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 i2 Making JOLs with word stems decreased internal intrusions compared to restudy (d = 0.69), and retrieval practice did so as well (d = 0.57), while JOLs with complete words did not (d = 0.23, ns). → Veit Kubik 2022

Between-subjects ANOVA on internal intrusions during interim List-5 recall showed a main effect of practice type, F(3, 157) = 2.97, p = .034, ω²p = 0.04; planned contrasts showed intrusions "decreased only for making JOLs with word stems, compared to restudy". Retrieval practice also reduced intrusions versus restudy, t(46.84) = 1.97, p = .027, d = 0.57.
"the number of internal intrusions was decreased only for making JOLs with word stems, compared to restudy, t(42.83) = 2.26, p = .015, d = 0.69, 95% CI [0.17, ∞] (one-tailed), but again not for making JOLs with complete words, t(62.38) = 0.91, p = .365, d = 0.23, 95% CI [-0.27, 0.73]"
Discussion¶
Related Claims¶
- On the final cumulative test, JOLs with word stems and retrieval practice improve List-5 recall over restudy, while restudy shows a List-1 advantage — related
- Making JOLs with complete words did not significantly enhance interim recall of new List-5 material compared to restudy — related
- JOL magnitudes decline across successive lists in both JOL groups, reflecting learners' belief that recall decreases with continued new learning — related
- Making JOLs with word stems enhances interim recall of new List-5 material compared to restudy — related
- Overt retrieval practice enhances interim recall of new List-5 material compared to restudy, and does not differ from JOLs with word stems — related
