摘要
成语中某一字出错作为应检测信号，正确成语作为噪音，实验时间为１００分钟，分成五个相等的时间段。结果发现，（１）四种音形条件下平均正检率在第一时间段明显上升然后保持平稳，反应时随时间变化不显著但音异形假在第一阶段与音同形异在第五阶段的反应时间明显长于其余时间阶段。（２）四种音形条件下正检率有差异，从高到低依次为：音同形似、音同形异、音异形似、音异形假．（３）音形与时间段在正确率上无交互作用，在反应时间上存在交互作用。
Four-Chinese -character idioms of high frequency of use were used in the experiment. The first characters in the 440 idioms altered in phoneme, script orboth were to be detected as the signal idioms. Theother 1320 idioms were noise. The 100mins experiment was divided into 5 equal sections. There was nobreak between sections. The result showed that thecorrect rate went up significantly during the firsttwenty minutes and remained stable during the subsequent eighty minutes. No interaction was observed between phoneme or script and time. The response timesignificantly declined during the first 20mins under thefaulty but similar script condition and significantly increased during the last 20mins under differentphoneme and similar script conditions. The responsetime under other phoneme and script conditions keptstable throughout the 100mins experiment time.
