“Researchers thought that retention of newly learned skills might be affected by sleep after learning. After learning a new task, half of the subjects slept at least six hours and the others were kept awake all night. Participants who slept at least 6 hours scored significantly higher (M = 72, SD = 7.93) than those who stayed awake all night (M = 61, SD = 8.07) on a visual discrimination task learned the previous day (t (14) = 2.75, p = .025).”
