Research that examines changes in a specific behavior across the human lifespan frequently reports an inverted–U trajectory. That is, young adults exhibit optimal performance, children are conceptualized as developing systems progressing towards this ideal state, and older adulthood is characterized by performance decrements. However, not all behaviors follow this trajectory. Notably, there are instances – and in the learning and memory domain in particular – in which children outperform young adults and thus can be considered the model of optimal performance. This study aimed to reveal instances of childhood advantage in the domain of motor learning and memory consolidation. Motor sequence learning data were acquired from 7 to 35 and >55–year–old participants across two experiments via an online data acquisition platform. In Experiment 1 (n=130), participants learned an 8-element, bimanual motor sequence in a single practice session. In Experiment 2 (n=108), participants acquired the same sequence and were retested 5 and 24 hours after initial acquisition, affording the assessment of memory consolidation across offline periods including both wakefulness and sleep. Results from Experiment 1 revealed comparable initial learning dynamics among age groups, but 7– to 12–year–old children exhibited smaller sequence–specific learning relative to adolescents (13–17 years), young adults (18–35 years) and older adults (> 55 years). Interestingly, children tended to demonstrate the greatest performance gains over the short rest epochs interspersed with practice (i.e., 'micro'–offline intervals). Results from Experiment 2 revealed that this developmental advantage was not limited to the micro–offline timescale. Children and adolescents exhibited larger performance gains in the delayed retests, reflecting enhanced 'macro'–offline motor memory consolidation. Collectively, these results suggest that children exhibit a developmental advantage in the offline processing of recently practiced motor sequences.
