An abbreviated four-subtest version of the WAIS-III (called the Wechsler Abbreviated Scale of Intelligence (WASI)) has been released enabling clinicians to perform a validated verbal, performance and full-scale IQ in approximately 30 minutes.
Some clinicians use the WAIS with psychiatric illness or brain injury in order to assess impediments in cognitive reasoning, but use of the WAIS in this connection is controversial. The WAIS is also used as an instrument on a neurologically impaired population in order to link regions of the brain to specific variables of reasoning, as well as to gauge regions and extent of affected neural matter (the digit span, for instance, may be used to test attention and/or memory). Oftentimes, however, the WAIS-R NI (Wechsler Adult Intelligence Scale-Revised) is a preferred neuropsychological instrument. The WAIS was developed for average, brain-healthy individuals, and separate norms, patterned on the WAIS, are being developed for lesser cognitive functioning or brain damaged individuals.
Since I intend to go into education, I see knowledge of the Wechsler Scale as essential for my field, particularly...
Understanding the way it works would be helpful to my understanding the limits and advantages in using it to measure intelligence and how I need to integrate it with other measures and methods.

WAIS-IV Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV) The Wechsler Adult Intelligence Scale - Fourth Edition (WAIS-IV, Pearson Assessments, 2012) was designed to evaluate cognitive functioning in adults aged 16 to 90. The WAIS-IV is the most recent updated version (released in 2008) of the most commonly administered intelligence test for adolescents and adults (Canivez, 2010). The test has its roots in the Wechsler -- Bellevue Intelligence Scale (Wechsler, 1939). David
Explain the Global Ability Index and when to use it The alternative global score, the General Ability Index (GAI) is calculated when the test-taker "meets certain criteria that involve variability with respect to the cognitive factors of working memory and processing speed" (Cheramie 2008). For example, learning-disabled children often have lower levels of processing speed, thus the GAI is an acceptable scoring alternative to the usual method which does take memory

While it is almost certain that intelligence ahs a neurological basis, the extent to which intelligence is determined by neurological and chemical changes is not fully understood. A recent study suggests that changing hormone levels prior to and during puberty have a large effect on intelligence; high salivary testosterone levels in ten-year-old boys showed a positive correlation with intelligence, but a negative correlation in twelve-year-olds (Shangguan & Shi 2009).
Client Performance on Wechsler Adult Intelligence Scale (WAIS-III) The Full Scale Intelligence Quotient (FSIQ) for this client is 102, a score that is considered to be in the Average range. The Verbal IQ (VIQ) is 111 and the Performance IQ (PIQ) is 90. The client's 21-point score difference between the VIQ and the PIQ is significant, which means that the full-scale IQ score does not represent the client's abilities as
Wechsler Memory Scale-Third Edition (WMS-III) This is a paper that reports and critiques the Wechsler Memory Scale-Third Edition (WMS-III). It has sources in APA format. Standardized testing has become a norm for structuring studies on human behaviors. Studies on cognitive abilities, performance, behavior pattern as well as memory testing all have a great deal of dependence on the choice of the kind of tests adopted and the validity of the test is
