What else can be calculated from the 10 WAIS subtests other than FSIQ?

• A. Verbal comprehension
• B. Verbal comprehension, perceptual reasoning, working memory and processing speed index scores
• C. General Ability Index
• D. Processing speed score only

Answer: (B)

The key idea is that the WAIS provides more than a single overall score by organizing performance into specific cognitive domains. In addition to the Full Scale IQ, you can compute four index scores that summarize how a person performs in major areas: Verbal Comprehension, Perceptual Reasoning, Working Memory, and Processing Speed. Verbal Comprehension reflects verbal reasoning and understanding, drawing on subtests that measure verbal knowledge and concept formation. Perceptual Reasoning captures nonverbal problem solving and visuospatial processing. Working Memory assesses the ability to hold and manipulate information in mind, and Processing Speed looks at how quickly and accurately simple tasks can be completed. These indices come from subsets of the ten subtests, giving a detailed profile of strengths and weaknesses across different cognitive systems beyond the overall IQ. The other options don’t fit as completely: one omits three of the four indices, another points to a separate composite (General Ability Index) that is not the same as the standard index scores, and focusing on processing speed alone misses the broader, four-index picture.
