As one of prospective monitories, JOL is an important aspect of meta-memory monitoring and control which reflects predictions of one’s memory. By research of JOL, we can investigate individuals learning and memory about the understanding of the effect degree, as to have a better control on their own learning and memory process. The study of JOL is very valuable and useful as it can provide theoretical base to individuals of more effective learning and memory. Based on the Koriat’s cues model theory, our investigation focus on the differences between the two learning conditions which the immediate judgment of learning and the delayed judgment of learning, and on the effect of intrinsic cues and extrinsic cues on them. We also have a further explore on their different thread on the effect of JOL. The subjects are 39 undergraduate students of Shaanxi Normal University, China. Experiment using a 2 × 2 × 2 3-factor mixed design. Intrinsic cues mean word types, extrinsic cues means presentation time and order. The experiment consists of two parts immediate judgment of learning and delayed judgment of learning where each subject must participate. The results showed that: (1) the relative accuracy of delayed JOL is significantly higher than the immediate JOL. (2) Different types of cues have different effects on JOL, JOL more sensitive to the intrinsic cues. (3) The same type cue has different influence on various JOL conditions. (4) In the immediate condition, the distribution of JOL emerges a gradually rising trend; furthermore, it shows a distribution of the "U" curve in the delayed condition.
