The second and third sentences of the first paragraph of the General Behavioral Performance section of the results were incorrectly merged. The correct sentences are: Across subjects, the mean and median go trial RT were 393.6±59.7 (mean ± SD) and 376.8±60.5 ms, respectively, consistent with a right-skewed distribution of RT in an RT task [34]. The rate of successful stop trials was 48.6±2.3%, suggesting the success of the staircase procedure in eliciting errors in approximately half of the stop trials.

Table 1 and Table 2 are incorrect. The correct Table 1 and Table 2 are below.

Figure 4 is incorrect. The authors have provided a corrected version here.

Figure 4. ERP curves during stop and go trials at Cz and Pz channels, time-locked to button press (at 0 ms).

The peak-to-peak analysis showed that ERN occurred in both SEi and SEni trials at Pz, compared to G trials. Furthermore, signed-rank test showed that ERN was greater in SEni than SEi trials at Pz. On the other hand, the peak-to-peak analysis showed that Pe occurred in both SEi (at Cz and Pz) and SEni (at Pz), compared to G trials. Furthermore, signed-rank test showed that Pe was greater in SEi than SEni at Cz. These results showed that the amplitude of Pe, not ERN, increased in stop error trials immediately preceding go trials with RT slowing.
