The Wechsler Intelligence Scale is a widely used test designed to measure human intelligence. Developed by David Wechsler, it assesses various cognitive abilities through different subtests, including verbal comprehension, perceptual reasoning, working memory, and processing speed. The results provide an overall IQ score, which helps in understanding an individual's intellectual capabilities. There are several versions of the scale, including the Wechsler Adult Intelligence Scale (WAIS) for adults and the Wechsler Intelligence Scale for Children (WISC) for children. These assessments are often used in educational, clinical, and research settings to identify learning disabilities, giftedness, and other cognitive profiles.
