The primary purpose of this study was to investigate the various neurocognitive processes concomitant to reading by attempting to identify various subtypes of reading disorders in a referred sample. Participants were 216 elementary school students in grades two through five who were given select subtests of the Woodcock Johnson-III Tests of Cognitive Ability. They were classified using a pattern of strengths and weaknesses (PSW) approach as having no SLD (control), 49 had an Associative Learning (Glr) SLD, 21 had a Gf-Gv SLD, 42 had a Gc SLD, 29 had a Learning Efficiency (Gs) SLD, and 40 had an Executive (Gsm) subtype SLD. Regressions completed for each of the six groups indicated that differing sets of cognitive skills were predictive of reading performance pertaining to letter and word identification skills, reading fluency skills, and passage comprehension skills
