What does the Vocabulary subtest on the WAIS-IV measure?
As a direct assessment of word knowledge, the subtest is one indication of his overall verbal comprehension. Performance on this subtest also requires abilities to verbalize meaningful concepts as well as to retrieve information from long-term memory (Vocabulary scaled score = 12).
What does the Vocabulary subtest measure?
Vocabulary measures the students’ verbal fluency and concept formation, word knowledge, and word usage. Here’s one subtest in which prior knowledge does play a role. Matrix Reasoning measures visual processing and abstract, spatial perception and may be influenced by concentration, attention, and persistence.

Coding—the student matches and copies symbols that are associated with either objects (i.e., Coding A) or numbers (Coding B). This subtest is a measure of processing speed, short-term visual memory, mental flexibility, attention, and motivation.
What is perceptual reasoning?
Perceptual reasoning is the ability to take in visual information and organize it, interpret it, and use it to solve problems. No verbal communication is required. If you’re solving a problem that requires you to visualize the solution in your head, you’re using perceptual reasoning.
