Abstract: Metacognitive monitoring and control is not only affected by the mastery degree of people's learning and memory, but also by social cues. In the present study, the effects of mastery degree and social cues on metacognitive monitoring (Experiment 1) and control (Experiment 2) were investigated. The mastery degree was based on whether the answer is correct or not, and the social cues provided the choice of "most people". The results show:Firstly, mastery degree and social cues independently influence metacognitive monitoring. Specifically, the higher the degree of mastery, the higher the level of confidence; Confidence levels are higher when individual choices are consistent with social cues. Secondly, the degree of mastery and social clues jointly influence metacognitive control. In particular, the higher the degree of mastery, the more individuals tend to stick to their initial choices. When the social cues are consistent with the initial choice of individuals, individuals tend to stick to their initial choice. Individuals tend to change their initial choices when they have a low level of mastery, and the social cues are inconsistent with individuals, they tend to be consistent with the majority of people. When the degree of mastery is low and the social clues are inconsistent with the individual, they tend to change their initial choice to be consistent with most people.

Key words: mastery degree, social cues, metacognitive monitoring and control
