Abstract: Judgment of learning is an important form of metamemory monitoring judgment, which is a predictability judgment of the recollect in the later recall test done by the individuals after learning. As for JOL, how to improve the accuracy of JOL makes one of the core contents of the JOL study. There are many factors which effect JOL and the accuracy of JOL, including the intrinsic clues, the extrinsic clues, the mnemonics clues. Among these, certain learning conditions, such as spaced learning and test, are extrinsic factors which can be manipulated easily. They can make a critical impact on the memory and metamemory. The study included two experiment designs in order to improve memory effect and metamemory monitoring accuracy. Experiment 1 took the form of two-factor mixed design; investigate the effect of spaced learning made on JOL and the accuracy of JOL, massed learning as a reference. Experiment 2 was a two-factor mixed design. Based on the spaced learning effect in experiment 1, experiment 2 pulled in test effect and explored how spaced learning with test impact the judge of learning and the accuracy of JOL. The results showed that, a) The spaced learning improved recall performance significantly, reduced the over confidence in immediate judgment of learning and improve the accuracy of JOL for hard items. b) Testing before repetitive learning could enhance memory traces and significantly improve the relative accuracy of JOL on the base of spaced learning. c) Different extrinsic clues should be distinguished; spaced learning and pre-test were different extrinsic clues.
