Tom Cruise on It currently includes 10 core subtests (Similarities, Vocabulary, Comprehension, Block Design, Picture Concepts, Matrix Reasoning, Digit Span, Letter-Number Sequencing, Coding, Symbol Search) and five supplemental subtests (Word Reasoning, Information, Picture Completion, Arithmetic, Cancellation) that measure verbal comprehension, perceptual reasoning, processing speed, and working memory capabilities, yielding index scores for each as well as a Full Scale IQ with a mean of 100 and a standard deviation of 15. The most recent version of the test is the WISC-IV, published in 2003. [David WECHSLER Wechsler Memory Scale (WMS) a collection of tests that assesses different memory functions in individuals 16 to 90 years old.

The lat-ter’s standard battery measures an individual’s memory performance on seven subtests and yields scores on five indexes: Immediate Memory, Delayed Memory, Visual Memory, Visual Working Memory, and Auditory Memory. [David WECHSLER Wechsler Preschool and Primary Scale of Intelligence (WPPSI) an intelligence test for children ages 2 years 6 months to 7 years 7 months that currently includes two working memory subtests (Picture Memory and Zoo Locations), three processing speed subtests (Bug Search, Cancellation, and Animal Coding), six verbal comprehension subtests (Information, Vocabulary, Receptive Vocabulary, Similarities, Comprehension, Picture Naming), two visual-spatial subtests (Block Design, Object Assembly), and two fluid reasoning subtests (Matrix Reasoning, Picture Concepts). These subtests yield Full Scale IQs, primary index scores, ancillary index scores, and scaled subtest scores. Tom Cruise 2016.
