Fig. 5: Pearson’s correlation plots showing associations among dependent variables in our study.

Increasing size and saturation of squares depict the effect size, negative correlations are shown in blue and positive correlations in red. BIS: Behavioral Inhibition System; BAS: Behavioral Activation System; Trait SC: Trait Self-Control Scale; LPP HA: LPP to high arousal positive images; LPP Diff Arousal: LPP difference score (high arousal − low arousal); LPP Diff Valence: LPP difference score (positive valence − negative valence); Diff ERN: ERN difference score (error − correct); RewP: Reward Positivity; Diff Rew P: RewP difference score (correct − error); Diff RT: reaction time difference on the flanker task (incompatible–compatible); Diff Errors: error rate difference on the flanker task (incompatible–compatible).
