参与者研究了呈现不同短暂持续时间的自然主义图片，然后接受了一项识别测试，在测试中他们指出了每一张图片是旧的还是新的，并对他们的信心进行了评级。在一项实验中，他们指出了每一种“旧的”/“新的”反应是基于对图片中特定特征的记忆，还是基于图片的总体熟悉度；在另一项实验中，我们定义了倾向于引发特征反应与熟悉性反应的图片。因此，特征/熟悉度在一个实验中是因变量，在另一个实验中是自变量。在这两个实验中，基于特征的反应比基于熟悉的反应更准确，两种类型的反应的信心和准确性都随着持续时间的延长而增加。然而，当信心被控制时，基于熟悉度的平均准确率高于基于特征的反应。其理论含义是，信心和准确性源于不同的潜在信息。应用的含义是，当内存报告的现象基础不同时，不应将置信度差异视为暗示准确性差异。(保留所有权利。
Participants studied naturalistic pictures presented for varying brief durations and then received a recognition test on which they indicated whether each picture was old or new and rated their confidence. In 1 experiment they indicated whether each “old”/“new” response was based on memory for a specific feature in the picture or instead on the picture's general familiarity; in another experiment, we defined pictures that tended to elicit feature versus familiarity responses. Thus, feature/familiarity was a dependent variable in 1 experiment and an independent variable in the other. In both experiments feature-based responses were more accurate than those that were familiarity based, and confidence and accuracy increased with duration for both response types. However, when confidence was controlled for, mean accuracy was higher for familiarity-based than for feature-based responses. The theoretical implication is that confidence and accuracy arise from different underlying information. The applied implication is that confidence differences should not be taken as implying accuracy differences when the phenomenal basis of the memory reports differ.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
