In the context of intelligence tests, which of the following is true about the Wechsler Adult intelligence Scale-IV(WAIS-IV)?

A-It’s the least frequently used IQ test in the United States
B-It requires individualized, one-on-one administration
C-It’s also known as the Stanford-Binet Intelligence Scale because of its reliance on Alfred Binet’s approach
D-It’s performance part consists of traditional kinds of problems such as vocabulary definition

B-It requires individualized, one-on-one administration

The correct answer is:

B- It requires individualized, one-on-one administration

The Wechsler Adult Intelligence Scale-IV (WAIS-IV) is a widely used IQ test in the United States. It is administered on an individual basis, with a trained examiner conducting the test in a one-on-one setting. The test measures various cognitive abilities, including verbal comprehension, perceptual reasoning, working memory, and processing speed. The performance part of the test does not consist of traditional kinds of problems like vocabulary definition.

To determine which statement is true about the Wechsler Adult Intelligence Scale-IV (WAIS-IV), we need to examine each option:

A- The statement that the WAIS-IV is the least frequently used IQ test in the United States is not accurate. In fact, the WAIS-IV is one of the most widely used intelligence tests in the United States, and it is recognized as a reliable and valid measure of cognitive ability.

B- The statement that the WAIS-IV requires individualized, one-on-one administration is accurate. The WAIS-IV is designed to be administered on an individual basis by a trained examiner. This allows for personalized interaction with the test-taker and ensures that the test administration is standardized and consistent.

C- The statement that the WAIS-IV is also known as the Stanford-Binet Intelligence Scale due to its reliance on Alfred Binet's approach is not correct. The WAIS-IV is a separate intelligence test developed by David Wechsler and is not directly related to the Stanford-Binet Intelligence Scale, which is a different test created by Alfred Binet and Theodore Simon.

D- The statement that the performance part of the WAIS-IV consists of traditional kinds of problems, such as vocabulary definition, is not accurate. The WAIS-IV includes various subtests that assess different cognitive abilities, and it does not solely focus on traditional problem-solving tasks like vocabulary definition. It measures different aspects of intelligence, including working memory, processing speed, verbal comprehension, and perceptual reasoning.

In summary, option B is the correct statement about the WAIS-IV - it requires individualized, one-on-one administration.
