FIGURE 3.

(A) Representation of task-to-rest subtraction in correlation values ( $∆r)$ . Edges are traced when $∆r$ surpassed the positive and negative thresholds. Red lines indicate an increase in correlation values and the negative ones a decrease. For sex condition: $+Th=\mathit{0.04}$ and $-Th=-\mathit{0.04}$ . For happiness: $+Th=\mathit{0.03}$ and $-Th=-\mathit{0.05}$ . (B) Age differences in cumulative distribution curves of task-to-rest subtraction for each task. Dotted arrows indicate the thresholds used for tracing the graphs.
