Abstract
Presenting information in a perceptually degraded format sometimes enhances learning outcomes. However, earlier studies in which words were presented in large or small fonts in a paradigm that also involved item-by-item judgments of learning (JOLs) consistently yielded no mnemonic benefit of small fonts. Can small font size enhance memory under hitherto unexamined conditions? A series of 11 experiments was conducted to examine systematically the effect of font size on memory for words and whether it depends on the strength of the font size manipulation, whether JOLs are solicited, the format of the test, and study time. The resulting data were meta-analyzed. Results yielded a u-shape relationship between font size and memory. Compared to intermediate fonts, there was a memory advantage for words presented in large fonts but also for words presented in very small fonts. However, the requirement to provide a JOL moderated the benefit of the very small font, which was eliminated when JOLs were solicited. Test format and study time did not moderate the effect of font size on memory. JOLs were insensitive to the u-shape relationship and consistently increased with font size. These findings provide support for the notion that perceptually degraded materials can enhance learning outcomes, but also highlight the importance of systematic investigation of moderators. The results shed new light on the inconsistent effects of manipulations of perceptual degradation on learning outcomes observed in earlier studies.
