One of the two experiments included a recall test at the end of the session: The participants who had relaxed, eyes closed, for 10 minutes performed better on the memory exercise than those who had stayed busy. Both experiments included a recall test seven days later. In each case, the people who had taken the spell of wakeful rest remembered more details about the stories.
