Block practice was faster during training, but varied practice performed better later
Among 48 healthy men, those who alternated conditions performed better later and with the other hand. Sleep showed no advantage over staying awake.
The key idea
In this movement task, repeating in blocks worked better at first, varied practice performed better later, and sleep showed no advantage on the main outcome.
The study, in plain language
Learning a movement does not end when practice stops. The team compared two ways of training a motor task: repeating each movement type in blocks or alternating between different conditions. They then observed performance after an interval.
During training, the block-practice group adapted faster. At the later test, and when using the other hand, the group that varied its practice performed better. Sleeping overnight showed no advantage over staying awake during the day on the main outcome.
What they found
- Repeating each movement in blocks led to faster adaptation during training.
- Those who varied their practice performed better later, both at the later test and with the other hand.
- The main result was similar for those who slept and those who stayed awake during the interval.
Something to think about
Think about something you are practicing: when do you feel you do it better, while repeating it or when trying it later? Here, what went best during practice was not what performed best afterward.
How they studied it
Forty-eight healthy adult men practiced movements against force fields, either in blocks or by alternating conditions. An 11-hour interval with overnight sleep or daytime wakefulness followed, and brain activity was recorded during the task and sleep. The sample included only men. Associations between EEG patterns and consolidation are exploratory and do not prove that sleep caused an improvement.
What the study cannot show
- Only young men took part, and the study tested one specific motor task over a specific 11-hour interval.
- The result does not show that sleep never helps learning or that block practice is better for every skill.
