Neural Correlates of Visual Attentional Capture
摘要
Abstract
Objective To investigate the neural network activities of attentional capture during a visual search task with spatiotempo -ral patterns of ERP .Methods Fifteen subjects were asked to search and judge a specific target from 8 items,and an irrelevant color ( red or green) singleton distractor appeared on 50%of trials.Paired t-test was carried out for behavior performance and ERP data .Results The reaction time was significantly slower for the salient distractor (791.20 ±62.22 ms) compared with that of the non-salient one (772.40 ±53.77 ms):t(14)=4.26,P<0.001.The statistical parametric mapping of t -value of ERP revealed significant activations in the right-lateralized frontal-parietal-temporal area(140-180 ms),the occipital and central fronto-parietal(220-260 ms),as well as the bilateral frontal areas(360-460 ms).Conclusion The salient distractor results in attentional capture in behavioral performance . The right ventral attentional network is activated before the dorsal attentional network ,and the activations in both networks are the neural underpinnings of attentional capture .关键词
