Figure 1.

(a) Illustration of experimental paradigm. Upper panel: in the opportunity trials, participants first memorized the color of the circle (yellow or blue), and choose the color they previously saw. Misreporting the color earned participants more money than reporting correctly. Lower panel: in the test trials, participants were required to report the color correctly. (b) Distribution of lying percentages across participants (N = 37). (c) Negative correlations were found between lying percentages and reaction time of lying (red dots and solid line; Spearman correlation: r = −0.45, p = .03). No significant correlation was found between lying percentages and reaction time of truth‐telling (green dots and dashed line; Spearman correlation: r = −0.02, p = .92; N = 23) [Color figure can be viewed at https://wileyonlinelibrary.com]
