There is nothing on this page which is not publicly available information but we do not recommend that you attempt to familiarize your child with the content of the WISC using the information on this page or other sources. Part of the WISC test protocol is to see how children will do when presented with questions of a type they haven't seen before. Composite scores relating to specific cognitive areas may also be reported (index scores can be produced in the areas of Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed.) In addition to subtest scores a combined composite score is reported (the IQ). There are 15 subtests on the WISC-IV but they may not all be used. You can read more about the WISC-IV here. Older children and adults are tested using the Wechsler Adult Intelligence Scale (WAIS). Younger children are tested using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). The symbol search subtest on the processing speed index asks test takers to quickly scan for certain images.įor all official Wechsler materials, visits Pearson Clinical.The Wechsler Intelligence Scale for Children (WISC-IV) is an individually administered IQ test used with children aged from 6 to 16. In this vein, the digit span subtest asks test takers to repeat a series of numbers backwards after hearing the prompt forwards. The working memory index tests your ability to keep many ideas in your mind at once. Working Memory and Processing Speed Indices In essence, the test taker needs to make up his own algorithm and find the pattern that connects all of the options. This subtest heavily taps into visual processing and inductive reasoning. On the WAIS' matrix reasoning subtest, test takers are asked to fill in the next bubble based on the preceding pattern of four images. The matrix reasoning subtest, alternatively, is perhaps the mental image of a typical IQ question in most people's minds. This tests abstract reasoning, visual processing and fine motor control. Having said all that, what are some typical questions on perceptual reasoning index subtests like block design and matrix reasoning? In essence, the block design subtest asks the test taker to replicate a two-dimensional design from a book in three dimensions using blocks. Most importantly, the perceptual reasoning index gauges the test taker's on-the-spot abstract reasoning ability whereas the verbal comprehension index chiefly tests the test taker on his or her acquired knowledge and rote memorization of facts. The perceptual reasoning index differs from the verbal comprehension index in some very critical ways. Example Questions on Perceptual Reasoning Index This would garner the full two points whereas a less focused answer ("they're both food") might receive one point. Of course, the correct answer is that both are fruits. For example, a test taker might be asked to say what the words "apple" and "orange" have in common. This subtest asks the test taker to articulate the correlation between two words or concepts. The verbal comprehension index on the WAIS also includes a subtest called Similarities. For instance, a test taker might be asked to define the word "articulate." The proctor asks the test taker to define a word and depending on his or her nuanced knowledge s/he receives a score from zero to two. The vocabulary test is fairly straightforward. So, what are some typical questions on the WAIS? On the verbal comprehension index, test takers will be tested on vocabulary measures as well as abstract reasoning ability. These four indexes are combined, weighted and averaged to derive the full scale IQ score on the WAIS. The new WAIS includes four index scores: verbal comprehension index, working memory index, perceptual reasoning index, and the processing speed index. These core subtests help to home in on the test taker's intelligence quotient. The WAIS is on its fourth edition and is comprised of 10 core subtests. The Wechsler Adult Intelligence Scale (WAIS) is intended for adolescents (16 and over) and adults.
