Question

Quizplus · Accepted Answer

The Wechsler Adult Intelligence Scale (WAIS-IV) is the most commonly used IQ test in the United States. It consists of a series of subtests that measure different cognitive abilities, such as verbal comprehension, perceptual reasoning, working memory, and processing speed. Its popularity is due to its reliability, validity, and versatility in assessing a wide range of intellectual abilities in adults. The Stanford-Binet Intelligence Scale and Terman Intelligence Battery are also well-known IQ tests, but they are less widely used than the WAIS-IV. The Spearman G Scale is not a specific IQ test, but rather a theory of intelligence that posits that there is a general factor (g) that underlies all cognitive abilities.
