Nine amnesic patients of mixed aetiology were studied in a duration-judgement task that allowed three measures of memory to be obtained. On each trial of the task, subjects attempted to read a briefly flashed word and to estimate the duration of the flash. Both word identification and duration estimation differed as a function of prior study. Words that were previously studied were identified more often and were estimated to have been flashed for a longer duration than were words not previously studied. These priming effects were found in young subjects in Experiment 1 and in amnesic patients and age-matched control subjects in Experiment 2. Priming effects were normal in the amnesic patients, whereas these patients were severely impaired at recognizing the same words. Previous results have also shown that amnesic patients can perform normally on certain memory tests, including priming of word identification. These results show that priming of duration judgements can also be included in the category of indirect measures of memory that are spared in amnesia.
对9名病因各异的失忆症患者进行了一项时长判断任务的研究，该任务可获取三种记忆测量指标。在任务的每次试验中，受试者尝试阅读一个短暂闪现的单词并估计闪现的时长。单词识别和时长估计均因先前的学习情况而有所不同。与未先前学习过的单词相比，先前学习过的单词被识别的频率更高，且估计闪现的时长更长。在实验1的年轻受试者以及实验2的失忆症患者和年龄匹配的对照受试者中均发现了这些启动效应。失忆症患者的启动效应正常，而这些患者在识别相同单词方面严重受损。先前的研究结果还表明，失忆症患者在某些记忆测试中可以正常表现，包括单词识别的启动。这些结果表明，时长判断的启动也可归入失忆症中未受影响的间接记忆测量类别。
