Abstract: The current study is to explore the impact of stimulus repetition quantities on after-effects of response inhibition. The participants were instructed to perform the Stop-signal tasks with different stimulus repetition quantities. The results indicated that the reaction time of stimulus repetition quantities was significant and the repeated types were not significant. In successful response inhibition,the reaction time of no-signal trials after different stimulus repetition quantities were not significantly different from those after no-signal trials. In unsuccessful response inhibition, the reaction time of no-signal trials after different stimulus repetition quantities significantly different from that of after no-signal trials. These findings suggested that after-effects of response inhibition reflected executive process of cognitive control rather than memory retrieval of automaticity.

Key words: stimulus repetition quantities, after-effects of response inhibition, cognitive control theories, theories of automaticity

摘要： 本研究为了探讨不同刺激重复量对反应抑制后效应的影响。在不同刺激重复量条件下,让被试完成停止信号任务。结果发现,从总体来看,刺激重复量因素上的主效应显著,重复类型因素上主效应不显著;信号抑制条件下不同刺激重复量后无信号试次反应时与总的无信号试次反应时差异不显著;信号反应条件下不同刺激重复量后无信号试次反应时与总的无信号试次反应时差异显著。本研究表明不同刺激重复量条件下的反应抑制后效应是认知控制的执行加工而非自动化的记忆提取。
