The present experiment permitted a systematic comparison of the effects of Stage 4 and 1-REM sleep deprivation. One group of Ss was deprived of Stage 4 sleep for 7 nights while another was deprived of 1-REM sleep. Measurements of the EEG during sleep and of personality variables revealed that the two types of deprivation are quite different. Stage 4 deprivation resulted in a sharp increase in Stage 2 sleep on deprivation nights while 1-REM deprivation resulted in an increase in Stage 1 without rapid eye movements. Stage 4 deprivation produced a depressive outlook in 5s while 1-REM deprivation resulted in a state of higher irritability and lability.
