Distractor-elicited ERPs in plant target conditions. A, The posterior lateral ERPs elicited by a scene containing a peripheral neutral distractor. B, The ERPs elicited by a scene containing a peripheral reward-associated distractor. C, The ERPs elicited by a scene containing a peripheral neutral distractor when a reward-associated distractor is present in the center of the scene. D, The ERPs elicited by a scene containing a peripheral reward-associated distractor when a neutral distractor is present in the center of the scene. E, Contralateral-minus-ipsilateral difference waves for the ERPs illustrated in A, B. The N2pc is reflected in negative deflection of the difference wave, and the Pd is reflected in positive deflection. F, Difference waves for the ERPs illustrated in C, D. Topographic maps reflect the conditional difference in voltage observed in the intervals identified by gray shading in the difference waves. The electrodes included in the calculation of ipsilateral and contralateral waveforms are identified by larger marker.
