Clusters showing significant increases in activation associated with the magnitude of angle in the following contrasts: (1) the stimulus main effect, (2) the strategy main effect, (3) the stimulus × strategy interaction, and (4) the simple effect of assessing the arm's laterality while using the visual strategy against zero
