q3 i? Total early learning and microscale learning did not differ between a 5 s practice period group and a 10 s practice period group, and microscale learning was statistically equivalent (TOST). → Marlene Bönstrup 2020

q3 · i? · causal · r2

Experiment 3: 181 participants trained 48 trials of alternating 5 s practice and 10 s rest, compared with the 10 s practice group. Micro-offline gains remained substantial in both groups (5 s: 1.89 ± 0.23; 10 s: 1.48 ± 0.17 keypresses/s, P < 0.001), inconsistent with a substantial contribution of motor slowing.

"No signi ficant differences in total early learning or microscale learning were evident ( P > 0.05) and microscale learning between groups was statistically equivalent (TOST for equivalence)."

Discussion¶

Related Claims¶

• Micro-offline gains are inconsistent with a dominant contribution of latent motor slowing, supporting consolidation as their driver — related
• Random termination of practice periods does not reduce micro-offline gains, ruling out preemptive motor slowing — 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 — related
