记忆监测的相对准确性是元记忆研究中一个重要内容。研究者采用了各种方法来测量人们记忆监测的判断值对正确项目和错误项目的区分度,例如相关法、信号检测论(SDT)测量法。其中,gamma相关从1984年起一直被广泛用于记忆监测相对准确性的测量。基于SDT的新指标da弥补了gamma相关在实际应用中的不足,并引发了新的研究兴趣。文章对da的提出背景、计算方法和应用前景进行了详细的介绍,对da与其他常用方法在使用中的优势进行了比较。对da的具体应用进行了说明,同时指出了da的使用条件。

This article described a revised index of relative metamnemonic accuracy (also known as resolution) for research on metacognitive monitoring. A number of different indices have served in the measure of metamnemonic accuracy,such as Goodman-Kruskal gamma coefficient (γ) and indices of the signal detection theory (SDT) . SDT indices d' have their own limitation when applied to relative metamnemonic accuracy. In contrast,gamma coefficient has dominated in metamnemonic research since Nelson (1984) introduced it. Even though researchers found some of its crucial shortcomings,no index could evaluate the resolution of metamnemonic judgments better than γ. However,a revised SDT index da may serve as a desirable replacement of γ. da has a larger scale of [0,∞ ) than [-1,1]of γ ,and it can overcome the shortcomings of γwith respect to interval-level analyses and conclusions. A couple of studies focused on the use of this new index to evaluate metamnemonicresolution (Benjamin Diaz,2008; Masson Rotello,2009) . We explained the advantages of da in terms of its application in research,and,instead of providing mathematical and statistical accounts,and went on to compute da ,using the example from Benjamin and Diaz (2008) . Based on those empirical comparisons of da and γ,we made a recommendation that da would be the most desirable index of relative metamnemonic accuracy in a 2 × N (N ≥ 4) metacognitive task. da has been adopted in several studies on recognition as an index of discrimination (Benjamin,Diaz, Wee,2009; Macmillan Creelman,2004; Matzen Benjamin,2009; Tullis Benjamin,2011) ,and recently,Benjamin and his colleague investigated metamnemonic accuracy for faces with da for the first time (Hourihan,Benjamin, Liu,2012) . Therefore,we concluded that da has a hopeful prospect in its application in research on metacognitive monitoring,and we suggested that researchers should develop a standardized procedure as well as an advanced program for data processing to make da widely accepted by metacognitive researchers.
