A new study from Lancaster University has found that sleeping on a problem really can help people to find a solution.
The study, published online this week in the journal Memory & Cognition, tested whether sleep or time spent awake worked best in helping people find the solutions to a range of problem solving tasks.
Participants in the study – 27 men and 34 women – were asked to attempt easy and difficult verbal insight problems and, following a period of sleep, time spent wake, or no delay at all, the three groups of participants reattempted previously unsolved problems.
The sleep group solved a greater number of difficult problems than did the other groups, but no difference was found for easy
The authors of the study – Ut Na Sio, Padraic Monaghan and Tom Ormerod all from the Centre for Research in Human Development and Learning at Lancaster’s Department of Psychology – concluded that sleep facilitates problem solving but this has its primary effect for harder problems.
