We describe a procedure for differentiating among potential precursor responses for use in a functional analysis. Conditional probability analysis of descriptive assessment data identified three potential precursors. Results from the indirect assessment corresponded with those obtained from the descriptive assessment. The top-ranked response identified as a precursor according to the indirect assessment had the strongest relation according to the probability analysis. When contingencies were arranged for the precursor in a functional analysis, the same function was identified as for target behavior, supporting the utility of indirect and descriptive methods to identify precursor behavior empirically.
我们描述了一种用于区分潜在前导反应的方法，以便在功能分析中使用。描述性评估数据的条件概率分析确定了三个潜在的前导反应。间接评估的结果与描述性评估的结果相符。根据间接评估确定为前导反应的排名最高的反应根据概率分析具有最强的关系。当在前导反应的功能分析中安排了条件作用时，与目标行为相同的功能被识别出来，这支持了间接和描述性方法在经验上识别前导行为的有效性。
