Subclaims¶

q3 i2 In studies with expository texts, sentence unscrambling yielded significantly stronger generation effects (g = 0.77) than letter completion (g = 0.23), while in narrative texts letter completion descriptively outperformed sentence unscrambling (g = 0.57 vs. 0.36, not significant). → Julia Schindler · Tobias Richter 2023

Subset moderator analyses within the three-level meta-analysis, examining generation task separately for expository and narrative texts. The article reports the expository-text contrast as significant and the narrative-text contrast (letter completion g = 0.57 vs. sentence unscrambling g = 0.36) as descriptively stronger but not significant.

"In studies based on expository texts, sentence unscrambling tasks yielded stronger generation effects (g = 0.77, p < 0.001) than letter completion tasks (g = 0.23, p = 0.006), and this difference was significant, Q M (df = 1) = 6.44, p = 0.011, k = 57."
