The Effects of Direct Context Reactivation During Sleep on Memory

I will unobtrusively and repeatedly present learning-related sounds during sleep using speakers. This method was shown to improve memory in various tasks. The sounds will be presented several seconds apart and the volume will be so adjusted as not to disturb the participant's sleep. The sounds will be presented during non-rapid eye movement sleep (sleep stage 2 and slow wave sleep). The sounds presented will be non-congruently related to the scenes in the previous learning task. This manipulation is within-subject - all participants will get it, but different specific sounds will be presented for each individual participant.
