Figure 3. Event-related potentials (ERPs).

Figure 3

This panel shows ERPs (1–30Hz) to attended (black line) and unattended (green line) deviant tones at Fz (A) and Cz (B) at time 1 (thin line) and time 2 (thick line), separately for the novices (on the left) and the practitioners (on the right). In line with previous studies a smaller P200 (averaged between 150–300ms) was observed to attended vs. unattended deviant tones (main effect of condition, t(1,30)>6.4, p<1.10^−6 above Fz and Cz). The amplitude of the P200 increased across conditions only for the practitioners at time 2 (t(1,13)>2.7, p<0.05 over Fz and Cz). Note that in line with previous studies, attended target tones elicited a bigger P3a than unattended tones (main effect of Condition over electrode Fz, t(1,29)=4.3, p<0.0002, for all participants across sessions).
