It is possible that reading experience mediates the relationship between reading skill and cortical thickness. Print exposure, a measure of reading experience, accounts for variability in reading skill independently of phonological awareness and decoding skill (e.g. Stanovich & Cunningham, 1992). Several studies have found altered cortical structure in dyslexic readers throughout the posterior section of the reading network. Given the documented relationship between exposure to print and reading sub-skills, including phonological and orthographic processing, it is surprising that the relationship between exposure to print and cortical structure or function has not been explored. This study investigated the associations between cortical thickness in the left hemisphere reading network, reading skill, and print exposure in a sample of adult readers of varying reading skill. The pattern of correlations indicate that individuals with more print exposure, and who are of higher reading skill, had thicker cortices within the left hemisphere reading network.
