Metamemory is a multifaceted concept, which deals with the individual's knowledge and control of his or her own memory system. One metacognitive ability that has considerable importance in everyday life is the ability to control his or her own memory. In this study, we have examined whether Parkinson's disease affects the degree to which a person allocate study time. 17 Parkinson subjects and 18 older controls participated in this study. Parkinson subjects and control subjects made a readiness recall task in which subjects monitor themselves the learning procedure, allowing to measure metamemory control (study time by item). Control subjects were found to take more time in study than parkinson subjects. The lists were learned under two condition: a self-paced condition in which subjects could study each word as long as they would and an experimenter-paced condition. The analysis revealed that control subjects recalled more items than parkinson subjects only in the self-paced condition. These results suggested that Parkinson-related differences in the allocation of study time mediate a part of Parkinson-related differences in memory performance.
元记忆是一个多方面的概念，它涉及个体对自身记忆系统的知识和控制。在日常生活中具有相当重要性的一种元认知能力是控制自己记忆的能力。在本研究中，我们考察了帕金森病是否会影响一个人分配学习时间的程度。17名帕金森病患者和18名老年对照者参与了本研究。帕金森病患者和对照者完成了一项准备回忆任务，在该任务中，受试者自行监控学习过程，从而能够测量元记忆控制（按项目计算的学习时间）。结果发现，对照者在学习上花费的时间比帕金森病患者更多。这些列表是在两种条件下学习的：一种是自定进度条件，即受试者可以根据自己的意愿学习每个单词；另一种是实验者设定进度的条件。分析表明，只有在自定进度条件下，对照者比帕金森病患者回忆出的项目更多。这些结果表明，帕金森病相关的学习时间分配差异介导了帕金森病相关的记忆表现差异的一部分。
