The Wechsler Adult Intelligence Scale | Fourth Edition (WAIS-IV) is the most advanced adult measure of cognitive ability, based on recent research in the area of cognitive neuroscience and the theories and work of David Wechsler PhD.

The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. [1] For children between the ages of 6 and 16, Wechsler Intelligence Scale for Children (WISC) is commonly used.

The Wechsler Adult Intelligence Scale (WAIS) is one of the most extensively employed instruments for assessing adult cognitive functioning. Originally introduced by David Wechsler in 1955, the WAIS has undergone several revisions, culminating in its current version, the WAIS-IV, released in 2008.

WAIS is a comprehensive intelligence test for adults, diagnosing disabilities and guiding interventions. WAIS-IV evaluates verbal comprehension, reasoning, memory, and processing speed.

It measures nonverbal reasoning skills and taps into thinking that is more fluid and requires visual perceptual abilities. This index reflects an individual’s ability to take in and hold information in immediate awareness and then perform a mental operation on that information. It also measures the mental manipulation of number operations.
