Table 2.
Areas that showed task or stimulus condition by group interaction in the whole brain analysis. Because this was not a full factorial design, for appropriate comparisons, modality refers to the print vs. speech effect for the category task only; task includes only the printed word reading trials within the semantic and phonological tasks; and lexicality includes words and non-words in the phonology task only. X/Y/Z refer to coordinates of the peak activation in MNI space. P refers to the peak p-value within the region. Volume includes all voxels above threshold.
