LRC Recruiting Participants for Paid Study: Investigating the Alerting Effects of Light in a Simulated Office Environment

The Lighting Research Center (LRC) is recruiting participants over the age of 18 for a new study that will take place over the course of four weeks, one session each week. The weeks of the study will be: October 1, 8, 15 and 22. 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 or both. Participants will need to attend all 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 bedtimes 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, participants arrive at the LRC one hour before the 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 participants 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 September 23, 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 major health problems, are colorblind, take prescription medication (except birth control pills), or are traveling more than one time zone the month before or during the weeks of the experiment. 

Participants will be paid $75 for each session  a total of $600 for completing all four weeks of afternoon and night time study. If you are not a U.S. citizen, taxes will be withheld from your payment. If you are interested in participating in the study, please contact Bridget Bradley at or (518) 276-7167 for more information. Thank you! 

About the Lighting Research Center
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is the world's leading center for lighting research and education. Established in 1988 by the New York State Energy Research and Development Authority (NYSERDA), the LRC conducts research in light and human health, transportation lighting and safety, solid-state lighting, energy efficiency, and plant health. LRC lighting scientists with multidisciplinary expertise in research, technology, design, and human factors, collaborate with a global network of leading manufacturers and government agencies, developing innovative lighting solutions for projects that range from the Boeing 787 Dreamliner to U.S. Navy submarines to hospital neonatal intensive-care units. In 1990, the LRC became the first university research center to offer graduate degrees in lighting and today, offers a M.S. in lighting and a Ph.D. to educate future leaders in lighting.
