Can lighting help you find your flow?
Wright State University researchers are studying how controlled warm and cool room lighting affects focus, flow, and alertness during everyday mental work.
What will I do?
You will attend three study visits on different days. Each visit will last approximately 90 minutes:
- about 20 minutes to adjust to the room lighting;
- 60 minutes to complete your own moderately difficult paper or e-ink work without a light-emitting screen; and
- about 10 minutes for brief paper questionnaires.
During each visit, you will wear one or more small, noninvasive research sensors. Depending on the device setup, a sensor may be worn on your wrist or placed on the skin at a finger, ear, or wrist. The sensors may record body signals such as pulse, skin conductance, skin temperature, blood-oxygen estimates, or movement. These are research tools and do not provide a medical diagnosis.
Who may take part?
You may be eligible if you:
- are age 18 or older;
- regularly do focused mental work such as studying, reading, or writing; and
- can attend three daytime visits on different days.
You cannot take part if you have color blindness, a diagnosed sleep disorder, regular beta-blocker use, sensitivity to bright light (including light-triggered migraines), or a history of light-triggered seizures.
When and where are visits?
Visits take place at Wright State University and are generally scheduled between 10:00 a.m. and 4:00 p.m. You will be asked to avoid light-emitting screens for at least two hours before each visit and to avoid caffeine and other stimulants on the day of each visit.
Is there payment?
No. Participation is voluntary, and there is no direct benefit to you.
