Abstract: 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

Key words: conflict control, delta plot, RT distribution analysis
