目的 利用事件相关电位(event-related potentials,ERP)时空模式考察客体颜色突出性和行为相关性的神经加工机制.方法 20名被试完成Eriksen范式的19通道ERP记录.各刺激图片由三个并列符号构成:中央靶(灰色箭头或X符)分别提示对应侧按键或抑制反应,两侧分心物由其行为相关性(箭头—易化,X符—抑制,H符—无关)和颜色突出性(红色或灰色)分类.结果 反应时间的分心物交互效应显著(F(1.85,35.21)=13.015,P＜0.001);易化组的颜色突出性[红色:(411.91±40.39) ms;灰色:(420.42±38.58)ms]差异显著(t(19)=-4.858,P＜0.001).ERP的F值统计参数映像提示:颜色突出性效应相继出现在右颞枕区(100～125 ms)、背侧注意网络(DAN)(150～300 ms)和腹侧注意网络(VAN) (300～450 ms);分心物行为相关性效应出现在枕区(150～ 200 ms)、VAN(200～ 300 ms)和DAN(300～600 ms);靶与分心物行为相关性交互效应出现在DAN(200～ 350 ms).结论 分心物颜色突出性和行为相关性信息分别在不同时段进入VAN和DAN等注意子网络.DAN的ERP效应可能是条件注意捕获效应的神经相关.

Objective To investigate the neural processing of stimulus salience and behavioral relevance with spatiotemporal patterns of event-related potentials (ERP).Methods The ERP was recorded from 20 subjects while they performed Eriksen task.Each stimulus picture contained 3 symbols:a central target (grey symbol "＜"/ "＞" or "X") represented pressing the corresponding button or withdrawing response respectively.And the flanking distractors were classified by both behavioral relevance (" ＜"/" ＞"-facilitory,"X"-inhibitory,"H"-irrelevant) and color salience (red,grey).Results Significant interaction effect was found for the reaction time(F(1.85,3521)=13.015,P＜0.001).Significant difference was found between the salient ((411.91 ±40.39) ms) and the non-salient ((420.42±38.58) ms) under the facilitory condition(t (19) =-4.858,P＜0.001).The significant ERP effects were revealed by statistical parametric mapping of F-value.The saliency effects appeared in the right occipital-temporal regions (100-125 ms),the bilateral dorsal attentional network (DAN) (150-300 ms) and the right-lateralized ventral attentional network (VAN) (300-450 ms).The effects of the behavioral relevance occurred in the occipital regions (150-200 ms),the VAN (200-300 ms) and the DAN (300-600 ms).The interaction effects of behavioral relevance between the target and the distractor occurred in the DAN (200-350 ms).Conclusion The information of the distractor salience and behavioral relevance access VAN and DAN in different stages respectively.The ERP effect in the DAN may be the neural correlation of contingent attentional capture.
