ABSTRACT
The present study tested the hypothesis that underlying orthographic representations vary in completeness within the individual, which is manifested in both spelling accuracy and reading speed. Undergraduate students were trained to improve their spelling of difficult words. Word reading speed was then measured for these same words, allowing for a direct evaluation of whether improvements in spelling would bring about faster reading speeds. Results were clear: Spelling accuracy and reading speed were strongly related across and within participants. Most important, words that improved in spelling accuracy were read more rapidly at posttest than words that did not show improvement in spelling. These results provide direct evidence showing that the quality of orthographic representations, as indexed by spelling accuracy, directly relates to reading speed. This is consistent with the lexical quality hypothesis and highlights the relevance of spelling in literacy acquisition.

Notes
1 Note that there were too few instances of inconsistent spelling (10.2%) to permit a separate analysis of this category of performance (see also Martin-Chang et al., Citation2014).
