Intelligence in NCERT: From Binet to Gardner — All Theories Explained

Chapter 1 of Class 11 and parts of Class 12 cover intelligence theories extensively. Let's break them all down.

• *g* (general intelligence) + *s* (specific abilities)
• All intellectual activities share a common *g* factor

• 7 distinct abilities: Verbal, Word fluency, Number, Space, Memory, Perceptual speed, Reasoning

• 3D model: Operations × Contents × Products = 180 factors

• Fluid (Gf): Problem-solving with new info — peaks in youth
• Crystallised (Gc): Accumulated knowledge — grows with age

• Linguistic, Logical-mathematical, Spatial, Musical, Bodily-kinesthetic, Interpersonal, Intrapersonal, Naturalist

• Componential (analytical), Experiential (creative), Contextual (practical)

Board Tip: Gardner and Sternberg appear almost every year. Memorise their sub-types with one example each.
