Subclaims¶

q3 i? Evening-group adolescents showed a greater improvement in tapping accuracy than afternoon-group adolescents across both retention intervals. → Holz J 2012

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

Same randomized finger-tapping experiment, accuracy measure (error rate). Table 2 reports error-rate changes of 0.1 vs -3.1 on Day 2 (P = 0.022) and 0.3 vs -3.7 on Day 8 (P = 0.006); no standardized effect size is printed.

"Furthermore, the analysis also revealed a greater improvement in accuracy in the EG compared to the AG for the retention interval from Day 1 to Day 2 (Tab. 2, Fig. 3c), as well as for the interval from Day 1 to Day 8 (Fig. 3d)."

Discussion¶

Related Claims¶

• Adolescents trained on a finger-tapping task in the evening show greater off-line gains in tapping speed than afternoon-trained adolescents at both 24 hours and 7 days
• 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
• 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 — related
• Polysomnographic sleep parameters did not differ between afternoon- and evening-trained groups and did not correlate with memory consolidation measures — related
