Contingent attentional capture by conceptually relevant images.
Attentional capture is an unintentional shift of visuospatial attention to the location of a distractor that is either highly salient, or relevant to the current task set. The latter situation is referred to as contingent capture, in that the effect is contingent on a match between characteristics of the stimuli and the task-defined attentional-control settings of the viewer. Contingent capture...
متن کاملTop-down contingent attentional capture during feed-forward visual processing.
Theeuwes (2010) summarizes an impressive number of studies demonstrating interference by irrelevant visual singletons in computer experiments with humans. In these studies, if participants search for a relevant singleton target, such as the single diamond among circles (i.e., a shape singleton), an irrelevant singleton distractor, such as the single red circle among the green stimuli (i.e., a c...
متن کاملDistractor-Induced Blindness: A Special Case of Contingent Attentional Capture?
The detection of a salient visual target embedded in a rapid serial visual presentation (RSVP) can be severely affected if target-like distractors are presented previously. This phenomenon, known as distractor-induced blindness (DIB), shares the prerequisites of contingent attentional capture (Folk, Remington, & Johnston, 1992). In both, target processing is transiently impaired by the presenta...
متن کاملMade you blink! Contingent attentional capture produces a spatial blink.
Previous studies have shown that the capture of attention by an irrelevant stimulus can be eliminated by fore knowledge of the spatial location of the relevant target stimulus. To explore whether spatial certainty is sufficient to eliminate capture, four experiments are reported in which the spatial location of the target is certain but the temporal position is uncertain. Subjects viewed a cent...
متن کاملContingent attentional capture by top-down control settings: converging evidence from event-related potentials.
Theories of attentional control are divided over whether the capture of spatial attention depends primarily on stimulus salience or is contingent on attentional control settings induced by task demands. The authors addressed this issue using the N2-posterior- contralateral (N2pc) effect, a component of the event-related brain potential thought to reflect attentional allocation. They presented a...
