Abstract

We conducted a feasibility study to determine whether an fMRI paradigm could be used to address the controversy about whether reading and spelling rely on the same orthographic lexical representations. Specifically, we explored whether reading and spelling tasks produced overlapping patterns of neural activation in a within-subjects experimental design. Results showed that a cortical region corresponding to the “visual word form area” is involved not only in orthographic processing in reading but also in retrieval of orthographic information for spelling. These findings demonstrate the utility of this technique and suggest that a single orthographic lexicon mediates both reading and spelling.
