Sleep consistency, cortisol, and cognition: 14- to 16-year-olds
Teenagers sometimes sleep in as late as 4 hours on weekends. When you think about it, that'd be like flying round trip from New York to Los Angeles every weekend! No wonder teens are often referred to as "chronically jetlagged." Jetlag in adults has been linked to problems with memory and cognition because of an increase in the stress hormone cortisol. In addition to making us feel more awake, cortisol can interfere with normal memory at high levels. So it seems like an important question to ask, "How does sleeping in change teenagers' cortisol levels, and is this change enough to interfere with daytime functioning?"

Subjects in our studies commit to only 10-15 minutes of sampling, surveys, and computer games for 8 days, all from home. You never need to come to our lab! We just set up a training session with the teen and their parent and they run the entire study from the comfort of their own home. Subjects are also reimbursed for their time and participation.
