Recruiting: Nighttime Participants for Paid Study Investigating Alerting Effects of Light0

The Lighting Research Center (LRC) is recruiting persons over 18 years to participate in a study that will take place over the course of five weeks, one session each week.
The weeks of the study are January 14, 21, 28 and February 4 and 11, 2019.

The study will take place on Tuesday, Wednesday, Thursday, or Friday of those weeks. 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 5 scheduled sessions, unless they decide to withdraw from the experiment. 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 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 10:00 pm 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 11:00 pm 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 and are given an actigraph to wear.
