(a) During Word reading only, word reading ability, as measured by Word Attack (green) and Letter Word Identification (red) measures, predicts activation in language regions, including the orthographic processing regions in the left OT area. Both measurements of word reading predicted activation in the left MTG (yellow). (b) Plot of LWID Percentile score by Words percet signal change in the left OT area. Low and high word reading ability (as determined by median split of LWID percentile) represented in dark blue and light blue, respectively. Results displayed at p-corrected <.05 (p.unc <.005, k=118).
