsychosocial model.
Conclusion
Type theories, though often criticised for oversimplifying the complexity of personality into discrete categories, represent early attempts to link biology with behaviour. Modern trait theories (Big Five, Eysenck's PEN) have largely replaced them, but their insight that biology shapes temperament is validated by contemporary behavioural genetics.
📝 Section B Answer (250 words / 6 marks)
Q. Discuss Sheldon's somatotype personality and Ayurvedic body types in Ayurvedic medicine. (6 marks)
Use the tables from the master answer. Cover Sheldon's three somatotypes with their temperaments (3–4 sentences) + the three Ayurvedic doshas with personality profiles (3–4 sentences). ~250 words.
🧠 Memory Aid
Sheldon's types: "EME" — Endomorph (soft/social), Mesomorph (muscular/active), Ectomorph (thin/introverted)
Ayurvedic doshas: "VPK" — Vata (air/creative), Pitta (fire/intelligent), Kapha (earth/calm)
💡 Exam Tips
- When asked for "three type theories," choose: Hippocrates + Sheldon + Ayurvedic — this covers historical, Western scientific, and Eastern perspectives.
- The table format for Sheldon and Ayurvedic types maximises marks for minimal words.
- Always note Sheldon's criticism (methodological bias) — shows critical awareness.
