Mounting evidence has shown that a task-irrelevant, previously reward-associated stimulus can capture attention even when attending to this stimulus impairs the processing of the current target. Here we investigate whether a stimulus that merely signals the availability of reward could capture attention and interfere with target processing when it is located outside of attentional focus. In three experiments, a target was always presented at the bottom of the lower visual field to attract focal attention. Read More

Distractor stimuli possessing information that is relevant for a task (henceforth, task-relevant distractors) often interfere with task performance. The interference by task-relevant distractors is observed even when distractors are positioned outside the main attentional focus. We investigated whether such interference is due to an attention capture by the distractors. Read More

When a visual distractor appears earlier than a visual target in a target-detection task, response time is faster if the distractor appears at the same location as the target. When a visual distractor appears concurrently with a visual target in a target-detection task, response time is slowed relative to when no distractor is presented. Both effects have been taken as evidence of the capture of visual spatial attention, yet capture by early distractors is contingent on top-down attentional control settings (ACSs), and capture by concurrent distractors is not.

Focusing attention on a target creates a center-surround inhibition such that distractors located close to the target do not capture attention. Recent research showed that a distractor can break through this surround inhibition when associated with reward. However, the brain basis for this reward-based attention is unclear. Read More
