在实验1中，使用记住/知道范式与控制参与者，我们比较了回忆和熟悉的复合刺激和不相关的词对联想识别的贡献。结果表明，熟悉性对复合刺激的联想识别的贡献大于对无关词对的联想识别。在实验2中，我们研究了联想识别记忆内侧颞叶健忘症，间脑健忘症，并在实验1中采用的刺激控制参与者。而联想识别的化合物和无关的话几乎是相同的控制参与者，联想识别的化合物比无关的词对健忘症患者。这种模式在内侧颞叶健忘症组和间脑健忘症组中都有观察到。这些结果表明，在记忆缺失症的联想识别增强的程度上，性能可以支持学习诱导熟悉的研究对。(c)2006爱思唯尔有限公司保留所有权利。
In Experiment 1, using the remember/know paradigm with control participants, we compared the contribution of recollection and familiarity to associative recognition for compound stimuli and for unrelated word pairs. It was demonstrated that familiarity makes a greater contribution to associative recognition of compound stimuli than to associative recognition of unrelated word pairs. In Experiment 2, we examined associative recognition memory in medial temporal lobe amnesics, diencephalic amnesics, and control participants for the stimuli employed in Experiment 1. Whereas associative recognition for compounds and unrelated words was nearly identical in control participants, associative recognition was higher for compounds than for unrelated word pairs in amnesic patients. This pattern was observed in the medial temporal amnesic group as well as in the diencephalic amnesic group. These results suggest that associative recognition in amnesia is enhanced to the extent that performance can be supported by study-induced familiarity for the studied pair. (c) 2006 Elsevier Ltd.
