Metacognitive judgments and disfluency - Does disfluency lead to more accurate judgments, better control, and better performance?

Theories of metacognition assume that better monitoring leads to better control and performance. Furthermore, monitoring accuracy is often low because students are overconfident (absolute accuracy) and unable to discriminate comprehension of different text-passages (relative accuracy). Fluency seems to be a cue for metacognitive judgments, and therefore, reducing fluency should lead to less automatic processing, lower judgments, and better absolute and relative accuracy. Because the accuracy of metacognitive judgments is the basis of the control of learning, disfluency should lead to more appropriate control and thus to better performance. To test these assumptions, students (N = 83) learned either with disfluent or with fluent text-passages. The results show that disfluency led to better absolute and relative accuracy but not for all types of judgments. Moreover, students hardly implemented monitoring in control, resulting in lack of improved performance. Further research is required to investigate why students did not base control on monitoring.
