Sign up for each experiment only once. Look at the sign-up sheet to make sure that you meet any special restrictions. If someone has forgotten to do this, do not hesitate to remind them to explain the purposes and methods of the experiment to you once the experiment is over. Report any failure to do this to Professor Jacobs. We post the announcements on a bulletin board located on the 3rd floor of the Psychology Building in the Northwest section of the main hall.
Investigators post new experiments all the time so check the board regularly.
When you find an experiment that interests you, print your name and any other information asked in the spaces given. Do not add any dates, times, or other stuff to the sign-up sheet. The department does not keep these records. You are the only one who can contact the experimenters if there is a problem. Some of these experiments need you to be there more than once.
