Bottom‐up processing and reading comprehension in experienced adult readers

Previous research has indicated a weak to moderate role for word recognition skill in contributing to reading comprehension efficiency in highly experienced adult readers. The goal of this study was to re‐evaluate the strength of this association, including assessment of the contribution of skill in discriminating unfamiliar shapes and identifying letters. Unexpectedly, the results revealed a very strong association between efficiency in reading connected text and word recognition skill, as measured by efficiency of access to the orthographic lexicon. Ability to identify letters rapidly and accurately also contributed to orthographic access skill. These associations were only minimally reduced by controlling for skill in discriminating unfamiliar shapes. The results were interpreted in terms of the verbal‐efficiency theory, according to which rapid and accurate lower‐level processing liberates resources for equally crucial higher‐level comprehension processing, ultimately resulting in more efficient text comprehension.
