Figure 2.

Grand averaged ERP waveforms over all subjects at electrodes C1, Cz, and C2 for motor-only with zero delay (MO_P, dashed line) task, original motor-vocal task with zero delay (MVP, thin solid line), and corrected motor-vocal task with zero delay (MVP_A, thick solid line). The response for the MVP_A condition was calculated by a subtraction of the response for the MO_P condition from that for the MVP condition.
