Sternberg（1969）指出，当心理过程连续执行时，延长不同过程的因素对反应时间具有累加效应。如果满足其他合理的假设，这些因素也会对误差产生近似相加的影响。在这些假设下，在一个实验中对反应时间有加性影响的因素，在另一个以相同方式进行的实验中也会有加性影响，但错误率不同。这些结果可用来增加对反应时间的分析和对准确性的分析；此外，还可以单独分析测量精度的实验。这一过程用文献报道的三个实验来说明：选择任务、词汇决策任务和记忆扫描任务。讨论了关键路径网络中过程的速度和精度。相对于时间的对数百分比的变化率可以表示为这种网络中的保守流。
Sternberg (1969) stated that when mental processes are executed in series, factors prolonging different processes have additive effects on reaction times. If additional plausible assumptions are met, such factors will also have approximately additive effects on errors. Under these assumptions, factors having additive effects on reaction time in one experiment will also have additive effects in another experiment done in the same way, but with different error rates. These results can be used to augment an analysis of reaction time with an analysis of accuracy; further, experiments measuring accuracy alone can be analysed. The procedure is illustrated with three experiments reported in the literature: a choice task, a lexical decision task, and a memory-scanning task. Speed and accuracy for processes in critical path networks are also discussed. The rate of change of log percent correct with respect to time can be represented as a conservative flow in such networks.
