Which statement about a fixed battery in neuropsychology is true?

• A. It is a predefined set of tests defined within a framework and administered as a unit
• B. Tests are always chosen individually for each patient
• C. It excludes any standardized tests
• D. It is typically used only in experimental research

Answer: (A)

A fixed battery means a predefined, standardized set of tests that are chosen within a guiding framework and given together as a single package. This approach ensures consistency across patients and settings, allows clinicians to compare results using established norms, and provides a clear interpretation route based on how the entire set was designed to assess multiple cognitive domains. That’s why the statement describing a predefined set of tests administered as a unit best captures the essence of a fixed battery.

In contrast, the idea that tests are always chosen individually for each patient conflicts with the fixed-battery concept, because fixed batteries standardize test selection rather than tailoring every item to the individual. Saying it excludes standardized tests is incorrect, since fixed batteries rely on standardized, well-validated measures. And claiming it’s used only in experimental research ignores its widespread clinical use, where fixed batteries are common tools for comprehensive neuropsychological evaluation.
