The test that includes Verbal Comprehension Index, Visual Spatial Index, Fluid Reasoning Index, Working Memory Index, and Processing Speed Index calculates what?

• A. Full Scale IQ
• B. General Ability Score
• C. Processing Index
• D. Verbal IQ

Answer: (A)

A full-scale IQ is the overall measure of general intellectual ability that this test provides by combining all five index scores. Each index—Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed—captures a different facet of cognition, from verbal knowledge and reasoning to nonverbal problem solving, memory, and how quickly someone can process information. When these areas are integrated, the resulting Full Scale IQ reflects overall intellectual functioning more accurately than any single domain could.

So, the best choice is the one that represents this global score. The other options point to narrower constructs: Verbal IQ would focus only on verbal abilities, while a Processing Index is not the overall measure, and a General Ability Score isn’t the standard name for this instrument’s composite.
