Although reaction time measures have been used extensively in many types of between-group comparisons, the assumptions and limitations of reaction time measurement are not always recognized. In this article we discuss three issues that should be considered when designing and interpreting comparisons involving reaction time. These concern speed-accuracy tradeoffs, methods of analyzing measures postulated to reflect specific processes, and methods for distinguishing group-related influences that are shared with other variables from those that are unique to a single variable.
尽管反应时间测量已广泛应用于多种组间比较中，但反应时间测量的假设和局限性并非总能得到认识。在本文中，我们讨论在设计和解释涉及反应时间的比较时应考虑的三个问题。这些问题涉及速度-准确性权衡、分析假定反映特定过程的测量方法，以及区分与其他变量共有的组相关影响和单个变量特有的影响的方法。
