Abstract

The influence of sleep on motor skill consolidation has been a research topic of increasing interest. In this study we distinguished general skill learning from sequence-specific learning in a probabilistic implicit sequence learning task (Alternating Serial Reaction Time) in young and old adults before and after a 12-hour offline interval which did or did not contain sleep (pm-am and am-pm groups respectively). The results showed that general skill learning, as assessed via overall RT, improved offline in both the young and older groups, with the young group improving more than the old. However, the improvement was not sleep-dependent, in that there was no difference between the am-pm and pm-am groups. We did not find sequence-specific offline improvement in either age group for either the am-pm or pm-am groups, suggesting that consolidation of this kind of implicit motor sequence learning may not be influenced by sleep.
