Observers in the reverse condition. A. Mean voltage values of the three midline electrodes (Fz, Cz, Pz) of the four different conditions (max gain, min gain, max loss, min loss) for the observers in the reverse condition in the 250-290 ms interval. Note that, as in the rest of the paper, loss and gain refers to the performer. Hence the pattern is opposite to the one shown in Figure 2A, because loss refers to a gain in the observer and vice-versa. B. Scalp voltage distribution of the max loss minus max gain condition (left) and the min loss minus min gain (right). Note the inversion of the effects on the scalp (in this condition loss minus gain in the performer corresponds to gain minus loss in the observer) and the difference in the scales in the two condition (maximum condition: - 1.5 to 1.5 μV; minimum condition: -0.8 to 0.8 μV).
