Figure 1. Proportion of predicted beliefs being less than the true beliefs under different behavioral decision conditions.

Figure 2. (a) Average ERPs of P4 under different behavioral decision conditions. The gray bar in the figure indicates the time window of P2 (100-200 ms). (b) Brain topographic maps of P2 under each condition. (c, d) Bar graphs show the average P2 values under deception and honesty conditions across different brain regions and hemispheres. Error bars represent the standard error of the mean.

Figure 3. (a) Average ERPs of Pz under different behavioral decision conditions. The gray bar in the figure indicates the time window of N2 (150-250 ms). (b) Brain topographic maps of N2 under each condition. (c, d) Bar graphs show the average N2 values under deception and honesty conditions across different brain regions and hemispheres. Error bars represent the standard error of the mean.

Figure 4. Proportion of predicted beliefs being less than the true beliefs under different conditions.

Figure 5. (a) Average ERPs of CPz and Cz under different behavioral decision conditions. The gray bar in the CPz figure indicates the time window of N1 (20-80 ms), and the gray bar in the Cz figure indicates the time window of P2 (100-200 ms). (b) Brain topographic maps of N1 and P2 under each condition. (c) Bar graphs show the average N1 and P2 values under different conditions. Error bars represent the standard error of the mean.

Figure 6. (a) Average ERPs of Pz and P4 under different behavioral decision conditions. The gray bar in the Pz figure indicates the time window of N2 (150-250 ms), and the gray bar in the P4 figure indicates the time window of P300 (200-300 ms). (b) Brain topographic maps of N2 and P300 under each condition. (c) Bar graphs show the average N2 and P300 values under different conditions. Error bars represent the standard error of the mean.
