| 摘 要： | 在Stroop启动范式中,启动刺激是灰色的色词,目标刺激是颜色块,被试的任务是命名颜色块的颜色。本研究通过行为实验和事件相关电位(ERP)实验的方法,研究SOA(Stimulus Onset Asynchrony)对Stroop启动效应的影响。当SOA为107ms时,在行为数据(反应时)和ERP数据(N300成分)上均表现出明显的启动效应;当SOA为1040ms时,行为上和ERP上的启动效应消失。该结果提示了在Stroop启动效应中,启动刺激对目标刺激的影响很可能是发生在对目标刺激的知觉加工晚期。 |

| Abstract: | In the Stroop priming paradigm,the color word is presented as the prime,and then the color patch as the target,and the subject's task is to name the color of the color patch.Through behavioral measures and event-related potentials(ERPs) recording,the present study explored the influence of SOA(Stimulus Onset Asynchrony) on the Stroop priming effect.Both behavioral(reaction time) and ERP(N300 component) results showed a significant priming effect at SOA of 107ms,and no priming effect at SOA of 1040 ms.The results suggested that the Stroop priming effect might take place in the late perceptual processing stage. |
