Attentional capture with rapidly changing attentional control settings.
The classic theory of spatial attention hypothesized 2 modes, voluntary and involuntary. Folk, Remington, and Johnston (1992) reported that even involuntary attention capture by stimuli requires a match between stimulus properties and what the observer is looking for. This surprising conclusion has been confirmed by many subsequent studies. In these studies, however, the observer typically look...
متن کاملContingent 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 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...
متن کاملStimulus-driven attentional capture and attentional control settings.
Jonides and Yantis (1988) found that abrupt-onset singletons capture attention in visual search when onset is orthogonal to the target's defining and reported attributes and that color and brightness singletons do not. They concluded that abrupt onset may be unique in capturing visual attention. Folk, Remington, and Johnston (1992) challenge this conclusion and argue that (a) the occurrence of ...
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...
