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.
q2 i? A two-way ANOVA found no significant group × sex interaction and no significant main effect of sex, but a significant main effect of group favouring the Nap group. → Vidal 2025
Evidence¶
Vidal 2025¶
Vidal, V., Pretel, M. R., Capurro, L., Tassone, L. M., Moyano, M. D., Malacari, R. G., Brusco, L. I., Ballarini, F. M. & Forcato, C. (2025). Short naps improve subsequent learning in a high school setting. npj Science of Learning 10:15. https://doi.org/10.1038/s41539-025-00307-4
q2 · i? · causal · r2
Exploratory two-way ANOVA with sex and group as between-subjects factors (N = 76). No group × sex interaction (F(1,72) = 0.33, p = 0.569) and no sex main effect (F(1,72) = 2.80, p = 0.099); "a significant main effect of group was observed" with no effect size printed.
"a significant main effect of group was observed (F(1,72) = 10.62,p = 0.002), with the Nap group outperforming the Control group in encoding performance"
Discussion¶
Learner Variables¶
- Gender — moderator: an instructional effect differs by group
Related Claims¶
- Female children and adolescents recognize vocal emotions more accurately than males, with no interaction between sex and age — related
