The F-A-S test assesses which cognitive ability?

• A. Verbal fluency
• B. Visual memory
• C. Long-term memory
• D. Processing speed

Answer: (A)

Verbal fluency, specifically phonemic fluency, is what the F-A-S task measures. It asks you to generate as many words as possible that start with a given letter (F, A, S) within a fixed time. Performance reflects how quickly you can retrieve words from your mental lexicon and how effectively you search, switch strategies, and monitor for repetitions or rule violations. This taps language production and executive control more than memory for visuals or for past experiences. It’s not a test of visual memory or long-term memory, which involve different kinds of remembering, and while processing speed affects performance, the central skill being assessed is the rapid retrieval and articulation of phonemically constrained words—verbal fluency.
