Raven in depth
Raven's Progressive Matrices — Nonverbal — minimal cultural or language bias; measures fluid reasoning directly. It's typically used for cross-cultural research, nonverbal assessment, fluid-intelligence measurement. Only tests fluid reasoning (one of several cognitive factors).
WISC in depth
Wechsler Intelligence Scale for Children — Widely used in schools and clinics for children. It's typically used for child cognitive assessment, giftedness identification, learning-difference evaluation. Adults need WAIS; requires trained examiner.
