Unraveling the time-of-day influences on motor consolidation through the motor-declarative memory conflict.

ABSTRACT: Competition between motor and declarative memory systems, both involved simultaneously in motor learning, has been shown to reduce motor consolidation. Here, we investigated this conflict during the learning of a sequential finger-tapping task (SFTT) scheduled for either the morning or the afternoon. Sixty participants, divided into four groups, trained on SFTT at either 10 a.m. or 3 p.m., and retested five hours later. To disrupt the conflict between the two memories, two groups underwent declarative learning immediately after SFTT training, involving word list training (G10_DL and G3_DL), while the two other groups (G10_CTR and G3_CTR) experienced no additional learning. The results revealed that after morning training without additional learning (
