Top-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 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 کاملDimension-based attention modulates feed-forward visual processing.
In his position paper, Theeuwes (2010) makes a challenge to a number of current theories of visual selective attention, which assume that what we select in the first instance is not simply bottom-up driven by properties of the stimulus, but also influenced (at least to some extent) by internal system settings that are under top-down control. In essence, Theeuwes (2010) puts forward a strong sti...
متن کاملPredictive Feed Forward Stereo Processing
at which control information is made available will be more crucial than the time taken to build and update the environmental model. For these reasons it would seem natural to build a dynamic vision system for autonomous navigation with two loosely connected components with very different temporal rates that reflect their required behaviours. This approach follows roughly the ideas of a subsump...
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...
