Sacrificing sleep for extra study time is counterproductive

Sydney: Trying to master a new skill or new dance steps? Make sure you take good breaks while training because you`ll learn faster than if you push yourself non-stop, suggests a new study.

Psychology researchers Soren Ashley and Joel Pearson from the University of New South Wales found that adopting a "practice makes perfect" approach has limits: train too much and the law of diminishing returns cuts in to impede progress.

Learning a new skill involves rewiring of the brain, a phenomenon called neural plasticity. For the new skill to persist, those brain changes must be stabilised or consolidated by being transferred from short-term memory and locked into long-term memory, the journal Proceedings of the Royal Society B reports.

"If the information and/or neural changes are not adequately consolidated, then learning will be temporary or not occur at all," the researchers say, according to a New South Wales statement.

Other research has found that lack of sleep, for example, can interfere with the consolidation process, as can trying to train for a second skill before the first one has properly sunk in.

"Many studies have shown that you don`t learn if you don`t sleep after a day of training," says Pearson. "Likewise, overtraining can reduce learning if you don`t allow time for consolidation."
