Statistics of ROIs (green & red areas). Note that exclusive masking only excludes voxels showing an attentional effect of pure visual stimulation at an uncorrected p-value of 0.05, but importantly does not affect p-values of the functional contrast. (http://www.fil.ion.ucl.ac.uk/spm/doc/manual/manual.pdf). (*) values for the ACC were revealed with an F-test over effects of interest centered on a 10mm sphere around the anatomical ACC center (x,y,z=6,6,45, see Fan et al., 2008; Picard and Strick, 2001)
