Deficient Sleep in Teens:  The Impact on School Performance - Amy Wolfson, PhD


Deficient Sleep in Teens:  The Impact on School Performance - Amy Wolfson, PhD, Vice President for Academic Affairs and Professor of Psychology, Loyola University Maryland

Dr. Wolfson reviews literature on the relationships linking school start times, sleep, and academic performance.  The main focus is on: associations between insufficient and delayed sleep patterns and academic performance, with performance indicators including student GPAs and self-reported grades, test scores, time spent on homework, attendance, and tardiness.   Research addressing these questions include cross-sectional studies and a longitudinal study of school districts in various regions of the US;  results of a large study conducted in Norway (2016) that looked at the predicitive quality of sleep duration and sleep deficits on test scores was also presented.   

In addition to reporting results of studies on overall student measures of academic performance, Dr. Wolfson also discusses studies that explored several sub-topics of the issue:  a study that compared student test scores in the same core course taken in the first period versus later in the day; an experiment that compared the test performance of students who were well-slept compared to students who were sleep deficient;  research data that addressed whether students at the lower end of the distribution of academic performance benefit more or less from later start times than those at the higher end of the distribution; studies that looked at next-day academic performance when students sacrificed sleep in order to study more than usual.
