Delta图分析方法及其在冲突控制研究中的应用

Delta Plot Analysis and Its Use in Conflict Control Studies

近年来，反应时分布分析方法被应用于冲突控制研究领域，以弥补只计算平均反应时和错误率的不足。所谓delta指的是不一致条件与一致条件反应时之差，即冲突效应量。冲突效应量随反应时间的变化图称为delta图。与该分析方法相应的理论模型包括双通路模型和激活－抑制模型。本文介绍了delta图分析的具体方法及其与冲突控制理论模型的关系，然后列举了有关的研究例证，并强调了其优缺点与适用范围。

In recent years， the reaction time (RT) distribution analysis was used in conflict control researches. The delta plot could depict the difference of RTs between incongruent and congruent conditions as a function of mean RT. This analysis method was used to examine some hypothesis while the traditional mean RT and error rate could not. This paper introduced the method of this analysis and its relative theoretical model， and overviewed the studies using this analysis method.
