Many theories of memory predict that the slope of the z-transformed receiver-operating characteristic (ROC) curve should decrease with increases in the memory strength of old items. While several prior studies have failed to demonstrate this effect, the results of two experiments demonstrate that increasing presentation duration can reduce the slope of the z-transformed ROC curve. These results raise questions about the generality of prior results and of dual-process theories designed to accommodate those results. We close by emphasizing that determining the experimental circumstances that affect whether or not the slope of the z-transformed ROC curve decreases will provide important constraints on theories of recognition memory.
许多记忆理论预测，z变换后的接收者操作特征（ROC）曲线的斜率应随着旧项目记忆强度的增加而减小。虽然之前的几项研究未能证明这种效应，但两项实验的结果表明，增加呈现持续时间可以降低z变换后的ROC曲线的斜率。这些结果对先前结果的普遍性以及旨在适应这些结果的双过程理论提出了质疑。我们最后强调，确定影响z变换后的ROC曲线斜率是否会减小的实验情况，将为识别记忆理论提供重要的限制条件。
