Writing nonsense: the interaction between lexical and sublexical knowledge in the priming of nonword spelling

The task of spelling nonwords to dictation necessarily requires the operation of a sublexical or assembled sound-to-spelling conversion process. We report an experiment that shows a clear lexical priming effect on nonword spelling (e.g., /vi:m/ was spelled as VEME more often following the prime word "theme" and as VEAM more often following "dream"), which was larger for lexically low-probability (or low-contingency) than for common (or high-contingency) spellings. Priming diminished when an unrelated word intervened between the prime word and target nonword and did so more for the production of low- than for high-contingency spellings. We interpret these results within an interactive model of spelling production that proposes feedback from the graphemic level to both the lexical and assembled spelling processes.
