The WAIS-IV has excellent reliability. Subtest stability coefficients range from adequate (0.74) to excellent (0.90). Clinical Utility: Subtest stability coefficients range from adequate (0
To appreciate the WAIS IV, one must understand its origins. Early 20th-century intelligence tests (like the Stanford-Binet) focused heavily on verbal abilities and speed, often yielding a single, monolithic IQ score. Psychologist David Wechsler argued that intelligence was not a single entity but a composed of different abilities. or seizure disorder
