Are these as reliable as the WAIS–III VIQ and PIQ were? The VCI and the PRI are derived from three subtests. The WAIS–III subtests used to derive the FSIQ included only one subtest from the Processing Speed scale and one additional subtest each from the Verbal Comprehension and Perceptual Organization scales. The WAIS–IV FSIQ is composed of all 10 subtests that comprise the four index scores, including the Working Memory and Processing Speed subtests. How is the WAIS–IV FSIQ different than the WAIS–III FSIQ?Ĭompared to the WAIS–III, the WAIS–IV FSIQ de-emphasizes crystallized knowledge (Comprehension is supplemental), and emphasizes the contribution of Processing Speed (both Coding and Symbol Search are core).
