Attentional capture by irrelevant transients leads to perceptual errors in a competitive change detection task

摘要: Theories on visual change detection imply that attention is a necessary but not sufficient prerequisite for aware perception. Misguidance of due to salient irrelevant distractors can therefore lead severe deficits in detection. The present study investigates the mechanisms behind such perceptual errors and their relation error processing higher cognitive levels. Participants had detect luminance occasionally occurred simultaneously with an orientation opposite hemi-field (conflict condition). By analyzing event-related potentials EEG separately those prone conflict trials correct erroneous detection, we demonstrate only was associated allocation relevant change. Erroneous initial capture toward N1 time window lack subsequent target selection processes (N2pc). Errors were additionally accompanied by increase fronto-central N2 kind negativity (Ne or ERN), which, however, peaked prior response. These results suggest strong disrupt further information thus affect its Yet, it does impair indicating these are independent from awareness.
