Abstract : Three studies are reported on: (1) A factor analytical investigation of questionnaire data to help establish the attributes of individuals who habitually nap as opposed to others who do not; (2) A study over eight sessions comparing the physiological napping behavior of habitual nappers versus individuals who do not normally nap; and (3) A study currently in progress evaluating the effect of napping on performance in partially sleep-deprived individuals. Previous observations about the deleterious effects of naps involving delta sleep on performance immediately on awakening were again observed. One of the more striking findings is that nappers seem to perceive descending Stage I sleep as more like being awake while non-nappers describe it as sleep. Further, it would appear that daytime serves appetitive functions in addition to facilitating recovery from fatigue in non-sleep-deprived habitual nappers. The likelihood that there are functional differences in napping behavior between nappers and non-nappers is discussed. (Author)
