Instructions Task {{Constants.tasknumber}} - The Grid Task


{% endblock %} {% block content %}

Remember that for the entire experiment you have been randomly assigned to be the {{ player.role }}!

  • Each Decider is randomly paired with another Performer before every round.

  • The Performer will be shown 10 matrices (5x5) containing 0es and 1s for 45 seconds. The Performer will have to count the number of 1es for each matrix and type the answer down.

  • One example of such matrix is:

  • 0 1 0 0 1
    1 0 0 0 1
    1 1 1 0 1
    1 1 1 0 1
    1 1 1 1 1

  • Each Decider will then get assigned to a lottery. The number of correct grids solved (and written down) by the Performer determines the lottery that gets assigned to the Decider. This lottery leads to either one of two outcomes (high and low) but with differing probabilities.

  • A refresher on lotteries - What is a lottery? For example, the following lottery: ₹0 with 20% probability or ₹500 with 80% probability - means that there is a 20% chance that the Decider wins ₹0 and an 80% probability that Decider wins ₹500. Alternatively, think of a lottery as a 10 sided die. In this example, the die has 0es on 2 sides, and 500s on 8 sides.

  • Each grid solved correctly by the Performer increases the probability of higher earnings for the Decider. For example:

  • Number of correct answers by the Performer Lottery earned by the Decider
    0 correct answers with 20% probability the outcome is ₹500; with 80% the outcome is ₹0.
    1 correct answer with 30% probability the outcome is ₹500; with 70% the outcome is ₹0.
    2 correct answers with 40% probability the outcome is ₹500; with 60% the outcome is ₹0.
    And so on.

  • Once the time has passed (of 25 seconds), the Performers will not be able to solve no more grids, and the Deciders will get to know their earnings from the lottery.

  • Each Decider will then choose the payment for the Performer. The Decider makes the payment from a separate amount of money of ₹350. He/she has to divide this amount between his/her Performer and a randomly chosen Performer from the room. Any unassigned money will go back to us and therefore will NOT be kept by the Decider.

  • Payment Rule for Each Round


  • So the earnings for each round is as follows:

  • Finally, you will be asked some further questions.
