元理解监控的精确性及其延迟关键词效应

Accuracy of Metacomprehension Monitoring and Delayed-Keyword Effect

元理解监控的精确性是指元理解判断与标准测验间的一致程度，通常用二者的Gamma系数作为其指标。梳理近20年元理解监控的研究发现个体元理解监控的精确性并没有想象的那么高。读完文章后延迟写出关键词可以显著提高元理解监控的精确性，这被称为元理解监控的延迟关键词效应，时间上的延迟与延迟时间内主动的认知加工是这一效应得以发生的机制。最后，在分析批评已有研究的基础上提出扩展的元理解监控延迟效应假设。

A person's metacomprehension monitoring accuracy is operationalized as the intra-individual correlation between a person's comprehension ratings and his or her test performance， the metacomprehension accuracy and its effect are key issues in the study of metacomprehension and become one of the most intensely investigated of the metacognitive judgments. In this paper， we started with a review on the study of the methodolody for research on metacomprehension judgment and its accuracy. Then， the delayed-keyword effect of metacomprehension monitoring and its mechanism were introduced and discussed. Finally， the limitations of previous studies and some suggestions and new directions were proposed on the research of metacomprehension monitoring accuracy.
