Subclaims¶

q3 i3 Total early learning on an implicit SRTT was significant (d = 2.73) and was accounted for by micro-offline performance gains during rest (d = 0.64) rather than micro-online gains within practice, which were not significant. → Emily Brooks 2024

q3 · i3 · causal · r2

Controlled experiment: 38 adults completed an implicit serial reaction time task alternating 10-s practice and rest; analysis restricted to blocks 1-7. Total learning d = 2.73 and micro-offline gains M = 0.84 were significant; the article reports micro-online gains were not (t(33) = 0.22, p = 0.83). The "early learning was accounted for by performance gains during micro-offline periods".

"Across the entire sample we observed significant total learning ( M = 0.60, SD = 0.22), t (33) = 15.89, p < 0.001, 95% CI [0.52, 0.68], d = 2.73. At the group level, this early learning was accounted for by performance gains during micro-offline periods (M = 0.84, SD = 1.32)"

Discussion¶

Learner Variables¶

• Long-Term Memory — outcome: instruction changes it

Related Claims¶

• A preceding bout of HIIT exercise does not influence micro-consolidation of an implicit motor sequence learned in close temporal proximity to exercise — related
• Performance improvements during early motor skill learning occur predominantly during short rest periods (micro-offline gains), replicated in a large crowdsourced sample and in a laboratory study — possibly the same claim (merge candidate)
• Random termination of practice periods does not reduce micro-offline gains, ruling out preemptive motor slowing — related
• The magnitude of micro-online and micro-offline gains is strongly related across participants (r = -0.96 between subjects) — related
• Halving practice-period duration from 10 s to 5 s leaves micro-offline gains unchanged, arguing against recovery from motor fatigue — related
• Micro-offline gains are inconsistent with a dominant contribution of latent motor slowing, supporting consolidation as their driver — related
• A single 10-second practice trial of motor skill A produces micro-offline generalization, with performance at the onset of skill B exceeding the end of skill A — related
• Retroactive interference immediately after practice reduces the learning rate relative to interference after 10 s of rest, indicating within-seconds memory stabilization — related
