We develop and discuss four criteria for evaluating the appropriateness of units of analysis for task-analytic research and suggest potential alternatives to the units of analysis currently used. Of the six solutions discussed, the most commonly used unit of analysis in current behavior analytic work, percentage correct, meets only one of the four criteria. Five alternative units of analysis are presented and evaluated: (a) percentage of opportunities to perform meeting criterion, (b) trials to criteria, (c) cumulative competent performances, (d) percentage correct with competent performance coded, and (e) percentage correct with competent performance coded and a grid showing performance on individual steps of the task analysis. Of the solutions evaluated, only one--percentage correct with competent performance coded and a task analysis grid--met all four criteria.
我们制定并讨论了四条标准，用于评估任务分析研究中分析单位的适当性，并提出了当前所使用分析单位的潜在替代方案。在讨论的六种解决方案中，当前行为分析工作中最常用的分析单位——正确百分比，仅符合四条标准中的一条。文中提出并评估了五种替代分析单位：（a）达到标准的执行机会百分比，（b）达到标准所需的试验次数，（c）累积胜任表现，（d）对胜任表现进行编码后的正确百分比，以及（e）对胜任表现进行编码后的正确百分比和一个显示任务分析各个步骤表现的网格。在评估的解决方案中，只有一种——对胜任表现进行编码后的正确百分比和一个任务分析网格——符合所有四条标准。
