Includes verbal comprehensive index, visual spatial index, fluid reasoning index, working memory index, and processing speed index; used to calculate FSIQ.

• A. WAIS
• B. WISC
• C. WPPSI
• D. Stanford-Binet

Answer: (B)

The key idea is that Full Scale IQ on the Wechsler scales is calculated from five index scores: Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed. This exact five-index structure is characteristic of the Wechsler Intelligence Scale for Children, which is designed for kids and uses those indices to derive the FSIQ. The adult version (WAIS) uses a slightly different set of indices, and the preschool version (WPPSI) has its own structure for younger children. The Stanford-Binet uses a different factor model. So the choice that fits these five specific indices used to compute FSIQ is the Wechsler Intelligence Scale for Children.
