The PSI is a measure of processing speed. The 2014 publication of the WISC-V contained five ancillary index scores that may be derived for special clinical purposes or situations: the Quantitative Reasoning Index (QRI), the Auditory Working Memory Index (AWMI), the Nonverbal Index (NVI), the General Ability Index (GAI), and the Cognitive ...
There are four index scores representing major components of intelligence: [3] Verbal Comprehension Index (VCI) Perceptual Reasoning Index (PRI) Working Memory Index (WMI) Processing Speed Index (PSI) Two broad scores, which can be used to summarize general intellectual ability, can also be derived:
In addition, the Processing Speed Quotient (known as the Processing Speed Index on previous Wechsler scales) can be derived for children aged 4 – 7 years 3 months, and a General Language Composite can be determined for children in both age bands (2 years 6 months – 3 years 11 months & 4–7 years 3 months). Children in the 2 years 6 months ...
Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V) IQ classification IQ Range ("deviation IQ") IQ Classification [40] 130 and above Extremely High 120–129 Very High 110–119 High Average 90–109 Average 80–89 Low Average 70–79 Very Low 69 and below Extremely Low
The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
David "Weshy" Wechsler (/ ˈ w ɛ k s l ər /; January 12, 1896 – May 2, 1981) was a Romanian-American psychologist.He developed well-known intelligence scales, such as the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Intelligence Scale for Children (WISC) to get to know his patients at Bellevue Hospital.
[21] [22] The WCST, relies upon a number of cognitive functions including attention, working memory, and visual processing. [ 23 ] [ 24 ] [ 25 ] The WCST was originally developed to measure abstract reasoning [ 26 ] as such it may be used to help measure an individual's competence in abstract reasoning, and the ability to change problem-solving ...
The WIAT-III US was standardised on 3,000 students and adults aged 4–19:11. Linking studies were carried out with the WAIS-IV, WISC-IV, WPPSI-III, WNV, and DAS-II with correlations ranging from .60-.82. Special group studies include those with learning difficulties in reading, writing and math, expressive language disorder and mild ...
