LRC Recruiting Daytime Participants for Paid Study Investigating the Alerting Effects of Light

The Lighting Research Center (LRC) is recruiting participants over 18 years old for a paid study that will take place over the course of four weeks, one session each week.
The studies will be held weekdays (Monday-Friday) from June 25 to August 3, 2018. Participants may choose the day of the week they wish to attend.
The study will 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.
Participants need to attend all four scheduled sessions, unless they decide to withdraw from the experiment. In order to be eligible to participate in the experiment, participants need to have regular bed times no later than 11:00 p.m. and wake up no later than 8:00 a.m. 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 the actigraph data shows that the sleep schedule was not followed, the participant will not be allowed to continue in the study.
For each session, participants will arrive at the LRC at 1:00 p.m. and electrodes will be placed on the scalp. EEG is a non-invasive, safe procedure to record brain activities. In order to obtain good electrode connections, it is necessary to clean small areas of the skin with wet cotton and apply a water-soluble paste to attach the electrodes. The study will begin at 2:00 p.m. and will be conducted for two hours. Three EEG measurements will be collected during the first hour. Each collection will last for three minutes; during this time the participants will place their chin into a chinrest, fixate on a mark, and hold still. At the end of EEG collection, 35 minutes of computer based performance testing will be started.
One week prior to the start of the experiment, participants will come into the LRC for a one-hour training session during regular business hours (i.e., 9:00am-5:00pm) and are given an actigraph to wear.
Exclusions: Persons cannot participate in the experiment if they have any major health problems or are colorblind. Persons will not be eligible to participate in the study if they are taking any prescription medication (except for birth control pills), if they are night shift workers, or if they will be traveling more than one time zone the month before or during the weeks of the experiment.

Participants will be paid $45 for each session. Payment will be processed by Rensselaer after each session. If a participant is not a U.S. citizen, taxes will be withheld from payment. Persons interested in participating in the study should contact Madison Laks at or (518) 687-7112 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 solid-state lighting, light and health, transportation lighting and safety, energy efficiency, and plant pathology. 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. With 35 full-time faculty and staff, 15 graduate students, and a 30,000 sq. ft. laboratory space, the LRC is the largest university-based lighting research and education organization in the world.

About Rensselaer Polytechnic Institute
Rensselaer Polytechnic Institute, founded in 1824, is America's first technological research university. The university offers bachelor's, master's, and doctoral degrees in engineering; the sciences; information technology and web sciences; architecture; management; and the arts, humanities, and social sciences. Rensselaer faculty advance research in a wide range of fields, with an emphasis on biotechnology, nanotechnology, computational science and engineering, data science, and the media arts and technology. The Institute has an established record of success in the transfer of technology from the laboratory to the marketplace, fulfilling its founding mission of applying science "to the common purposes of life."
