Advanced Clinical Solutions for the WAIS®-IV and WMS®-IV (ACS) Object Assembly was also dropped for a variety of reasons. Ultimately, some difficult choices were made to make room for new subtests. It was lengthy to administer, the subtest manipulatives were heavy and contained multiple pieces that could be lost or damaged, or administered inconsistently. Picture Arrangement was dropped for a variety of reasons. The creation of new subtests was equally guided by clinical research and factorial data. The development of the WAIS-IV was significantly influenced by current research in neurocognitive information processing models. The additional information from the supplemental subtest can help tease out factors contributing to disparate results. Supplemental subtests are also useful when the scores within an index are widely discrepant. If you need to use a supplemental subtest in place of a core subtest for clinical reasons, decide this before you administer the subtest-not after you have derived scaled scores.įor example, an individual with motor impairment may be administered Figure Weights as a substitute for Block Design. However, you should decide before you administer the subtests which one to use to derive composite scores. Supplemental subtests are also used to provide additional information on cognitive functioning.
Can I give all the core and supplemental subtests and choose to use the highest subtest scaled scores when computing composite scores? When deriving composite scores, you can only substitute supplemental subtests substituted for core subtests that are spoiled or invalidated. However, you can only substitute a maximum of two subtests total to retain the validity of the FSIQ. Yes, you can substitute one supplemental subtest per index. You may also call Customer Support at Some WAIS-III subtests that demonstrated relatively lower reliability were dropped from the battery or no longer contribute to the composite scores. Contributes to Perceptual Reasoning Composite, measure of quantitative and analogical reasoning, requires no motor skills.

System gpu 0 copyĪ core battery of 10 unique subtests focuses on four specific domains of intelligence: verbal comprehension, perceptual reasoning, working memory, and processing speed. WAIS-IV was developed to provide the most advanced measure of cognitive ability and results when addressing the changing clinical landscape.
