基本利率和收益对评级接收器操作特征曲线形状的影响与信号检测理论（SDT）的基本假设不一致，特别是转移决策准则的概念。Mueller和Weidemann（2008）提出，这些意外的现象不是由于决策标准结构的问题，而是由于两个复合效应：决策标准在试验中的不稳定性，以及决定将报告哪个置信等级的侧翼标准的更大不稳定性。作者的决策噪音假设存在几个问题。首先，即使他们关于决策噪音的假设被认为是理所当然的，拒绝SDT模型的评级数据的关键特征仍然是一个谜。第二，当反应时间取代信心作为分析的基础时，在评级范式中表现出的SDT的相同违规行为也表现在是非检测任务中。最后，决策噪声假设预测，敏感性将增加时，这种变化的一个来源，在以前的试验的反应，是控制为这一预测是一贯违反的是-否和评级条件的Mueller和Weidemann实验。在附录中，我们回应了Weidemann和Mueller（2008）对本评论的回复。
The effects of base rates and payoffs on the shapes of rating receiver operating characteristic curves are inconsistent with the basic assumptions of signal detection theory (SDT), in particular the notion of a shifting decision criterion. Mueller and Weidemann (2008) propose that these unexpected phenomena are not due to problems with the decision-criterion construct but are instead due to two compounded effects: instability of the decision criterion across trials, and even greater instability in the flanking criteria that determine which confidence rating will be reported. There are several problems with the authors' decision-noise hypothesis. First, even if their hypothesis about decision noise were taken for granted, the key feature of the ratings data that rejects the SDT model would remain a mystery. Second, the same violations of SDT that are exhibited in the ratings paradigm are also exhibited in the yes-no detection task when response time is substituted for confidence as a basis for analysis. Finally, the decision-noise hypothesis predicts that sensitivity will increase when one source of this variation-the response on a previous trial-is controlled for This prediction was consistently violated in both the yes-no and ratings conditions of Mueller and Weidemann experiment. In an Addendum, we respond to Weidemann and Mueller (2008) reply to this Comment.
