Null and void? Errors in meta-analysis on perceptual disfluency and recommendations to improve meta-analytical reproducibility

Weissgerber (2021) · Educational Psychology Review · Read the paper

Weissgerber, Brunmair and Rummer examine an earlier meta-analysis on null effects of perceptual disfluency on learning outcomes in a text-based educational context. They identify errors and inconsistencies in the coding and in the reported effect sizes, while noting that from a technical standpoint it meets current meta-analytic guidelines. They discuss transparency and open-science practice in creating and reporting meta-analyses and offer recommendations to improve them.
