The Caltech Brain Imaging Center is located at the corner of Wilson Avenue and Del Mar Avenue at the North West corner of the Caltech campus. The address is:

California Institute of Technology

After you enter the Broad Center, please take the elevator to the basement and exit left out of the elevator. You will see a set of locked double doors with glass windows (labeled 2 Broad Center) that lead to the Imaging Center. To the left of the doors is a telephone. Please dial x5858 and we will come get you.
Parking: You can park on the roof of the Holliston Parking Structure at 370 S. Holliston (see map) and obtain a permit from the security office right at the entrance on the first floor of the parking structure. If asked, say that you are a subject for the Camerer Lab.

There will be a base show-up fee that you will be paid at the end of the experiment. That amount was specified in the initial recruiting ad.
Since these experiment will be decision making studies, additional payment beyond the show-up fee varies. Your final total payment will depend on the decisions you make during the experiment. Detailed information about payment will be given to you before the experiment in the instructions that you will receive.
