What does cancellation measure on the WAIS-IV?

The lowest loading subtest in the WAIS-IV is Cancellation at 0.37, and it is construed as primarily a measure of processing speed. The Cancellation subtest should theoretically also constitute a good means of assessing visual field neglect.

How do you score a block design on WAIS?

The Block Design No Time Bonus (BDN) process score is calculated by awarding only four points for correctly completed items for which time-bonus points are possible. Calculate this score carefully, not awarding more than 4 points for any item.

Is the WAIS-IV valid?

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). Inter-scorer coefficients were very high, all being above 0.90.

How is the Wechsler test scored?

The Wechsler scales yield a standard score with a mean of 100 and a standard deviation of 15. The scale yields a standard score with a mean of 100 and a standard deviation of 16. As such, a cutoff score reflecting 2 standard deviation units below the mean is lower (IQ of 68) when compared with the Wechsler scales.

What does pair cancellation measure?

The WJ III Broad Attention cluster measures four different cognitive aspects of attention: The Numbers Reversed Test measures attentional capacity; The Auditory Working Memory test measures the ability to divide information in short-term memory; The Auditory Attention test measures the ability to attend to speech …

What does perceptual reasoning measure on the WAIS IV?

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

What do WAIS-IV subtests measure?

The subtest was developed to measure non-verbal reasoning and the ability to understand abstract visual information. The individual is presented with a picture of a pair of scales in which there are missing weights, and they have to choose the correct weights to keep the scales in balance.

What does a low block design score mean?

Low NSI scores may occur for many reasons, including visual-processing deficits, information retrieval difficulties, weak language skills, poor naming skills, or generally slow cognitive functioning.

Is the WAIS reliable?

The WAIS-III IQ and Index scores are consistently the most reliable scores, in terms of both internal consistency and test–retest reliability. The most internally consistent WAIS-III subtests are Vocabulary, Information, Digit Span, Matrix Reasoning, and Arithmetic.

How many subtests does WAIS-IV have?

10 core
The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests comprising the Full Scale IQ. With the new WAIS-IV, the verbal/performance subscales from previous versions were removed and replaced by the index scores.

What is a good WAIS score?

The Wechsler tests have long been regarded as the “gold standard” in IQ testing….Wechsler Intelligence Scales.

Corresponding IQ Range Classifications More value-neutral terms
120–129 Superior Well above average
110–119 High average High average
90–109 Average Average
80–89 Low average Low average

What is a good Wppsi score?

Average: 90-109. The vast majority of children tested will score in this range with a mean (averaged) score of 100; the highest possible score on the WPPSI-IV is 160. High Average: 110-119.

What are the IQ levels for WAIS IV?
