Abstract

Non-pathological sleep parameters in relation to cognition among individuals who do not qualify as having sleep disorders or who are not subjected to extended periods of total sleep deprivation have not been adequately investigated in previous studies. The current study investigates the influence of circadian typology (morning-type vs. evening-type individuals), time of session (AM vs. PM), habitual sleep practices (sleep hygiene), sleep quality, life stress, and the presence of an acute stressor on sustained attention, memory, and mental rotation performance. Several main effects emerged for individual variables above; however, the data failed to reveal significant interactions among these variables. The evidence in this study of non-pathological sleep parameters affecting cognitive performance presents a need for further investigation.
