Table 5.
The effects of phonological vs. semantic inputs. Separate tables indicate the location and significance of activation for: (A) stimuli with phonological vs. non-phonological content; (B) stimuli with semantic vs. non-semantic content; and (C) auditory stimuli with semantic content.

The first column (C) reports the contrast number used in Table 1. The second column gives the anatomical name of the location of the activation using abbreviations explained in Table 4. The third column indicates the hemisphere (H), either left (L), or right (R). The fourth column gives the x, y, and z co-ordinates of the peak activation in MNI space. The last five columns give the Z scores for the effect of interest over task contrast OB&SP, OB only, SP only, OB > SP, and SP > OB. Note that the latter two effects indicate the interaction of task with the effect of interest (phonology or semantics). The main effect of task (over semantic and phonological stimuli) is reported Table 6. Effects that survived family wise error correction for multiple comparisons are marked “*” and “∧” for height and extent, respectively. Effects that were not significant at p < 0.01 uncorrected are marked ns.
