Analysis of N1 responses associated with attentional filtering. A, Left, Scalp distribution of evoked potentials at 150 ms, revealing strong responses over occipital sensors (black box). Right, Grand average waveforms at occipital sensors for self-control success (black), noncontrol (dashed), and self-control failure (gray) in NC and SCC sessions, displaying the visual N1 deflection at ∼170 ms poststimulus onset. B, Mean evoked amplitude (μV) for self-control success (black), noncontrol (white), and self-control failure (gray) at occipital sensors from 150 to 200 ms in the NC versus SCC session. Error bars reflect SEM. *p < 0.05.
