What are the three Wechsler intelligence tests?
The Wechsler scales include three individually administered scales of intelligence: Wechsler Preschool and Primary Scale of Intelligence-Revised (WIPPSI-R; Wechsler, 1989), Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991), and Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler.
What is Wechsler known for?
Wechsler is best known for his intelligence tests. He was one of the most influential advocates of the role of nonintellective factors in testing. He emphasized that factors other than intellectual ability are involved in intelligent behavior. Wechsler objected to the single score offered by the 1937 Binet scale.
Why did Wechsler develop his intelligence test?
The goal of his original test was to help identify children who needed specialized help in school and he felt that a variety of individual factors, including a child’s level of motivation, could influence test scores. In a sense, Wechsler’s test was a return to many of the ideas that Binet had also espoused.

How accurate is the Wechsler test?
Reliability and Validity The Wechsler Adult Intelligence is a well-established scale and it has fairly high consistency. Over a two to twelve week time period, the test-retest reliabilities ranged from 0.70 (7 subscales) to 0.90 (2 subscales).
Why are the Wechsler tests important?
Although there are many different reasons why the WAIS might be used, it’s sometimes used by neuropsychologists and rehabilitation psychologists in people who have been injured. They are able to utilize the test to see what areas of the brain have been affected as well as determine cognitive function.
Why are Wechsler tests still used today?
They are most useful in determining children who may need special attention, either because of disability or because of giftedness. Parents should consider the possible consequences carefully if they are considering telling their child the outcome of this or any other intelligence test.
What is the WISC test used for?
The WISC-IV measures intellectual ability of children from 6 to 16 years. It was developed to provide an overall measure of general cognitive ability, and also measures of intellectual functioning in Verbal Comprehension (VC), Perceptual Reasoning (PR), Working Memory (WM) and Processing Speed (PS).
