The Wechsler Adult Intelligence Scale (WAIS) is a widely used test designed to measure the intelligence of adults. Developed by David Wechsler, it assesses various cognitive abilities through different subtests, including verbal comprehension, perceptual reasoning, working memory, and processing speed. The WAIS provides a comprehensive evaluation of an individual's intellectual capabilities. The WAIS is often used in clinical, educational, and research settings to identify cognitive strengths and weaknesses. It helps psychologists and other professionals understand an individual's cognitive profile, which can inform decisions regarding education, employment, and mental health interventions.
