Today's question
Raven's Progressive Matrices were designed to measure which form of intelligence?
Reveal the answer and explanation
Correct: B — Fluid intelligence (novel reasoning)
Raven (1938) constructed the matrices specifically to measure Spearman's general factor "g" with minimal verbal or cultural load — pure pattern completion under novel constraints. The test has become the canonical fluid-intelligence instrument. Performance correlates strongly with working memory capacity and is a primary tool for studying the Flynn effect and the cognitive consequences of aging.
