Wechsler’s intelligence tests (e.g., WAIS, WISC) introduced separate scores for verbal and performance tasks. This contrasts with the Stanford-Binet test, which traditionally provided a single IQ score based on a ratio formula.
Wechsler’s approach allowed for a more nuanced understanding of cognitive strengths and weaknesses across different domains.
