Figure 3: fMRI signal for parametric predictors only included in bisected triplets. All contrasts were thresholded
at p = .001, voxelwise uncorrected, and minimal cluster size set to k = 10. Red coloured regions indicate voxels
showing stronger signal for triplets not part of a multiplication table. Green coloured regions represent voxels
showing stronger signal for triplets part of a multiplication table.
Table 6: Brain areas activated by distance to correct mean (all p < 0.001, voxelwise uncorrected)
Small distance to correct response > large distance to correct response
