Subclaims¶

q2 i? In an exploratory univariate moderator analysis, retrieval interval (less than one day versus more) neared significance (β=0.626, SE=0.162, p=.058); restricting to intervals over one day gave g = 0.378 with a CI still crossing zero. → Murray 2023

q2 · i? · quant-synthesis · r2

Exploratory moderator analysis within the retrieval subset, reported as nearing but not reaching significance. The authors report the restricted weighted mean as "g = 0.378 (se 0.108) (95% confidence interval [-0.013, 0.768])".

"one factor that neared significance despite our small sample size was retrieval interval, which was coded as a univariate variable: less than one day or more than one day ((β=0.626, SE=0.162, p=.058))."

Discussion¶

Related Claims¶

• Retention interval moderates the testing effect: effects are larger after a day or more than at shorter intervals, where individual studies vary from reliable to null or reversed — related
• Retrieval practice effects are larger at retention intervals greater than 1 day (g = 0.69) than at intervals less than 1 day (g = 0.41) in Rowland's (2014) meta-analysis — related
• The testing effect is largest at a retention interval of 1–6 days (g = 0.82) and robust across all intervals — related
• Retrieval practice produces reliable positive effects at short delays, although some forgetting must set in so that the final test is not at ceiling — related
• The testing effect for mathematics learning (testing versus restudy, g = 0.22) is not robust, as its 95% confidence interval crosses zero. — related
