The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night' s sleep than after the same time spent awake during the day. They also found it easier to remember themes (主题) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to fard out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢复的) value.
