b) Main effect of Task: Perception vs. Production

Note. Regions reported at the maximum t-value peak Talairach coordinates at a p-value of .05 and a corrected cluster size at an alpha of .05 (> 171 voxels) are denoted with *. For the largest clusters we also report subpeak Talairach coordinates within those clusters. Regions that were significant for a restricted search space in a mask of language areas (LSTG, LMTG, LIFG, LMFG, LIPL) and have been corrected at a cluster size threshold p of .05 and an alpha of .05 (> 78 voxels) are denoted with **. The caudate and cerebellum clusters are uncorrected for whole brain.

No significant interactions between condition and task were found for the ANOVA (Related, Unrelated) X (Perception, Production). A large area that showed greater activation for Production compared to Perception, at p-value of = .05 encompassed multiple brain regions, making it difficult to report individual brain areas. Therefore, the results presented in part b of the Table below are reported at a threshold of p = .00001.³
