Grand-averaged ERPs recorded at parieto-occipital electrode sites (pool of PO3/4 and PO7/8), time-locked to the onset of the search display. Shown are the difference waves (contralateral minus ipsilateral activity) elicited by lateral targets (top) and lateral distractors (bottom), separately for trials with a neutral target (black lines) and trials with an addiction-relevant target (blue/light grey lines) and for casual gamers (left column) and the IGD group (right column). For illustration purposes, the waveforms were lowpass filtered at 35 Hz
