进行了三个实验，以确定由信号检测理论定义的五个反应偏差指数（β，C，B“，B-H”和B-D“）中的哪一个提供了观察者在警戒任务中反应意愿的最有效测量。结果表明，传统的参数偏差指数β是一个不充分的措施，在各个方面的反应偏差，而新的参数措施c是最有效的所有五个指标。当三个非参数指标（B“、B-H”和B-D“）分别进行检查时，B-D”成为最有效的非参数指标。我们建议警戒研究人员在涉及参数模型时使用c而不是beta来测量偏倚，在使用非参数模型时使用B-D“而不是B ''和B-H'。
Three experiments were conducted to determine which of five response bias indices (beta, c, B'', B-H', and B-D'') defined by the theory of signal detection provides the most effective measure of the observer's willingness to respond in a vigilance task. The results indicated that the traditional parametric bias index beta was an inadequate measure of response bias in every respect, whereas the newer parametric measure c was the most effective of all five indices. When the three nonparametric measures (B'', B-H', and B-D'') were examined separately, B-D'' emerged as the most effective nonparametric index. We recommend that vigilance researchers use c rather than beta to measure bias when a parametric model is involved and B-D'' instead of B'' and B-H' when a nonparametric model is used.
