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? Evening-group adolescents improved finger-tapping speed significantly more than afternoon-group adolescents across both retention intervals. → Holz J 2012
Evidence¶

Holz J, Piosczyk H, Landmann N, Feige B, Spiegelhalder K, Riemann D, Nissen C, Voderholzer U. (2012). The Timing of Learning before Night-Time Sleep Differentially Affects Declarative and Procedural Long-Term Memory Consolidation in Adolescents.

q3 · i? · causal · r2
Randomized parallel-group experiment (25 per group) on a five-element finger-tapping sequence. Table 2 reports speed differences of 4.8 vs 6.1 sequences on Day 2 (P = 0.020) and 6.8 vs 9.0 on Day 8 (P = 0.002); no standardized effect size is printed.
"Univariate ANOVAs revealed a significantly greater improvement in finger-tapping speed in the EG compared to the AG across the first retention interval from Day 1 to Day 2 (Tab. 2, Fig. 3a), as well as for the interval from Day 1 to Day 8 (Tab. 2, Fig. 3b)."
Discussion¶
Related Claims¶
- Evening-trained adolescents show greater gains in finger-tapping accuracy (reduced error rate) than afternoon-trained adolescents at both retention intervals
- Learning timing produces Group X Time interactions in both memory systems: declarative consolidation time courses differ between afternoon and evening groups, and finger-tapping speed and accuracy show highly significant Group X Time interactions
- Polysomnographic sleep parameters did not differ between afternoon- and evening-trained groups and did not correlate with memory consolidation measures
- Adolescents trained on word pairs in the afternoon show higher word-pair retention after 24 hours than evening-trained adolescents, but the difference is not sustained at 7 days — related
