“…In the present article, we focus on performance of older adults during sequence learning and motor adaptation. We match the findings to data obtained in younger adults (Backhaus et al, 2016 ). Based on previous results which showed learning improvements during sequence learning in older adults (Howard and Howard, 1989 ; Spencer et al, 2007 ) and findings which showed the capability of older adults to adapt to new movements and movement components (Voelcker-Rehage, 2008 ), we hypothesized behavioral improvements of older adults in both learning paradigms.…”

“…The term “motor adaptation” incorporates the learning of new movements on top of previously known automated movement patterns, leading to a change in learned movement patterns. One example of a motor adaptation tasks are joystick tracking tasks, as previously studied in young adults (Doyon et al, 2009 ; Backhaus et al, 2016 ). No sleep-dependent gains could be shown after a daytime nap in younger adults.…”

The impact of sleep on motor learning in the aging brain was investigated using an experimental diurnal nap setup. As the brain ages several components of learning as well as motor performance change. In addition, aging is also related to sleep architectural changes. This combination of slowed learning processes and impaired sleep behavior raises the question of whether sleep can enhance learning and specifically performance of procedural tasks in healthy, older adults. Previous research was able to show sleep-dependent consolidation overnight for numerous tasks in young adults. Some of these study findings can also be replicated for older adults. This study aims to clarify whether sleep-dependent consolidation can also be found during shorter periods of diurnal sleep. The impact of midday naps on motor consolidation was analyzed by comparing procedural learning using a sequence and a motor adaptation task, in a crossover fashion in healthy, non-sleep deprived, older adults randomly subjected to wake (45 min), short nap (10–20 min sleep) or long nap (50–70 min sleep) conditions. Older adults exhibited learning gains, these were not found to be sleep-dependent in either task. The results suggest that daytime naps do not have an impact on performance and motor learning in an aging population.

“…In several studies, researchers have identified a number of moderating variables that may account for at least a portion of the performance improvement following sleep (see Pan and Rickard, 2015, for a comprehensive review and meta-analysis). Some of these data even suggest that under some circumstances, skill performance after sleep may not be better than after a period of wakefulness (e.g., Backhaus et al, 2016), inviting a reconsideration of sleep’s theoretical role in the consolidation of procedural memories (Nettersheim et al, 2015). This debate is still unresolved at present.…”

Task Complexity Modulates Sleep-Related Offline Learning in Sequential Motor Skills

Recently, a number of authors have advocated the introduction of gross motor tasks into research on sleep-related motor offline learning. Such tasks are often designed to be more complex than traditional key-pressing tasks. However, until now, little effort has been undertaken to scrutinize the role of task complexity in any systematic way. Therefore, the effect of task complexity on the consolidation of gross motor sequence memory was examined by our group in a series of three experiments. Criterion tasks always required participants to produce unrestrained arm movement sequences by successively fitting a small peg into target holes on a pegboard. The sequences always followed a certain spatial pattern in the horizontal plane. The targets were visualized prior to each transport movement on a computer screen. The tasks differed with respect to sequence length and structural complexity. In each experiment, half of the participants initially learned the task in the morning and were retested 12 h later following a wake retention interval. The other half of the subjects underwent practice in the evening and was retested 12 h later following a night of sleep. The dependent variables were the error rate and total sequence execution time (inverse to the sequence execution speed). Performance generally improved during acquisition. The error rate was always low and remained stable during retention. The sequence execution time significantly decreased again following sleep but not after waking when the sequence length was long and structural complexity was high. However, sleep-related offline improvements were absent when the sequence length was short or when subjects performed a highly regular movement pattern. It is assumed that the occurrence of sleep-related offline performance improvements in sequential motor tasks is associated with a sufficient amount of motor task complexity.

“…Many of them caution against napping too long or too late in the day. Backhaus, et al (2016) found no difference in learning motor skills between those subjects who took short naps, long naps, or no naps.…”

Naps and Sleep Deprivation: Why Academic Libraries Should Consider Adding Nap Stations to their Services for Students

Since the invention of artificial light, people have been working, studying and playing for longer hours than ever before. They are also sleeping less as a result. This article examines the impact of sleep deprivation on people generally, and specifically on college students. Students accrue a large sleep debt that impairs their ability to function adequately. Students suffering from sleep deprivation can be as impaired as if they are drunk. They suffer damage to their minds and bodies. Adequate sleep can repair this damage, but with the many demands on college students, they may be unlikely to be able to accomplish this. Studies have indicated that naps are beneficial in helping to reduce students' sleep debts. Universities are realizing the importance of naps, and university libraries may be ideal locations for napping stations. Several options of providing students with safe comfortable napping areas are discussed.
