In order to participate in experiments at the Wichita State Behavioral Economics Laboratory, you must follow the steps and register. Part of this process involves acknowledging the following rules of conduct:

• You can only register once in the database.
• You must bring your unexpired Wichita State University ID card to each session, so that our researchers can verify your status.
• A certain number of registered persons will receive an invitation email to each experiment. Only the invited persons may take part in that experiment.
• If you receive an invitation email, you must respond affirmatively in order to participate. Spaces in an experiment are limited, so it is important to respond early to better ensure that a space will still be available.
• Once you respond affirmatively, you cannot later withdraw this response from the recruitment system, so please verify that you are actually able to come before you respond.
• Usually, some extra persons are invited to ensure that a minimum participation level is achieved. Alternates will receive $5 compensation for arriving for the experiment on time.
• Participants will usually be compensated based on the decisions they make during the experiment.
• After the scheduled start time, anyone who responded affirmatively to an invitation but did not show up will not receive any compensation for that experiment. In addition, after a person receives 4 no-show emails, he or she will be ineligible for any further experiments.

Wichita State Behavioral Economics Laboratory's research-ethics responsibilities include the proper safeguarding of potentially sensitive data collected during an experiment. We take the following steps to meet its confidentiality requirements:

• All data collected during recruitment is stored on a server that is accessible only to the laboratory research staff. These data are used only for the purpose of recruiting subjects to participate in our experiments.
• All personally-identifying data collected during an experiment (e.g., your name) is processed according to the approved ethics document of the respective study. Usually, any personal information is replaced with a code number, and the list linking code numbers to personally-identifying data is kept separate from the experimental data.
