THIS EXPERIMENT IS NOW OVER.
This is a study of decision making in which you can gamble without risk and perhaps even win some money, if you are lucky. At the same time, your participation in this study can help scientists in the Decision Research Center learn more about how people make choices. Decide first if you want to participate. You must be over 18, and each person can participate only once. Scroll down and look over the questionnaire. It usually takes about 10 minutes. Also note: Study ends and prizes awarded 09/21/99. Void where prohibited by law.
