Please read this statement of consent before deciding to participate. You can contact the Sleep and Cognition Lab if you have any questions.

No special participant qualities are necessary other than being over the age of 18 and speak English. Participation in this research study is completely voluntary. Please read the information below and ask questions about anything that you do not understand before deciding if you want to participate. A researcher listed below will be available to answer your questions.

This survey is being conducted by Sara Mednick, PhD, of the Department of Cognitive Sciences at the University of California, Irvine. 

The purpose of this research project is to screen and recruit participants for the Sleep and Cognition Lab’s ongoing sleep studies.  No special participant qualities are necessary other than being over the age of 18 and speak English.  We plan to enroll 5000 participants.

This screening study involves multiple components: (1) Screening Questionnaires – You will be asked to fill out a survey that describes your views and characteristics.  The data will be collected online on this website. (2) Follow-up: You will receive a follow-up email or phone call from us that indicates the studies you are eligible for within 4-6 weeks from completion of this screening survey. (3) Lab Database - We would like to keep your information in our database and contact you about research studies you are eligible for 5 years. You can “opt out” and select a different time frame to remain in our participant system.

The screening survey takes approximately 30 minutes to complete.  You will receive follow-up communication from us in the next 4-6 weeks detailing the sleep studies that you are eligible to participate in. Your participation in this screening survey today does not require your participation in any future studies in the Sleep and Cognition Lab.  Your contact information will remain in our participant database for the total amount of time you have indicated above.

There is a potential risk of anxiety, fatigue, or embarrassment when completing the questionnaire. There may be some risks to being in this study that we don’t know about now.  However, by participating in this study, you will learn about whether you are eligible to participate in any of the Sleep and Cognition Lab’s ongoing research studies.  Our research has also helped society learn more about the relations between sleep, memory, and health. 

You do not have to participate in this study. You participation is voluntary.

If you are enrolling via the University of California, Irvine Social Science Human Subject Pool, you are eligible for one research credit upon completion of the survey. No other forms of compensation are offered. You will not be required to pay for research related procedures/treatments.
You are free to withdraw from the study at any time. If you choose to withdraw from the study or are asked to stop participation in the study, you may not be eligible to participate in the Sleep and Cognition Lab’s other ongoing research studies.

Your research records (paper/pencil and/or online survey data) will be stored in a locked cabinet, or on a password-protected computer.  Only the research team will have access to your data.

If during the course of this study, significant new information becomes available that may relate to your willingness to continue to participate, this information will be provided to you by the investigator.

If you have any questions about your participation in this study, please contact Sara Mednick at But if you have questions about your rights as a research subject, or if you wish to report any misgivings, please contact the UCI Office of Research, Human Research Protections, at (949)824-7295, or to contact them by email please do so at
