Definitions for "WECHSLER"
David Wechsler (1896-1981), a Roumanian-born psychologist, was for many years chief psychologist at the Bellevue Psychiatric Hospital in New York and developed the Wechsler-Bellevue Intelligence Scale, which became the Wechsler Adult Intelligence Scale (WAIS), as well as various other scales. His first measures were introduced in 1939, and the Psychological Corporation continues to develop and build on his work. These are generally considered the best psychological measures in terms of reliability and validity and the most recent versions, including WAIS-III, have very extensive normative data available including UK data collected by teams of collaborators.
