“…For this reason, if students base metacognitive evaluations of their learning on how fluently or easily they processed learning materials-but that experience of fluency is not correlated with their actual learning-then their self-assessments of their learning will be inaccurate. For example, much research has examined the effect of perceptual fluency on participants' memory judgments and demonstrated that physically increasing the fluency of item processing (e.g., making the font of text materials larger or easier to read) affects memory judgments without affecting memory performance: participants tend to judge the more-fluent items (i.e., large-font items) as being more memorable than the less-fluent items (i.e., small-font items), even though memory is not affected by such font-size manipulations (e.g., Magreehan, Serra, Schwartz, & Narciss, 2016;Mueller, Dunlosky, Tauber, & Rhodes, 2014;Rhodes & Castel, 2008).…”
