In standardization, examinees typically are administered both the main test being standardized (e.g., WAIS–IV) and various other tests required to establish validity (e.g., WMS–IV, WAIS–III). This is due to the difference in the core subtests between WAIS–III and WAIS–IV; core subtests in the WAIS–IV reflect the increased emphasis on fluid reasoning, working memory, and processing speed in more recent conceptualizations of intelligence. Compared to the WAIS–III, the WAIS–IV FSIQ deemphasizes crystallized knowledge (Comprehension is supplemental), and increases the contribution of Processing Speed (both Coding and Symbol Search are core). �� �/�W�1�`�f2`��0���I&c�R�n&+�����,��T�3s I��QK%�~“e��o��`�N�;��ýkpU�,+�AAD s��� See Appendix C of the WAIS–IV Technical and Interpretive Manual for the norms table and other pertinent analyses relevant to using the GAI.
