Regions for each contrast were identified using p<0.005 in a random-effects voxelwise analysis and cluster size threshold of 5 functional voxels of 3 mm³ each. “-“ signifies that no activation was observed that met threshold. Activated areas for the contrast [2D Different > 2D Repeat] (i.e., 2D-repetition effects) was extensive and is therefore displayed in Figure 4 .
