Abstract: The relationship between judgments of learning and allocation of study time is an important issue in the study of metacognition. Studies on JOLs aims at revealing one’s own learning and memory activities in order to control the learning process effectively and allocate the study time reasonably, which is a typical example showing that metacognitive monitoring affects control processes. However, some researchers have found that the allocation of study time actually serves a dual function: It subserves a monitoring function as well as a control function. Therefore, based on its dual function, some studies on JOLs and the allocation of study time were reviewed, the relation models between them—— the MC Model (monitoring affects control hypothesis) and the CM Model (control affects monitoring hypothesis) were introduced in this paper; then two combinational dynamic models in which MC model and CM model interrelate and interact with each other were also discussed. Finally, the limitations of these models and new directions in future studies were proposed.

Key words: judgments of learning, allocation of study time, monitoring, control
