The Lighting Research Center (LRC) is recruiting subjects over the age of 18 to participate in a study that will take place over the course of four weeks, one session each week. The weeks of the study will be: January 27, and February 3, 10 and 17. The study will take place on either Tuesday, Wednesday, Thursday or Friday of those weeks. Participants can choose the day of the week they wish to attend. The experiment will run both in the afternoon and at night and you can choose to participate in the afternoon session or the nighttime session. Participants will need to attend all four scheduled sessions, unless they decide to withdraw from the experiment.
The goal of the study is to investigate the alerting effects of light by measuring brain activities under different light exposures using Electroencephalogram (EEG) and through various performance tests done on a computer.
In order to be eligible to participate in the experiment, participants need to have regular bed times no later than 11:00 pm and wake up no later than 8:00 am. This regular schedule must be kept throughout the study. Participants will be asked to wear an actigraph and keep a sleep log all the weeks of the study, starting one week before the study begins. If your actigraph data shows that you have not followed the sleep schedule, you will not be allowed to continue in the study.
For each session, you will arrive at the LRC one hour before your scheduled session begins for EEG setup. EEG is a non-invasive, safe procedure to record brain activities. The afternoon sessions will begin at 2:00 PM and the nighttime sessions will begin at 11:00 PM. Each session will run for 2 hours. During these two hours you will have EEG data recorded and will complete several computer based performance tests.
One week prior to the start of the experiment, during the week of January 20, participants will come to the LRC for a one-hour orientation and to receive an actigraph.
You will not be eligible to participate in the experiment if you have any major health problems or if you are colorblind. You will not be eligible to participate in the study if you are taking any prescription medication (except for birth control pills) or if you will be traveling more than one time zone the week before or during the weeks of the experiment.
Participants will be paid $75 for each session – a total of $300 for completing all four weeks of the study. If you are not a U.S. citizen, taxes will be withheld from your payment.
