Decision-Making Experiment: Instructions, Informed Consent, and Warmup

This is an experiment on judgment and decision making. You will be asked to read descriptions of situations and to respond via the computer to indicate your judgments. This study poses no more risks that those of being a college student in a nation with freedom of speech and freedom of the press. You will be asked to think. The study has two purposes: to better understand how people make decisions and to educate students by providing them an example of a research study in psychology. You need not participate. There are other studies that you can do and other assignments that you can substitute instead of this one. You need to make two decisions: Do you want to participate? and Do you want credit toward the assignment in Introductory Psychology? If you agree to participate, you agree that your data may be used by researchers who might publish statistical summaries of data. We do not divulge the names of participants, but realize that your data are no more secure than e-mail. Therefore, you should respond as if you were sending e-mail. Although unlikely, the FBI or department of homeland security might be monitoring the data transmissions, so please do not make terrorist threats or send other communications that will require police action.

IF YOU WANT CSUF CREDIT toward your class assignment, you will need to follow the instructions carefully. We will NOT assign credit for cheating. (Some students think that the best way to complete the assignment is to simply push buttons like a robot and thereby get credit without learning anything.) In this study, however, NO CREDIT will be given toward your assignment if you cheat. Do not ask to receive credit in your psychology class for any form of cheating. Visitors who do not want CSUF credit are welcome to do as much or as little as you like.

IF YOU WANT CSUF CREDIT: We will need for you to enter your identifying information including name, ID number, and email address where requested. We do not sell or share this information, but realize that this information is being sent via the Internet without any more security than email. You will also be asked to spend the amount of time on the study for which you request credit. If you want 2 hours of credit, you will be required to work at the task for 2 hours. If you want credit, you must read the instructions carefully and carry out the task as if it were a homework assignment or take-home exam in a college course. If you cannot follow these rules, or don't understand the task, please do NOT do this study and then ask for credit.

If you would like CSUF credit, please enter the following information:

INSTRUCTIONS:

Look at Choice No. 1 below. Imagine two containers, each of which holds exactly 100 tickets. The tickets are all identical, but they have different cash prizes printed on them. You get to choose the container from which a ticket will be drawn randomly. You win the amount of money printed on the ticket.

The first gamble in Choice No. 1 has 50 tickets that win $100 and 50 that win $0, so the probability to win $100 is .50 and the probability to get $0 is .50. If someone chooses the First Gamble, half the time they will draw a ticket that pays $0 and half the time they will draw a ticket to win $100. But in this study, you only get to play a gamble once, so the prize will be either $0 or $100.

The Second Gamble has 100 tickets also, but 50 of these win $25 and 50 of them win $35. The second gamble thus guarantees at least $25, but the most you can win is $35.

Some people will prefer the First Gamble and some will prefer the Second Gamble. To mark your choice, click the button next to First or Second Gamble. Notice that the dot next to No. 1 will empty and fill in the button next to your choice.

On December 24, 2007, after people have finished their choices, three people will be selected randomly to play one gamble for real money. One trial will be selected randomly from all of the trials, and if you were one of these lucky people, you will get to play the gamble you chose on the trial selected. You might win as much as $100. Any one of the choices might be the one you get to play, so choose carefully.

IF YOU WANT CREDIT: Please do the entire task in one sitting in a setting in which you will not be distracted and you can think. Make your choices carefully. Many of these choices have no "right" answer, but in some choices, there is a correct answer. We will check if your answers are random on such choices, and we will also record the time for each choice. If your time is too fast for a person to make a reasoned decision, the server will NOT warn you, but you will receive no credit. Because we are studying the time required for each decision, we ask that you do not leave the study in the middle and come back later, but do it all in one setting, as you would take a final exam.

If you enter random responses, you will not be warned (except in this warmup), but you will receive no credit. To get credit you are required to complete all parts of the experiment and to serve for 2 hours. If you complete all parts of the study in less than 1 hour and 55 minutes, you should start again with part 1 and work through the study until you have spent 2 total hours. If you do not understand the task, you should find another study to do or complete the alternate assignment. Your data will be checked by both computer and by a human and you will receive credit within 48 hours of the END deadline of the session for which you signed up. You will receive an automated reminder before the deadline even if you have completed the task.

Please check to make sure that you have answered all of the Questions. Scroll up and check that there are no dots next to the numbered questions.

CSUF Students: You will receive no further warnings about skipped items, random responding or the timing of your decisions (e.g., responding too fast or taking a break--neither of which you should do). If you do not think you will be able to follow the instructions for two hours, please do not go on to part 1. No credit will be given toward your class assignment for mindless button pushing. Your data will be checked by both computer and a person before credit is assigned.
