Little children do indeed sleep sweetly.
In fact, according to Gareth Gaskell at the University of York and Anna Weighall, children need good quality sleep to consolidate the vocabulary they’ve learnt during the day. They say that the new words are fully integrated with familiar words after 12 hours – but only if they slept well during that period.
But we knew that, didn’t we?
We already know that sleep is part of the memory consolidation process. And if you really want to learn something well, a quick ziz will go a long way.
Are you feeling sleepy?
