Two and eight choice recognition memory was compared in a group of normal individuals shortly after learning a list of words and seven days later. In addition to selecting the correct response, subjects were required to indicate the confidence of their choices. The results showed that eight choice recognition performance was differentially worse than two choice recognition at delayed compared to immediate test. These results were similar to some reported by Miller (1977) in which he compared recognition in dementing amnesics and controls at immediate test. While Miller interpreted his data in terms of a selective retrieval deficit in amnesics, our data suggests that both sets of results arise because Signal Detection Theory is applicable to recognition memory data. An additional result was that subjects felt they guessed correctly selected words more frequently after a delay.
在一组正常个体学习单词列表后不久以及七天后，对二选一和八选一的再认记忆进行了比较。除了选择正确答案外，受试者还被要求表明他们选择的信心。结果显示，与即时测试相比，在延迟测试时，八选一的再认表现比二选一的再认表现差异更大。这些结果与米勒（1977年）报告的一些结果相似，他在即时测试中比较了痴呆性失忆症患者和对照组的再认情况。虽然米勒根据失忆症患者的选择性检索缺陷来解释他的数据，但我们的数据表明，两组结果的出现都是因为信号检测理论适用于再认记忆数据。另一个结果是，受试者觉得他们在延迟后猜对正确选择单词的频率更高。
