Subclaims

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.

q3 i? In both contiguous and spaced conditions, roughly two thirds of participants rated blocking as more effective, significantly above chance. → Monica S. Birnbaum 2013

Evidence

Monica S. Birnbaum, Nate Kornell, Elizabeth Ligon Bjork, & Robert A. Bjork. (2013). Why interleaving enhances inductive learning: The roles of discrimination and retrieval. Memory & Cognition, 41, 392–402. https://doi.org/10.3758/s13421-012-0272-7

q3 · i? · causal · r2

Post-test judgment among the 114 Experiment 2 participants: 65% (37/57) favored blocking in the contiguous condition (z = 2.12, p < .05) and 67% (38/57) in the spaced condition (z = 2.38, p < .05), despite blocking being counterproductive or ineffective. No effect size is printed for this judgment difference.

"In the contiguous condition, 65 % (37/57) of the participants favored blocking. A binomial test using an approximation of the normal distribution showed this ratio to be significantly different from chance (i.e., from 50 %), z 0 2.12, p< .05"
