Initial cluster sizes are given for P < 0.005 and a cluster extent of at least 25 voxels.
a
Resulting cluster size for a P < 0.001 threshold.
b
Resulting cluster size for a FWE‐corrected threshold of P < 0.05.
No. of sig. voxels = the number of voxels which differ significantly between both conditions. Peak coordinates (x, y, and z) are displayed in MNI space. A cluster may exhibit more than one peak, while only the largest peak is reported. Area = peak brain region as identified by the LONI atlas. R/L = laterality right or left.
G = Gyrus; Inf = inferior, Mid = middle, Sup = superior.
Within significant main effects of attention, post hoc differences were only found for the comparison attended > unattended
