This report reviews, analyzes, and summarizes experimental literature on sleep learning. Findings are as follows 1 Serious methodological flaws were found in all reported positive results. There is no evidence that semantic learning occurs when verbal material is presented to sleeping subjects. 2 A critical, but open-minded, test of sleep learning has not been done. Recommendations are made for an appropriate experiment. 3 If new material is presented to the sleeping subject, there is danger that it may interfere with normal nighttime processing of earlier daytime experiences.
