About the Study
Study Background
For industries that rely on people working at all hours, like health care, industrial plants, aviation, and the military, preventing human error due to sleep loss is essential to safety. The purpose of this study is to learn about how sleep deprivation affects the brain, its performance, and its alertness.
To do this, we will compare the effects of caffeine and the medication modafinil on cognitive performance during sleep deprivation. During this in-laboratory study, participants will spend 4 days and 3 nights in a lab (monitored by trained staff), and complete computer tasks and simulations to test their brain performance. For part of that time, participants will be kept awake while receiving capsules containing caffeine, modafinil, or a placebo.
The information gained from this study will ultimately be used to help prevent human error due to sleep loss during around-the-clock jobs. Further research today and join our compensated study!

Additional Information
The purpose of this research study is to evaluate how caffeine and modafinil can affect cognitive performance during 38 hours of total sleep deprivation.
You may qualify for this study if you meet the following criteria.
Key Criteria:
Key Criteria:
- 18-40 years old
- Regularly sleep 6-10 hours per night
- Non-smoker
- No major medical or psychiatric conditions
- Not currently taking any medications (birth control is OK)
Once enrolled, this study involves:
- First screening session (4 hours): questionnaires, blood & urine samples, breathalyzer test, driving simulator
- Second screening session (4 hours): physical exam, psychological questionnaires, driving simulator, target practice in a simulated range
- Pre-experimental phase: maintain a regular sleep schedule at home; monitor your sleep, meals, physical activity, and bowel movements; refrain from napping, alcohol, caffeine, tobacco, or drug use
- Laboratory phase (72 hours): you will stay in the sleep laboratory of the Sleep and Performance Research Center. You will not be able to access the internet, live TV, or have visitors. Most of your time will be scheduled for you and will include performance testing (computer tasks, driving simulation, target discrimination task). During part of this phase, you will stay awake for 38 hours and will receive 4 capsules that contain caffeine, modafinil, or a placebo.
- Follow-up session: about 3 weeks after completing the study, you will receive payment for your participation and a follow-up questionnaire to complete.
Compensation of up to $1000 is provided for your time.
There is no cost for you to participate in our research study.
