The ability to monitor memory performance has considerable importance in everyday life and is among the proposed metamemory dimensions which has been widely investigated. The ability to monitor memory performance accurately was examined in 16 patients with schizophrenia and 16 control subjects by using a Feeling-of-Knowing task on episodic information. Feeling-of-Knowing judgments are predictions made about the likelihood of subsequent recognition of currently non-recallable information. Participants were given cued recall and recognition tests of 50 sentence-target words. Feeling-of-knowing judgments were made for non-recalled targets. Our results first confirm that schizophrenia is associated with episodic memory impairment. By using the Feeling-of-Knowing task, patients with schizophrenia were found to predict accurately their subsequent recognition performance, suggesting an interesting dissociation between a preserved metamemory and an altered memory.
监测记忆表现的能力在日常生活中具有相当重要的意义，并且是已被广泛研究的拟议元记忆维度之一。通过使用关于情景信息的知晓感任务，对16名精神分裂症患者和16名对照受试者的记忆表现监测能力进行了检验。知晓感判断是对当前无法回忆的信息随后被识别的可能性所做的预测。参与者接受了50个句子目标词的线索回忆和识别测试。对未回忆出的目标进行知晓感判断。我们的结果首先证实，精神分裂症与情景记忆损害有关。通过使用知晓感任务，发现精神分裂症患者能够准确预测他们随后的识别表现，这表明在保存的元记忆和改变的记忆之间存在一种有趣的分离。
