In the low-depression group, σ values also increased in association with those valence and arousal scores (see the left panels of Figure 4 ), resulting in a significant positive correlation (Pearson correlation coefficient) between the arousal scores and σ values ( r (28) = 0.40, p = 0.028) and a marginally significant correlation between the valence scores and σ values ( r (28) = 0.32, p = 0.083).
