摘要:
 近几年,对负启动效应的神经机制研究发现,干扰项抑制与情节提取都是引起负启动 的原因,究竟哪种机制起主要作用与实验任务有很大的关系。从现有的研究结果来看,位置负启 动与前额皮层有关,EPR 上表现为P1和N1波幅减小或N2波幅的增大,支持抑制机制。特性负启 动P3成分仍存在不一致的结果,脑区的广泛激活模式使得研究者越来越倾向采取整合的观点。
Abstract:
 In recent years ,results about the neural bases of negative pri ming effect indicatedthat both distracterinhibition and episodic retrieve are suggested to account for the negative pri ming effect .Which kind of mechanismcause NP effect will depend on experi mental tasks .The prefrontal cortex was activated inlocation negative pri ming task,which is associated with inhibition mechanismwith a decrease of P1and N1 amplitude or aincrease of N2amplitude .However ,there are some inconsistent results of P3in identity negative pri ming .Researchers are inclined to hold integration viewbecause of activation of a widespread cortical network.
