Stimulus intensity a ¡ ects the latency but not the amplitude of the N 2 pc


The N2pc component of the event-related potential (ERP) is an index of visual^ spatial attention. It is not clear whether the N2pc re£ects pure top-down attentional activity or an interaction of top-down activity with bottom-up sensory activity. Here, we manipulated stimulus intensity of the items composing the target display. Although the amplitude of the… (More)
