An examination of the relationship between reading comprehension, higher-level and lower-level reading sub-skills in adults

Abstract

Using a large adult reading database, we examined the relationships between high-level and low-level reading skills and between multiple reading skills, general cognitive ability, and reading comprehension ability. A principal components analysis found partial dissociability between higher-level skills including reading comprehension, vocabulary and print exposure, and lower-level skills including decoding and spelling in adult readers. Furthermore, follow-up regression analyses showed that the high-level sub-skills (e.g., vocabulary and print exposure) were significantly better predictors of reading comprehension ability than the low-level skills (e.g., decoding and spelling) in adult skilled readers. These findings suggest that higher-level and lower-level skills are dissociable in adult skilled readers and that higher-level skills are more strongly related to comprehension ability in adults.
