本文源于人类记忆的复合轨迹分布式模型，特别是复合全息联想回忆记忆（CHARM）模型中的一个技术问题。简而言之，复合跟踪——在这些模型中用作中心构造——可能会灾难性地失去控制。为了解决这个问题，需要实现一个存储前新奇度-熟悉度监测器和一个简单的控制程序。八行实验证据都集中在这样一个观点上，即这种新奇熟悉度监测的输出是人们对认知感觉的元认知判断的基础。监测-控制机制的崩溃在模型中产生了korsakoff样症状。因此，科萨科夫失忆症的两大特征——感知判断的缺陷和无法从主动抑制中解脱出来——被归因于监测控制的失败，而不是基本记忆系统的缺陷。
This article stems from a technical problem in composite-trace distributed models of human memory and particularly in the Composite Holographic Associative Recall Memory (CHARM) model. Briefly, the composite trace--used as a central construct in such models--can become catastrophically out of control. To solve the problem, a prestorage novelty-familiarity monitor and a simple control procedure need to be implemented. Eight lines of experimental evidence converge on the idea that output from such a novelty-familiarity monitor underlies people's metacognitive judgments of feeling of knowing. Breakdown of the monitoring-control mechanism produces Korsakoff-like symptoms in the model. Impairments in feeling-of-knowing judgments and the failure to release from proactive inhibition, both characteristic of Korsakoff amnesia, are thus attributed to a monitoring-control failure rather than to deficits in the basic memory system.
