Which test developed by Wechsler is the most frequently administered intelligence test for adults?

The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler–Bellevue Intelligence Scale, released in 1939. It is currently in its fourth edition (WAIS-IV) released in 2008 by Pearson, and is the most widely used IQ test, for both adults and older adolescents, in the world.

What is the difference between the Wechsler intelligence tests and the Binet intelligence test?

Stanford-Binet and Wechsler Adult Intelligence Scale (WAIS) IQs were compared for a group of 74 adults with intellectual disability (ID). In every case, WAIS Full Scale IQ was higher than the Stanford-Binet Composite IQ, with a mean difference of 16.7 points.

What does WISC-V figure weights measure?

Quantitative Reasoning Index
Figure Weights and Arithmetic comprise the Quantitative Reasoning Index (QRI), which measures quantitative reasoning skills. Quantitative reasoning is closely related to general intelligence and can indicate a child’s capacity to perform mental math operations and comprehend abstract relationships.

What is perceptual reasoning on the WISC-IV?

Perceptual Reasoning Index: A measure of an individual’s ability to understand visual information and to solve novel abstract visual problems.

Which test developed by Wechsler is the most frequently administered intelligence test for children?

The most commonly used test series is the Wechsler Adult Intelligence Scale (WAIS) and its counterpart, the Wechsler Intelligence Scale for Children (WISC). Other commonly used tests include the original and updated version of Stanford-Binet, and the Kaufman Assessment Battery for Children.

What does the Wechsler test measure?

The Wechsler Scales provide an estimate of global intellectual ability (Full Scale IQ) and four Composites: Verbal Comprehension Index (VCI), which measures the application of verbal skills and information to problem solving; Perceptual Reasoning Index (PRI), which measures the ability to engage in nonverbal reasoning …

What is different about the Wechsler intelligence tests than the Stanford Binet and other standardized IQ tests?

The Wechsler scales contained separate subscores for verbal IQ and performance IQ, and were thus less dependent on overall verbal ability than early versions of the Stanford-Binet scale.

What is wrong with WAIS-IV and WISC-IV?

Both studies suffer from a number of theoretical, methodological, and practical problems that significantly limit conclusions and recommendations for practitioner interpretations of these instruments. Additional analyses and research are required to better inform practitioners for WAIS-IV and WISC-IV use.

What is the difference between the WISC-IV and the WISC-V?

Short-term memory is also important for processing speed. The WISC-V dropped the Freedom from Distraction Index (FDI) which was scored in the WISC-IV. However, the essence of that variable is contained in the WMI index. The WISC-V Verbal Comprehension Index (VCI) is much the same as the WISC-IV Verbal Comprehension Index.

What is the Wechsler Intelligence Scale for Children (WISC)?

The original Wechsler Intelligence Scale for Children (WISC®), developed by David Wechsler, was developed in 1949 at Bellevue Hospital in New York City. It was an abbreviated adaptation of the original Wechsler-Bellevue Scale.

What is the PSI on the WISC-IV?

The Processing Speed Index (PSI), measuring how fast children are able to perform perceptual-motor tasks, is present in both the WISC-IV and the WISC-V. The Test Tutor is a team of test preparation experts.
