Another report of research (this one from Soren Ashley and Joel Pearson) showing the importance of time for reflection, and consolidation of learning. Although effort, practice, and persistence are all prerequisites for learning, it seems that all work and no play really does make Jack a dull boy, in the sense of not as smart as he would be if he had more time for play.
A quote from the article:
‘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. “If the information and/or neural changes are not adequately consolidated, then learning will be temporary or not occur at all,” the researchers say.’
