最近的报告表明，一些失忆症患者在强迫选择识别记忆测试中表现相对正常。他们保留的表现可能反映了这样一个事实，即测试更依赖于对熟悉程度的评估，这是一个相对保留在这些患者身上的过程，而不是其他识别测试，如是-否测试，可能更多地依赖于回忆。目前的研究在对照组和健忘症患者中使用是-否和强迫选择程序来检查识别记忆，以确定这两个任务是否不同地依赖于回忆和熟悉，以及健忘症患者中观察到的识别记忆缺陷的程度是否取决于用于测量表现的识别测试的类型。在健康受试者中使用记忆-知道程序的结果表明，在识别准确性和回忆对这两个任务的贡献方面没有实质性差异。此外，失忆症患者在强迫选择测试中的表现并不比在是-否测试中的表现更好，这表明熟悉程度对这两种类型的识别测试的贡献是相同的。(C) 2000 Elsevier Science Ltd.版权所有。
Recent reports suggest that some amnesic patients perform relatively normally on forced-choice recognition memory tests. Their preserved performance may reflect the fact that the test relies more heavily on assessments of familiarity, a process that is relatively preserved in these patients, than do other recognition tests such as yes-no tests, which may rely more on recollection. The current study examined recognition memory using yes-no and forced-choice procedures in control and amnesic patients in order to determine whether the two tasks differentially relied on recollection and familiarity, and whether the extent of the recognition memory deficit observed in amnesia was dependent upon the type of recognition test used to measure performance. Results using the remember-know procedure with healthy subjects showed that there were no substantial differences in recognition accuracy or in the contribution of recollection to these two tasks. Moreover, amnesic patients were not found to perform better on a forced-choice test than on a yes-no test, suggesting that familiarity contributed equally to these two types of recognition test.
