Local and global effects in individual subjects. (Left) Each horizontal line summarizes an individual subject t test statistics (left for the local effect; right for the global effect). Individual statistics are plotted for 10 subjects from each of the Counting (top), Mind-wandering (middle) and Visual interference (bottom) groups. (Right) For each group, we computed a mean individual statistical index by defining linear bins of individual t test statistical significance (0 for P > 0.05; 1 for P < 0.05; 2 for P < 0.01; 3 for P < 0.005; 4 for P < 0.001; 5 for P < 0.0005; and 6 for P < 0.0001).
