摘要: Learning of a procedural motor-skill task is known to progress through series unique memory stages. Performance initially improves during training, and continues improve, without further rehearsal, across subsequent periods sleep. Here, we investigate how this delayed sleep-dependent learning affected when the characteristics are varied several degrees difficulty, whether improvement differentially enhances individual transitions motor-sequence pattern being learned. We report that subjects show similar overnight improvements in speed five-element unimanual sequence (17.7% improvement), nine-element (20.2%), or bimanual (17.5%), but markedly increased (28.9%) with sequence. In addition, within appeared most difficult at end training showed significant 17.8% increase overnight, whereas those were performed rapidly only non-significant 1.4% improvement. Together, these findings suggest process selectively provides maximum benefit procedures proved be prior
