患者Y.R.，海马损伤导致记忆中断，但不影响熟悉性，在用类似的箔纸进行的是/否（YN）物体识别记忆测试中受损。然而，她在将目标与相应的类似箔配对的强制选择对应（FCC）版本的测试中没有受损（Holdstock等人，2002年）。这种分离是由互补学习系统（CLS）的神经网络模型（诺曼和奥莱利，2003年），如果回忆受损，但熟悉的是保留。CLS模型还预测，完全依赖于熟悉的参与者应该在强迫选择非对应（FCNC）测试中受损，其中目标与其他目标类似。本研究测试这些预测的所有三个测试格式（YN，FCC，FCNC）在正常参与者使用两种变体的记住/知道程序。正如预测的那样，在YN和FCNC测试中，单独使用熟悉度的表现明显比标准识别差，但在FCC测试中则不然。以召回到拒绝的形式进行的召回是驱动YN识别的主要过程。这增加了对患者数据的解释的支持，根据患者数据，海马损伤导致回忆缺陷，导致YN测试相对于FCC的表现不佳。
Patient Y.R., who suffered hippocampal damage that disrupted recollection but not familiarity, was impaired on a yes/no (YN) object recognition memory test with similar foils. However, she was not impaired on a forced-choice corresponding (FCC) version of the test that paired targets with corresponding similar foils (Holdstock et al., 2002). This dissociation is explained by the Complementary Learning Systems (CLS) neural-network model (Norman & O'Reilly, 2003) if recollection is impaired but familiarity is preserved. The CLS model also predicts that participants relying exclusively on familiarity should be impaired on forced-choice noncorresponding (FCNC) tests, where targets are presented with foils similar to other targets. The present study tests these predictions for all three test formats (YN, FCC, FCNC) in normal participants using two variants of the remember/know procedure. As predicted, performance using familiarity alone was significantly worse than standard recognition on the YN and FCNC tests, but not on the FCC test. Recollection in the form of recall-to-reject was the major process driving YN recognition. This adds support to the interpretation of patient data, according to which hippocampal damage causes a recollection deficit that leads to poor performance on the YN test relative to FCC.
