All test statistics are with (1,206) degrees of freedom. Underlined effects are reversed in direction (i.e., the reversed effect from L > R × F > P is L < R × F > P). Changing the direction of both directional indicators within a single effect is equivalent (i.e., L > R × F > P is the same as L < R × F < P). L, left; R, right; M, midline; F, frontal; P, posterior; C, central. Significant results are printed in bold.
