Consolidation Based on Stabilization in Implicit Motor Memory

Time supports the consolidation of motor sequence memories, yet it remains unclear whether time duration and doing specific task in this time, stabilizes or actually enhances motor sequence performance. The aim of this study was to investigate time duration with specific interference on consolidation human motor memory. Forty-five healthy volunteer participate performed Serial Color matching task for three blocks of 150 trials. They randomly divided into three group, 1) after one hour 2) after six hour performed finger-to-thumb opposition task 3) without any interference. All group after 24 hour participated in retention test. The result show no significant differences between acquisition and retention stages. These findings indicate rapid stabilization of implicit motor memory and interference sequential finger-to-thumb opposition task and time had no enhancement or reducer effect on implicit motor memory, but rather stabilizes motor sequence performance without producing additional gains.
