Summary: Contrary to common beliefs, adults can learn new motor skills faster than children, but children retain these skills better due to more effective sleep-driven memory consolidation. In a recent study, adults showed faster skill acquisition, while children demonstrated superior retention after sleep.
The findings highlight how age affects the motor learning process, with implications for skill training and rehabilitation strategies. Adults’ mature cognitive abilities likely contribute to faster learning, while children’s sleep aids memory consolidation. These insights can benefit professionals in fields like sports, education, and physical therapy.
Key Facts:
- Adults learn motor skills faster, but children retain them better after sleep.
- Children improve in skill performance overnight, while adults tend to lose some ability.
- These findings could guide skill training, rehabilitation, and teaching strategies.

Contrary to popular belief, children aren’t better at learning new skills than adults. Indeed, young adults seem to learn faster than kids – but also tend to forget more quickly. Here, better sleep seems to advantage children. This is the conclusion of a new study from the University of Copenhagen.
It’s widely believed that children learn new motor skills faster than adults, whether it’s mastering slopes or skateparks, learning new languages, doing cartwheels or picking up new dance moves from TikTok.
“There’s an assumption in popular science literature and various textbooks that children in a certain age range – from roughly the age of eight until puberty – are better at learning new skills than adults.
“This is often described as a ‘golden age for motor skills learning’. But there’s no actual physiological basis for this so-called golden age,” says Jesper Lundbye-Jensen, associate professor at the University of Copenhagen’s Department of Nutrition, Exercise and Sports and head of the section ‘Movement & Neuroscience.
The popular notion of a pre-pubescent motor learning peak prompted the researchers to investigate how age-related differences in our central nervous system affect motor skill learning.
Their findings are now published in Developmental Science.
In the study, the researchers tested the motor learning abilities of 132 participants from four age groups: 8-10 years, 12-14 years, 16-18 years, and 20-30 years. In a lab setting, participants practiced moving a cursor on a computer screen with fast and precise finger movements.
Older participants learned faster
Participant performance was measured immediately after being introduced to the task (as a baseline), during the training session, and again 24 hours later.
During the training session itself, both the 16-18-year-olds and 20-30-year-olds improved their skills significantly more than the 8-10-year-olds.
“So, it appears that both teenagers and younger adults are better equipped to quickly acquire new skills compared to children, who showed smaller and slower improvements.
“At least when it comes to short-term learning and motor skills which this study investigated” explains Mikkel Malling Beck, the research article’s lead author and a former PhD student at the Department of Nutrition, Exercise and Sports who now works as a researcher at the Danish Research Centre for Magnetic Resonance at Hvidovre Hospital.
While the researchers cannot pinpoint the exact reasons for why the adults learn faster, they have a few theories.
“The results demonstrate that the older the participants are, the more skillful they become during the early stages of training.
“This suggests that they get more out of the task introduction. We suspect that cognitive development and an increased ability to process information play a role – meaning adults may have more experience receiving instructions and translating them into action,” says Jesper Lundbye-Jensen, adding:
“The difference may also be because the fully developed nervous system of an adult provides better structural conditions for learning. In other words, after many years of schooling, adults may be more experienced learners and thereby more efficient at learning new things.”
Children benefit more from sleep
The picture changes when it comes to retention:
“When we look at what happens from the end of training until the participants return the next day, the dynamic reverses. While the youngest participants actually improve overnight, adults lose some of their ability to perform. This means the youngest ones are better at consolidating and reinforcing their memory after they’ve practiced,” says Mikkel Malling Beck.
According to the researchers, this suggests that sleep benefits children’s learning and memory more. But other factors could also be at play. For example, older children and adults typically sleep less and have more “competing” activities throughout the day. Memory-consolidation processes in the nervous system continue for hours after the training ends.
“When a math class ends, the brain keeps working on what was taught, and in doing so, reinforces memory. Sleep is known to aid consolidation. But engaging in other activities in the hours after –especially those that involve learning – can interfere with memory processes and the consolidation of what was just learned,” explains Jesper Lundbye-Jensen.
Potential applications for professionals
While the overall learning outcome doesn’t vary drastically across age groups, the study does show that the learning process differs significantly depending on age, with underlying mechanisms influenced by the maturity of one’s central nervous system.
According to the researchers, the results could be useful in teaching and training fields that involve skill and movement, such as sports and music. Jesper Lundbye-Jensen points out that the results are relevant in other areas as well:
“For anyone aiming to improve their skills, it’s crucial to structure training so that each individual gets the most out of their time. This is also true for people undergoing rehabilitation to regain functional ability.
“We hope that this new understanding of age-related differences and post-training processes will inspire physiotherapists, occupational therapists, and other professionals when designing training protocols.”

“Distinct mechanisms for online and offline motor skill learning across human development” by Jesper Lundbye-Jensen et al. Developmental Science
Abstract
Distinct mechanisms for online and offline motor skill learning across human development
The human central nervous system (CNS) undergoes tremendous changes from childhood to adulthood and this may affect how individuals at different stages of development learn new skills.
Here, we studied motor skill learning in children, adolescents, and young adults to test the prediction that differences in the maturation of different learning mechanisms lead to distinct temporal patterns of motor learning during practice and overnight.
We found that overall learning did not differ between children, adolescents, and young adults. However, we demonstrate that adult-like skill learning is characterized by rapid and large improvements in motor performance during practice (i.e., online) that are susceptible to forgetting and decay over time (i.e., offline).
On the other hand, child-like learning exhibits slower and less pronounced improvements in performance during practice, but these improvements are robust against forgetting and lead to gains in performance overnight without further practice.
The different temporal dynamics of motor skill learning suggest an engagement of distinct learning mechanisms in the human CNS during development.
In conclusion, adult-like skill learning mechanisms favor online improvements in motor performance whereas child-like learning mechanisms favors offline behavioral gains.
