Studies on sleep and memory primarily focus on overnight rather than long-term performance changes. Investigating associations between performance changes and sleep architecture benefit from more in-depth analyses of sleep characteristics (i.e. sleep spindles and slow oscillations). The present study investigated the effects of full-night sleep on procedural memory performance after one night and a one-week follow-up. Additionally, the functional significance of spindles and slow oscillations for procedural memory consolidation will be investigated. Participants (N = 23, Mage = 23.17 ± 2.66 years) were trained on a procedural mirror-tracing task during counterbalanced learning (mirrored vision) and control (normal vision) conditions. Participants traced 12 figures as quickly and accurately as possible within a 90s timeframe during the evening training session. Performance was evaluated for speed and accuracy directly following training, after a fullnight of sleep, and a one-week follow-up. Twenty-one channel electroencephalography was recorded during task execution, with polysomnography recorded during the night. Performance changes, sleep architecture, as well as spindle and slow oscillation activity were analyzed for both conditions. Preliminary findings indicate no performance changes for the control condition. The learning condition showed no overnight improvement for speed but rather a significant improvement during the follow-up. In contrast, accuracy significantly increased following full-night sleep and stabilized for the subsequent followup. Further associations between performance changes, sleep spindles, and slow oscillations will be investigated. This study shows that performance on a procedural memory task can be improved by full-night sleep, and that additional performance changes can occur after a longer time period.
