Since the first mental age tests were administered in 1904, there have been several versions of intelligence tests. The most widely used test today is the Wechsler Intelligence Scale.
Why did David Wechsler design the Wechsler Intelligence Scale?
He didn’t feel that the other tests adequately measured intelligence levels in adults.
He felt that knowing someone’s mental age was important.
He needed a formula for comparing mental age to chronological age.
He wanted to know how someone was going to do in school.
David Wechsler designed the Wechsler Intelligence Scale because he didn’t feel that the other tests adequately measured intelligence levels in adults.
Explanation: The earlier intelligence tests, such as those developed by Alfred Binet, were primarily designed for children and focused on mental age. Wechsler believed that intelligence in adults required a different approach, as it encompasses a broader range of cognitive abilities, so he created a scale that assesses various aspects of intelligence without relying solely on mental age comparisons.
