Which indices are used to calculate the FSIQ in WISC-V according to the material?

• A. Vocabulary, Block Design, Matrix Reason, Digit Span, Coding, Similarities, Figure Weights
• B. Verbal Comprehension, Visual Spatial, Working Memory, Processing Speed
• C. Vocabulary, Block Design, Matrix Reason, Digit Span, Coding
• D. Similarities, Comprehension, Picture Completion, Block Design

Answer: (A)

The main concept is that the Full Scale IQ on the WISC-V is built from five primary index scores: Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed. Each index is derived from a set of subtests, so the way the FSIQ is formed reflects performance across multiple cognitive domains rather than just one area. For example, Vocabulary and Similarities feed Verbal Comprehension; Block Design feeds Visual Spatial; Matrix Reasoning and Figure Weights feed Fluid Reasoning; Digit Span feeds Working Memory; and Coding feeds Processing Speed. The option that lists subtests spanning across these five domains shows how subtest data feed into the indices and, in turn, into the FSIQ. Other options either cover only a subset of indices or list subtests that don’t together map across all five domains, so they don’t align with how the FSIQ is calculated.
