ERP in Response to the Parallel Lines Oddball Task, 380 ms post-stimulus.

<p>380 ms after stimulus presentation, amplitude at site F8 is relatively more negative after the deviant stimulus (B), as compared to the standard stimulus (A). Amplitude at site Pz is relatively more positive after the deviant stimulus (D), compared to the standard stimulus (C).</p

ERP in Response to the Parallel Lines Oddball Task, 200 ms post-stimulus.

<p>200 ms after stimulus presentation, amplitude at site F7 is relatively more positive after the deviant stimulus (B), as compared to the standard stimulus (A). Negativity is observed at electrode site P7 after the deviant stimulus (D), but not after the standard stimulus.</p

Differences in Performance on the OC-CIT.

<p>Subjects had significantly higher reaction times (A) and made significantly more errors (B) during the congruent sorting task than during the incongruent sorting task, regardless of the ordering of these tasks. Bars represent mean ± standard error. Asterisks indicate a significant (<i>p</i><0.05) difference between the bars for the congruent and incongruent tasks.</p
