Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q4 i? The meta-regression found no moderating effect of retention interval, retention vs. transfer test format, simultaneous vs. successive presentation, or publication status on the interleaving effect. → Brunmair 2019 q4 i? In a follow-up analysis of 31 studies assessing both test types, retention and transfer effects did not differ (QM = 0.56, p = .45). → Brunmair 2019 (2) q4 i? Simultaneous presentation tended to yield a higher interleaving effect than successive presentation, but the difference was not significant. → Brunmair 2019 (3)

q4 · i? · quant-synthesis · r?

Meta-regression moderator tests in the full multilevel models (Table 3); the article reports no moderating effects for retention interval, presentation mode, test type, or publication status, without printed effect sizes for these null findings.

"We found no evidence for a moderating effect of retention interval in the meta-regression analysis."

q4 · i? · quant-synthesis · r3

Follow-up meta-regression on effects from 31 studies that assessed both retention (old items) and transfer (new items) within the same sample; no difference between test types.

"In a meta-regression of these studies, we found no overall effect of retention vs. transfer ( k = 64, QM = 0.56, p = .45)."

q4 · i? · quant-synthesis · r3

Follow-up analysis restricted to studies operationalizing both presentation styles (k = 26); both modes showed positive interleaving effects and the between-mode difference was not significant.

"The interleaving effect tended to be higher in simultaneously presented items (g = 0.44, p < .001, 95% CI [0.24, 0.64]) than in successively presented items ( g = 0.29, p = .005, 95% CI [0.09, 0.50]), but the difference was not significant ( k = 26, QM = 1.0 p = 0.31)."
