Overriding age differences in attentional capture with top-down processing.

Two experiments investigated the influence of top-down information on adult age differences in the ability to search for singleton targets using spatial cues. In Experiment 1, both younger and older adults were equally able to use target-related top-down information (target feature predictability) to avoid attentional capture by uninformative (25% valid) cues. However, during informative (75% v...

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...

Human variation in overriding attentional capture.

Attention can be directed either voluntarily based on the goals of the individual or involuntarily "captured" by salient stimuli in the immediate environment. Although involuntary capture is a critical means of directing attention, the completion of many common tasks requires our ability to ignore salient, but otherwise irrelevant stimuli while restricting our attention to stimuli that are rela...

Top-down influences on attentional capture by color changes.

Previous studies have shown that a change in an existing object is not as effective in capturing attention as the appearance of a new object. This view was recently challenged by Lu and Zhou (Psychonomic Bulletin and Review 12:567-572, 2005), who found strong capture effects for an object changing its color. We suspected that this finding critically depends on a procedural particularity in Lu a...

Top-down search strategies cannot override attentional capture.

Bacon and Egeth (1994) have claimed that color singletons do not interfere with search for a shape singleton when, instead of using a singleton detection mode, participants are forced to use a feature search mode. Bacon and Egeth induced a feature search mode by adding different shape singletons to the display so that observers could not simply respond to uniqueness to find the target. We did e...
