A method for analyzing reaction times (RTs) in tasks involving both sequential and concurrent processing is proposed. Tasks are analyzed with the method by selectively prolonging mental processes, as with the additive factor method. Falsifiable predictions about the changes in RT produced by prolonging processes are derived by drawing on the theory of scheduling. Under certain conditions, which frequently arise in practice, one can determine for a given pair of processes whether they are executed sequentially or concurrently. If one process precedes another, one can often determine which comes first. One can also construct intervals within which the process durations lie. Two experiments are analyzed using the method. One, by Holyoak, Dumais, and Moyer, is on a sentence-verification task involving associated and unassociated items. The other experiment is on the Stroop effect and supports the single-channel hypothesis that a subject makes only one decision at a time. The data suggest that in the color-naming task the decision about the word precedes the decision about the color, whereas in the word-naming task the order of the decisions is reversed.
提出了一种用于分析涉及顺序处理和并发处理任务中反应时间（RTs）的方法。通过选择性地延长心理过程，如使用加法因素法，用该方法对任务进行分析。通过借鉴调度理论得出关于延长过程所产生的反应时间变化的可证伪预测。在实践中经常出现的某些条件下，可以确定给定的一对过程是顺序执行还是并发执行。如果一个过程先于另一个过程，通常可以确定哪个先出现。还可以构建过程持续时间所在的区间。使用该方法分析了两个实验。一个是由霍利约克、杜梅斯和莫耶进行的，关于涉及相关和不相关项目的句子验证任务。另一个实验是关于斯特鲁普效应的，支持单通道假设，即受试者一次只做出一个决定。数据表明，在颜色命名任务中，关于单词的决定先于关于颜色的决定，而在单词命名任务中，决定的顺序则相反。
