Fig. 4: Diminished reward effect on backward replay is associated with trait anxiety.
From: Trait anxiety is associated with reduced reward-related replay at rest

a A selective increase in backward replay after value learning is statistically significant, negatively correlated with individual trait anxiety (Pearson correlation: r (66) = −0.27, p = 0.029, 95% CI = [−0.47, −0.03], two-sided). The scatter plot is shown on the left, and the low vs. high anxiety group comparison is shown on the right. The dashed line is the \({P}_{{FWE}}\) = 0.05 permutation threshold after controlling for multiple comparisons. b The reward effect on replay is linked to behavioural change—there is a statistically significant positive correlation between an increase in backward replay and an increase in preference rating, specifically for reward sequence (Pearson correlation: r (66) = 0.25, p = 0.042, 95% CI = [0.01, 0.46], two-sided). Each dot is a participant, the solid line represents the best linear fit, with the shaded area indicating SEM. *p < 0.05.
