The Wechsler intelligence test method is a commonly used, rather widely regarded assessment method throughout the world. He is a series of intelligence test scales prepared under the auspices of David Wechsler in the United States in 1955, and is currently the most widely used intelligence test scale in the world, consisting of three main sets, divided into human, child and toddler scales. The Wechsler Adult Intelligence Scale also includes 11 subscales, including the verbal scale, general knowledge, comprehension, arithmetic, similarity, multiples, vocabulary; there are five operational scales including fill-in-the-blank, blocks, diagrammatic arrangement, number symbols, piecing together, and mazes. The scoring principle is to give one point for correct answers and zero points for wrong answers, and the total score of the test is the speed of the questions passed, i.e. the raw score of the test.
