Abstract

Sleep has an important effect on planning and decision-making abilities, which are integral to daily functioning and quality of life. Cronotype is the propensity to sleep at a particular time during a 24-hour period. Chronotype change across the lifespan, with adolescents and young adults preferring a delayed sleep period, which does not fit with societal norms and often results in social-jetlag. Social-jetlag might impact executive functioning and thus the ability for students to function adequately. As such, the aims of this study are to explore whether 1) there is an interaction effect of chronotype and social-jetlag on tests of executive functioning, and whether 2) there is a difference in executive functioning abilities between those with early and late chronotypes. Thirty-seven university students (mean age= 24.7) underwent an observational cross-sectional study. Measurements included, the Munich Chronotype Questionnaire, the Depression Anxiety Stress Scale, and the computerized tests of Planning (Tower of London) and Decision-making (Iowa Gambling Test). The results of two-way ANCOVAs showed a significant difference in planning, but not decision-making between early and low chronotype groups. The results of this study will have great implications for research, practice, and, policy regarding the alteration of college schedules based on students’ biological clocks.
