  • Wechsler's definition is the most comprehensive — it includes purposeful action, rational thinking, and effective environmental adaptation.
  • Intelligence can be viewed as a single factor (Binet, Spearman) or multiple factors (Thurstone, Guilford).

  • Cattell distinguished Fluid Intelligence (innate, declines with age) from Crystallized Intelligence (experience-based, stable or grows with age).

  • Information Processing Approach: Treats mind as a computer; intelligence is a process of analyzing environmental information.

  • Sternberg's Triarchic Theory: Three forms — Componential/Analytic, Experiential/Creative, and Contextual/Practical intelligence.
