Summary: Research has shown that active suppression of salient distractors is a crucial aspect of visual selection. The study provides clear evidence for a spatial gradient of suppression surrounding salient singleton distractors, with target selection improving as the distance between target and distractor increases.

Summary: Physically salient but task-irrelevant stimuli have high attentional priority, but observers can use statistical regularities to better ignore them. Additionally, statistical learning can modulate attentional priority for basic shapes, not just elementary features.

Summary: Visual attention can be tuned or biased based on specific feature values or relative features of sought-after objects, driving covert attention and eye movements in visual search. The relational account of attention can be extended to explain attentional engagement and selection of continuously attended objects in time, beyond spatial attention.

Summary: Performing visual search tasks requires optimal attention deployment to promote target recognition and inhibit distractors. Rejection templates based on the feature of the distractor can be built to constrain the search process. The study found that in the fixed-cueing condition, participants were able to sustainably decode the cued colors during the retention interval, and those with higher decoding accuracy showed larger suppression benefits of distractor cueing in the search period. However, in the varied-cueing condition, the cued color could only be transiently decoded, and higher decoding accuracy was observed in participants with lower suppression benefit. The neural representations of the to-be-ignored color in the two cueing conditions and their reverse associations with behavioral performance suggest that rejection templates were formed in the fixed-cueing condition but not in the varied-cueing condition. Additionally, stronger posterior alpha lateralization and midfrontal theta/beta power were observed during the retention interval of the varied-cueing condition, indicating the cognitive costs of template formation caused by the trialwise change of distractor colors.

Summary: This study examines whether feature-based distractor regularities can be extracted automatically from a feature dimension orthogonal to the target-guiding dimension. The results provide evidence that learned distractor rejection is not influenced by the target guidance dimension, supporting recent findings on the effects of learned distractor rejection.

Summary: Salient but task-irrelevant distractors interfere less with visual search when they appear in a display region where distractors have appeared more frequently in the past. This effect can be explained by the (re-)distribution of a limited attentional inhibition resource. It is also possible that this distractor-location learning reflects a local response to distractors occurring at a particular location. The experiments conducted in this study provide evidence for purely local learning of distractor interference.

Summary: Recent research suggests that passive exposure to distractors can attenuate interference from distractors during actual visual search, potentially through habituation processes.

Summary: Research shows that in efficient search of the environment, identification of a target is enhanced when it is grouped with a suppressed distractor compared to when they are in different perceptual groups.

Summary: People can improve task performance efficiency by learning to suppress salient distractors that occur frequently at particular locations. Eye-movement studies show that reducing oculomotor capture rate is a significant factor, while there is controversy regarding the role of rapid disengagement as well.

Summary: Recently, it was found that irrelevant salient stimuli can disrupt visual search. The prevalence of the distractors can influence their impact on search processes. Two experiments were conducted to investigate the effect of distractor prevalence on the distractor-quitting threshold effect. The results showed that distractor prevalence did not modulate the effect in Experiment 1, but it did in Experiment 2.

Summary: The study found that in visual search tasks, attentional suppression can reduce interference when a salient distractor appears more frequently at a certain position, but interference may increase on low-probability positions.

Summary: Siamese networks have shown success in visual tracking, but challenges remain in precise and robust tracking. The novel Ta-ASiam network addresses this by utilizing a two-stage training strategy and feature selection module.

Summary: When searching for a shape target, distractors of different colors tend to attract our attention. However, this capture effect is smaller when the target template is specific to a certain feature and when observers can predict the distractor location. In this study, we investigated how the precision of the target template influences distractor location learning. Our results showed that with a more precise target template, there is less need for distractor location learning as the interference from distractors is reduced.

Summary: In day-to-day activities, stimulus representations in the visual cortex are modulated based on their attentional priority. This study found that the activity of subregions in the fronto-parietal dorsal attention network and the visual cortex is modulated by feature-based attentional weighting.

Summary: Recent evidence suggests that dedicated neurocognitive mechanisms exist for suppressing salient but irrelevant distractors. Additionally, statistical learning (SL) may adjust overall attentional priority but affects filtering efficiency due to distribution of targets. This study found that even conflicting target and distractor manipulations result in the adjustment of a unique spatial priority computation, likely due to direct plastic alterations of shared spatial priority maps.

Summary: Target templates stored in visual memory can guide visual attention and learned distractor rejection is achieved through proactive attentional control. The current study found that observers adopted a proactive attentional control setting to avoid distraction whenever possible, and were able to recover quickly when distraction occurred.
