Subclaims¶

q3 i? No significant correlation was found between polysomnographic parameters and memory consolidation measures in either group. → Holz J 2012 q3 i? No significant differences in any sleep parameters were found between the two training-time groups. → Holz J 2012 (2)

Evidence¶

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

Bivariate Pearson correlation analyses between polysomnographic parameters and memory-task performance in the randomized experiment found no significant correlations (P > 0.05); no effect sizes are printed.

"Analyses of the association between polysomnographic parameters and measures of memory consolidation in the experimental groups did not reveal any significant correlation (P.0.05, results not shown)."

q3 · i? · causal · r2

One-way ANOVAs on polysomnographic parameters (Table 3, e.g. sleep latency P = 0.072, slow wave sleep P = 0.099) showed no significant group differences; the authors note slight non-significant differences might have contributed to the memory results.

"Analyses revealed normal sleep data and no significant differences in any of the sleep parameters between the groups."

Discussion¶

Related Claims¶

• Sleep and consolidation support semantic memory development, suggesting delayed school start times may benefit memory — related
• 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
• Evening-trained adolescents show greater gains in finger-tapping accuracy (reduced error rate) than afternoon-trained adolescents at both retention intervals — related
• Free-living sleep measures show no association with visual attention task performance in older adolescents — related
• Weekly average sleep measures show no association with working memory performance in older adolescents — related
