Evidence is presented that recognition judgments are based on an assessment of familiarity, as is described by signal detection theory, but that a separate recollection process also contributes to performance. In 3 receiver-operating characteristics (ROC) experiments, the process dissociation procedure was used to examine the contribution of these processes to recognition memory. In Experiments 1 and 2, reducing the length of the study list increased the intercept (d') but decreased the slope of the ROC and increased the probability of recollection but left familiarity relatively unaffected. In Experiment 3, increasing study time increased the intercept but left the slope of the ROC unaffected and increased both recollection and familiarity. In all 3 experiments, judgments based on familiarity produced a symmetrical ROC (slope = 1), but recollection introduced a skew such that the slope of the ROC decreased.
有证据表明，识别判断是基于对熟悉度的评估，正如信号检测理论所描述的那样，但一个独立的回忆过程也对表现有贡献。在3个接收者操作特征（ROC）实验中，采用过程分离程序来检验这些过程对识别记忆的贡献。在实验1和实验2中，缩短学习列表的长度增加了截距（d'），但降低了ROC的斜率，并增加了回忆的概率，但对熟悉度影响相对较小。在实验3中，增加学习时间增加了截距，但未影响ROC的斜率，同时增加了回忆和熟悉度。在所有3个实验中，基于熟悉度的判断产生了对称的ROC（斜率 = 1），但回忆引入了一种偏差，使得ROC的斜率降低。
