WISC Subtest Scores of Disabled Readers:

Twenty-five studies which reported WISC subtest scores of disabled readers were reviewed. The subtests were reclassified into categories labeled Spatial, Conceptual, and Sequential, and disabled readers were ranked as to their relative strength in these three categories. Disabled readers were highest in the Spatial category, intermediate in the Conceptual category, and lowest in the Sequential category. The high rank in the Spatial category suggests that disabled readers are strong in visual-spatial skills. The low rank in the Sequential category can be accounted for by deficits in short-term memory processes and attentional processes.
