WAIS Performance Subtests: Historical Overview

Historical context: The list below preserves the terminology used on the original FreeIQTest.info page. “Performance subtests” describes older Wechsler editions; current editions use updated subtests and index structures. FreeIQTest.info is an independent IQ-style quiz, not an official WAIS assessment.

WAIS IQ Test | Picture Completion - Perceiving visual details (e.g., recognizing similarities and differences between figures)

WAIS IQ Test | Digit Symbol — Coding - Visual-motor coordination, motor and mental speed

WAIS IQ Test | Block Design - Spatial perception, visual abstract processing & problem solving

WAIS IQ Test | Matrix Reasoning - Nonverbal abstract problem solving, inductive reasoning, spatial reasoning

WAIS IQ Test | Picture Arrangement - Logical/sequential reasoning, social insight

WAIS IQ Test | Symbol Search - Visual perception, speed

WAIS IQ Test | Object Assembly - Visual analysis, synthesis, and construction

These names are useful when reading the history of intelligence testing, but they should not be treated as a current WAIS-5 subtest list.
