PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Wechsler Scales. The Wechsler scales measure intelligence from 2:6 to 90 years. The latest versions are the WPPSI-IV for preschool and primary-grade children, the WISC-V for elementary and high-school children, and the WAIS-IV for adolescents, adults and elders.

Detailed explanation-2: -The Wechsler Adult Intelligence Scale (WAIS) intelligence quotient (IQ) tests are the primary clinical instruments used to measure adult and adolescent intelligence. The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler-Bellevue Intelligence Scale.

Detailed explanation-3: -The Stanford-Binet test reflected mostly verbal abilities, while the Wechsler test also reflected nonverbal abilities. The Stanford-Binet has also been revised several times and is now similar to the Wechsler in several aspects, but the Wechsler continues to be the most popular test in the United States.
