How about Lunch? Consequences of the Meal Context on Cognition and Emotion
Left panel: ERPs at electrode Cz, superimposed for correct and incorrect (corr., incorr.) responses and pre-meal and post-meal sessions (S1, S2) and for the Experimental and Control group. Topographies of the Ne as the difference between incorrect and correct responses are depicted to the right of the waveforms. Right panel: Same as left panel but for electrode Pz (please note changes in voltage and time scales). Topographies of error positivities (350-550 ms) are shown to the right of the waveforms.
