Attention selection, distractor suppression and N2pc

open access: yesCortex, 2009
N2pc is generally interpreted as the electrocortical correlate of the distractor-suppression mechanisms through which attention selection takes place in humans. Here, we present data that challenge this common N2pc interpretation. In Experiment 1, multiple distractors induced greater N2pc amplitudes even when they facilitated target identification ...

Temporal variability of the N2pc during efficient and inefficient visual search

open access: yesNeuropsychologia, 2012
Efficient and inefficient visual search are characterized by the difference in the time required to find the target. Efficient "popout" search time is relatively unaffected by increases in the number of search items, whereas inefficient "non-popout" search time requires more time increases in duration.

The effect of modulating top-down attention deployment on the N2pc/PCN

open access: yesBiological Psychology, 2016
The N2pc (PCN) component of the event-related potential (ERP) waveform provides a useful tool for directly assessing the locus of spatial attention in visual search. It is still unclear whether the amplitude of the N2pc/PCN relates to the deployment of attentional resources.
