• Or are healthy with typical bedtimes and no sleep concerns

Study activities include:

• Health screening
• Monitor on separate occasions your sleep, mood, eating times for one or two weeks and blood sugar levels while living at home
• Live in the sleep laboratory on two separate occasions for 48–66 hours (approximately 4.75 days in total)
• Blood and saliva sampling and reaction time, mood and ability to think testing

Compensation is up to $1,725. Get study details and apply.

The purpose of this study is to examine how light exposure and meal timing influences circadian rhythms in healthy people ages 17–40.

Are you a first-year student at CU Boulder? Interested in a research study on stress and coping in CU students? 

The Research on Affective Disorders and Development Lab is conducting research on stress coping in first year CU students. We want to understand what helps CU students cope with stress during major transitions, including the transition to college and across semesters.

The study includes a few different parts that happen over the three-semester study period: 

1. There are two in-person research sessions, each of which takes about 4–6 hours. During these sessions, you will play some computer games while we monitor physical functioning (for example, your heart rate). You will also complete a set of interviews and surveys that ask about stress, behavior, mood and health.
2. There are three 21-day periods in which we will send you a daily “micro survey” (less than 5 minutes to answer) asking about your behavior and mood using an app.
3. There are two 1-hour online surveys that we will send to your email.

The study takes place over the course of three semesters, and you will be compensated for your participation (maximum of $446–$470 for completing all parts of the study).

If you want to learn more, contact the RADD lab at raddlab@colorado.edu or fill out our initial eligibility screening. 

Do you love listening to music? Are you curious about what music others are listening to? The Brain Music Lab at CU Boulder is currently recruiting participants for a research study investigating music listening, sharing and enjoyment behaviors in young adults (IRB # 24-0658).

Participating involves completing an online survey, followed by one visit to the Brain Music Lab (Roser ATLAS building) on CU Boulder’s Main Campus where you will listen to music, answer questions on a computer and have a short interview about your experience.

The total expected time commitment is two hours. Individuals who complete the study will be compensated with a $20 Amazon gift certificate and be entered in a drawing for an additional $50 Amazon gift certificate.

To participate, you must be between the ages of 18–25 and have normal or corrected-to-normal hearing.

Interested in participating or have any questions? Please email Sophia Mehdizadeh (some4995@colorado.edu) or complete this form.

The Pain Lab at CU Boulder, affiliated with the Institute of Cognitive Science, is seeking participants ages 21–70 for a research study with non-invasive wearable sensors.

You may be eligible if you have experienced back pain for the last three-plus months. Participants will be compensated up to $360.

If you're interested, fill out the eligibility screening form. We will contact you regarding your eligibility.

Please consider participating in our study, Advancing and Validating Galvanic Disorientation Simulation Trainer.

In this experiment, you will wear a galvanic vestibular stimulation headset. This system senses how you are tilted and stimulates your vestibular system with small amounts of electrical current through electrodes based behind your ears, near your forehand and back of your head. The system is intended to make you feel like an astronaut returning from spaceflight. During the experiment, you will perform tasks like reporting how you feel you are tilted, standing balance, walking or using a joystick to keep yourself upright in a chair.

You will be paid for the time you spend participating in this study.

If you have questions, would like additional information or are interested in participating, please respond via email. The principal investigator for this study is Torin Clark. You must be 18–65 years old to participate in this study.
