Which assessment is primarily focused on measuring the cognitive aspects of behavior?

The Wechsler Adult Intelligence Scale (WAIS) is designed specifically to assess various cognitive abilities in adults. It provides a comprehensive evaluation of intelligence through several subtests that measure verbal comprehension, perceptual reasoning, working memory, and processing speed. By focusing on these cognitive aspects, the WAIS helps in understanding an individual's intellectual capabilities and is often used in both clinical and educational settings.

Other assessments, while useful for different purposes, do not primarily focus on cognitive aspects of behavior. The MMPI (Minnesota Multiphasic Personality Inventory) is more concerned with psychological conditions and personality traits rather than solely cognitive functions. The SASSI (Substance Abuse Subtle Screening Inventory) concentrates on identifying substance abuse disorders, and the DAST (Drug Abuse Screening Test) evaluates drug use behavior. Hence, the WAIS stands out as the tool that specifically targets cognitive assessment.
