Current Research:

Project Name: Sleep and Development

Duration: 06/01/01 through 05/30/05

Website: www.sleepforscience.org

Information:
Participants (ages 9 or 10 years, 15 or 16 years, and 21 or 22 years) are needed for a study of sleep patterns, sleep structure, and sleepiness. Interviews of parents and participants determine qualifications for the study, which is examining the impact of parental alcohol history and child alcohol use (if any). The study requires careful record keeping and sleep/wake scheduling for about two weeks, visits to the lab for an evening and an entire weekend (nights and days) for testing, including sleep monitoring and daytime tests of performance. Participants and parents receive financial compensation.
