The NRLC Primary Research Area is located on the second floor (entry level) of the University Plaza Building. This area was designed to efficiently accommodate the needs of our diverse studies as well as provide a comfortable, safe, and private environment for study volunteers, since this is where they spend the majority of their time. The Primary Research Area is divided into two separate sections: the Green Zone and Blue Zone. These two areas allow us to separate study participants in different study protocols, while allowing study staff easy access from one zone to another. For example, in our laboratory, studies with children are separated from studies with adults. These two zones provide flexibility to assess participants of all ages in studies that last from a few hours to a few days or weeks, and event studies that require multiple assessments across several years. The Green Zone includes a check-in area, two waiting areas, two interview/testing rooms, and four behavioral assessment rooms. The Blue Zone includes a check-in area, three waiting areas, an interview room, six behavioral assessment rooms, and a room for medication or other pharmacological administration. Both zones include areas for study staff to monitor study participants, and to collect, analyze, and store data. The NRLC Primary Research Area occupies 3,800 square feet of space.
