Figure Lengend Snippet: a, b, ERP results for both the report (top row; a) and the no-report (bottom row; b) conditions. For both condition, topographical voltage distributions over a series of time windows (difference between visible and masked) and the waveforms (for both visible and masked stimuli) from a pool of central-parietal electrodes are plotted. A clear P3b was present in the report condition when observers were aware of the task-relevant stimulus, but the P3b completely vanished in the no-report condition when these same stimuli were task irrelevant. Amplitude scales for the topography maps are as follows: ±4 µV (P1); ±5 µV (N1/P2); ±6 µV (P3b in report condition); ±4 µV (P3b in no-report condition).

Figure Lengend Snippet: a, b, Results from the mass univariate analyses for both the report (a) and the no-report (b) condition. Each individual electrode is plotted as a row on the y-axis, while time (in milliseconds) is plotted on the x-axis. Only significant t values (5% FDR) are plotted in the figure.

Figure Lengend Snippet: a, b, ERP results for both the report (top row; a) and the no-report (bottom row; b) conditions. For both conditions, topographical voltage distributions over a series of time windows (difference between visible and masked) and the waveforms (for both visible and masked stimuli) from a representative electrode (Pz) are plotted. A clear P3b was present in the report condition when observers were presented a task-relevant stimulus, but the P3b completely vanished in the no-report condition when these same stimuli were task irrelevant. Amplitude scales for the topography maps are as follows: ±4 µV (P1); ±5 µV (N1/P2); ±4 µV (P3b). Note that in this experiment, a posterior N1 was elicited by both stimuli and blanks (fixation dot offset), thus N1 amplitude differences (stimulus minus blank) were much smaller than in experiment 1.

Each individual electrode is plotted as a row on the y-axis, while time (in milliseconds) is plotted on the x-axis. Only significant t values (5% FDR) are plotted in the figure. Note that the absence of a posterior N1 (160–200 ms) was due to both stimulus and blank trials eliciting an N1.
