David Wechsler developed the Wechsler Intelligence Scale for Children. He created it to assess a child’s cognitive abilities with a balanced, multi-subtest approach, yielding a Full Scale IQ and separate index scores for different cognitive domains, incorporating both verbal and nonverbal tasks. The WISC first appeared in 1949 and has been revised several times, expanding on his earlier work with the adult WAIS. This distinguishes him from Alfred Binet, who devised the original Binet-Simon scale that inspired the Stanford-Binet; Lewis Terman, who revised it into the Stanford-Binet; and Jean Piaget, who is known for his theories of cognitive development rather than for creating an IQ test.
