延迟学习判断的时间加工进程

学习判断是指人们在学习之后对自己学习效果所做的一种预测,是元记忆监测性判断的一种形式。学习判断按其发生时间的不同可以分为即时学习判断和延迟学习判断。与即时学习判断相比,延迟学习判断的相对准确性较高,被称为延迟学习判断效应。实验借助事件相关电位技术探究延迟学习判断的时间加工进程,发现高等级学习判断比低等级学习判断诱发了更大的时间窗为400-600ms的早期新旧效应和800-1200ms的晚期右侧额区新旧效应。上述结果表明,延迟学习判断包含不止一个加工过程,早期新旧效应反映了线索再认的过程,晚期右侧额区效应则反映了对提取之后的评估过程,该结果进一步验证了两阶段模型解释延迟学习判断效应的有效性。

Time Course of Delayed Judgments of Learning

As a form of metamemory monitoring,judgments of learning(JOLs)are predictions of the likelihoods of remembering previous learned materials on a future test.Previous studies found that the relative accuracy was higher for delayed JOLs than immediate JOLs,which is called the delayed-JOL effect.The current study investigated the time course of delayed JOLs by adopted Event-Related Potentials(ERPs)technique.The results showed that there were significant differences between high JOLs and low JOLs in the time windows from 400 to 600ms and from 800 to 1200ms.The early old/new effect(400-600ms)reflected the recognition of the cue,and the late old/new effect(800-1200ms)at right mid-frontal area reflected evaluation stage behind the retrieval.The current study firstly provided ERPs evidence of the two stages model of delayed JOLs.
