Figure A3.

Topographic maps of mean P300 difference waves (non-CSD-transformed ERPs to targets minus those to non-targets) during 400–500 ms in the scrambled and comprehension conditions. (A) For good comprehenders. (B) For poor comprehenders. Warmer colors indicate more positive voltage differences, cooler colors indicate more negative voltage differences (see color bar to the right of the figure). Left column: scrambled condition. Middle column: comprehension condition. Right column: difference map (scrambled condition minus comprehension condition).
