His fresh color and sandy hair and quick-changing blue eyes are those of a young man, and his sympathetic, solicitous interest in women is as youthful as it is Western and American.
The Wechsler Intelligence Scale for Children (WISC), developed by David Wechsler, is an individually administered intelligence test for children between the ages of 6 and 16. The Fifth Edition (WISC-V; Wechsler, 2014) is the most current version.
You'll recall the development of adult intelligence tests from earlier in the semester I hope. Basically, the WISC came out in 1949 as a downward extension of an adult IQ test, the Wechsler Bellevue, and was revised in 1974 (WISC R) by Wechsler. The Psychological Corporation revised it again in 1991 (WISC III), and again in 2003 (WISC IV).
