    • Abstract:
      To test the effects of REM sleep on the amount and kind of material recalled after a 7-hr interval, five groups of 10 student subjects were tested for immediate and delayed recall of 70 adjectives before and after varying amounts of REM time. There were no significant between group differences in total amount of delayed recall but there were differences in the number of new words retrieved. Following a REM present condition subjects recalled more new words than following a REM absent condition. The properties associated with words recalled later differed following different conditions. The new words available to recall only after REM absent sleep were self affirming items. Those which became available following REM present sleep were items of personal discomfort. The nature of the intervening psychophysiological states appeared to affect the kind of material recalled. [ABSTRACT FROM AUTHOR]
