Results. (a) For memories rated as certain (correct—incorrect), the nap group remembered significantly more than the wake group at 30 min and day-8 tests. The cram group remembered significantly more than the wake group at 30 min but not the day-8 test. (b) A similar pattern emerged for overall memory, except the only significant difference was between nap and wake groups at the 30 min test. Mean ± SEM.
