Grand-averaged ERPs to attended and unattended (Unatt.) stimuli in each quadrant. In all quadrants, attended stimuli elicited larger ERP amplitudes for the sensory-evoked P1 and N1 components (black waveforms) compared with the ERPs elicited by the same stimuli when unattended (red and green waveforms). N1 amplitudes (latency range indicated by yellow bar) were also enhanced by unattended stimuli in the same object condition (red waveforms) relative to the ERPs elicited by unattended stimuli belonging to a different object (green waveforms). For each quadrant, ERPs are shown from a parietal electrode site contralateral to the eliciting stimulus (P3/P4).
