Active suppression of salient-but-irrelevant stimuli does not underlie resistance to visual interference.
In visual search for a shape target, interference from salient-but-irrelevant color singletons can be resisted in feature search mode, but not in singleton detection mode. In singleton detection mode, we observed a contralateral positivity (PD) after 260-340ms, suggesting that the salient distractor was suppressed. Because RTs in singleton detection mode increased when a distractor was present,...
متن کاملLearning to suppress task-irrelevant visual stimuli with attention
While the importance of attention in perceptual learning is widely recognized, the mechanisms through which it affects learning are poorly understood. Here we show that attentional mechanisms themselves are modified during learning. Attentional suppression of task-irrelevant stimuli becomes more efficient with practice. Attentional learning was found to be stimulus-specific and to persist for s...
متن کاملSalient-but-irrelevant stimuli cause attentional capture in difficult, but attentional suppression in easy visual search.
Search for a shape target is difficult when its shape is similar to the shape of the surrounding nontargets and easy when it is dissimilar. We asked whether interference from a salient but irrelevant color singleton depended on search difficulty as manipulated by target-nontarget similarity. We found that interference was strong in difficult searches, and the occurrence of an electrophysiologic...
متن کاملThe problem of latent attentional capture: Easy visual search conceals capture by task-irrelevant abrupt onsets.
Researchers are sharply divided regarding whether irrelevant abrupt onsets capture spatial attention. Numerous studies report that they do and a roughly equal number report that they do not. This puzzle has inspired numerous attempts at reconciliation, none gaining general acceptance. The authors propose that abrupt onsets routinely capture attention, but the size of observed capture effects de...
متن کاملFacilitation of responses by task-irrelevant complex deviant stimuli.
Novel stimuli reliably attract attention, suggesting that novelty may disrupt performance when it is task-irrelevant. However, under certain circumstances novel stimuli can also elicit a general alerting response having beneficial effects on performance. In a series of experiments we investigated whether different aspects of novelty--stimulus novelty, contextual novelty, surprise, deviance, and...
