ERP results from Experiment 2. (A) The scalp topography of the difference waveform between loss and win trials, and between incorrect and correct trials. (B) ERP at electrode Fz. Gray shaded areas denote the FRN (250–350 ms) and LPP (500–800 ms) intervals. Blue: win. Yellow: loss. Solid line: correct. Dashed line: incorrect. (C) Difference waveforms. Red: congruent/salient. Gray: incongruent/non-salient. Solid lines denote loss–win whereas dashed lines denote incorrect–correct. (D) ERP at electrode Pz. Gray shaded area denotes the P300 (350–450 ms) interval. (E) Mean amplitude of difference for the FRN. (F) Mean amplitude of difference for the LPP. (G) Mean amplitude of difference for the P300. Error bars denote one SEM across participants. Asterisk indicates a significant difference using two-tailed one-sample t-test: ⁺P < 0.1, *P < 0.05, and **P < 0.01. n.s.: not significant. Red: congruent/salient. Gray: incongruent/non-salient. Solid bars denote loss–win whereas open bars denote incorrect–correct. ERP, event-related potential;  FRN, feedback-related negativity; LPP, late positive potential.
