This study is part of a scientific research project conducted by the Chair of Computational Psychology at LMU Munich. Your decision to complete this study is voluntary. We will only have access to your worker ID and no other information to identify you. The only other information we will have, in addition to your response, is the time at which you completed the survey and the amount of time you spent to complete it. The results of the research may be presented at scientific meetings or published in scientific journals. Clicking on the 'SUBMIT' button on the bottom of this page indicates that you are at least 18 years of age, and agree to complete this study voluntarily.

In this study, you will play 4 rounds of a simple card game. In each trial, you'll be randomly given two cards. One card will be visible to you, and the other will be hidden. You will have the choice to stay and keep the points in the card that is visible to you, or switch and take whatever points are in the hidden card.

Each round will consist of 28 trials of the card game, for a total of 112 trials. Completing the full study should take 20-30 minutes. Please pay close attention to the instructions and answer ALL questions to the best of your ability. Thank you for contributing to a better understanding of how the mind works!

In this study, you'll be playing a simple card game.

There are {0} cards total, and each card is worth a different number of points. Your task is to get the most points by the end of the game.

Can you click the {1} card?

In each trial, we'll randomly choose 2 cards from this pile.

You'll be able to see one card, but the other card will be hidden from you. You can choose to stay with your card, and get the number of points in your card, or to switch, and get whatever points are in the other card.

Press the Z key to {0}, and the M key to {1}.

Try it now! Whatever card you select will be highlighted. In the task itself, pressing a key will end the trial. Here, press the continue button when you're finished testing out the controls.

Important!

Let's add another player to the game. This is your advisor, Alice.

Alice cannot see the card that is face-up to you. She can only see the hidden card.

Based on what's on the hidden card, she will suggest whether you should stay with your own card, or switch and take the hidden card.

However, she will be given some extra information about your card. Based on this, Alice will suggest whether you should stay with your own card, or switch and take the hidden card.

Before we begin...

We'd like to ask you a few questions about Alice.

One more thing...

Now that you've finished the main task, we'd like to ask you a few questions about Alice.

Did you find Alice's advice helpful?
Please tell us what you thought about Alice and whether you noticed anything about her as you played the game.

Please write down a comment to continue.

In this question, you'll take on the perspective of Alice.

Suppose that Alice looks at the hidden card and finds this:

Stay

Switch

+{0}

What are the chances that Alice will tell you to switch?
Remember, you're taking on the perspective of Alice. If Alice tells you "switch," she is telling you to take the card above. If Alice tells you to "stay," she is telling you to keep the card you can see instead.

0%
(Definitely "stay")
100%
(Definitely "switch")

Please adjust the slider before continuing.
