How they designed this study was to have the participants that were in this sample were split into two groups, they were either reported to earl night condition or to a late night condition. In the early sleep condition the participants learned the task between learning two class times. They then had to go into retrieval phase between another two time periods to test the delay task recall. In the late sleep condition the participants slept for three hours before learning phase, and then a three hour retention interval of REM sleep- dominated sleep followed. The retrieval phase took place much later in the test. The results revealed that superior retention for negative or neutral pictures only after the late REM sleep-rich retention interval, whereas no such difference was detected after early slow wave
