We are now establishing how important sleep is for children particularly those with learning difficulties.  In a recent study we used a newly developed child-friendly target detection game presented on an iPad® to understand more about the impact of sleep upon performance in typically developing children.  We found that sleep appeared to stabilise their ability to hit targets accurately, in contrast with a similar daytime period where they became worse.  This game has allowed us to demonstrate how important sleep is for maintaining attention and we plan to use it to answer other questions about sleep and development within clinical settings.
