Question

Which theory of intelligence was propounded by Charles Spearman?

• A. Two-factor theory
• B. Group-factor theory
• C. Multi-factor theory
• D. Unifactor theory

Hint:

Spearman = \(g + s\) (Two-factor). Thurstone = Primary Mental Abilities (group/multifactor flavor).

Answer 1

The Correct Option is A

Spearman proposed the Two-factor model: a general factor \(g\) common to all intellectual tasks and specific factors \(s\) unique to particular tasks. Group-factor and multifactor approaches belong to Thurstone and others.
