Figure 1. Scatter diagrams of Effortful Control Scale (ECS) score and Driving Behavior Questionnaire (DBQ) scores.

Panels A, B and C denote DBQ scores for violations, errors and lapses, respectively, during daily driving. Each dot represents each participant. Asterisks indicate statistically significant correlations (P<0.05/3; one-tailed Pearson's correlation test adjusted by the Bonferroni correction for multiple comparisons).
