关于顺行性健忘症对记忆和熟悉性的影响，先前使用加工分离和记忆-知道程序的研究得出了相互矛盾的结论。我们认为，这些明显的矛盾之所以出现，是因为不同的模型被用来解释结果，而且不同组之间的错误警报率的差异偏向于那些模型提供的估计。使用包含反应偏差的双过程信号检测模型对这些研究进行重新分析后发现，健忘症导致记忆显著减少，熟悉程度略有下降，但持续下降。为了检验模型的假设，并进一步评估遗忘症患者的认知缺陷，我们研究了遗忘症患者和对照患者的受试者操作特征(ROC)。对照组的ROC呈弧形且不对称，而健忘组ROC呈弧形且对称。结果支持了该模型的预测，并表明健忘症与记忆和熟悉性方面的缺陷有关。
Previous studies using the process dissociation and the remember-know procedures led to conflicting conclusions regarding the effects of anterograde amnesia on recollection and familiarity. We argue that these apparent contradictions arose because different models were used to interpret the results and because differences in false alarm rates between groups biased the estimates provided by those models. A reanalysis of those studies with a dual-process signal-detection model that incorporates response bias revealed that amnesia led to a pronounced reduction in recollection and smaller but consistent reduction in familiarity. To test the assumptions of the model and to further assess recognition deficits in amnesics, we examined receiver operating characteristics (ROCs) in amnesics and controls. The ROCs of the controls were curved and asymmetrical, whereas those of the amnesics were curved and symmetrical. The results supported the predictions of the model and indicated that amnesia was associated with deficits in both recollection and familiarity.
