... Research on memory and metamemory indicates that differences in font size create a metacognitive illusion: While people think that larger headlines are more memorable than smaller headlines, actual memorability is similar for smaller and larger headlines. In the first laboratory study to investigate the effect of font size on predictions of future memory performance (judgments of learning, or JOLs), Rhodes and Castel (2008) found higher JOLs for words presented in a larger font than for words presented in a smaller font, even though font size did not influence memory performance (for exceptions, see Price, McElroy, & Martin, 2016;Undorf, Söllner, & Bröder, 2018). Meanwhile, a number of subsequent studies replicated this font size effect (e.g., Hu, Liu, Li, & Luo, 2016;Kornell, Rhodes, Castel, & Tauber, 2011;McDonough & Gallo, 2012;Miele, Finn, & Molden, 2011;Mueller, Dunlosky, Tauber, & Rhodes, 2014;Price & Harrison, 2017;Susser, Mulligan, & Besken, 2013;Undorf et al., 2018). ...
