On Rearranging Picture Arrangement: Data from a Clinical Sample

Comparisons of the Wechsler Adult Intelligence Scale (WAIS) and the Wechsler Adult Intelligence Scale—Revised (WAIS—R) indicate that the two tests are highly similar but not identical. The present study examined the p-values of the WAIS—R Picture Arrangement items for a sample of 123 adults referred for psychological assessment. The current order of the Picture Arrangement items (especially the FLIRT item) does not conform to the expectation of increasing difficulty of subtest items. Implications for diagnosis are discussed.
