In this study, you will participate in two different games, and you will play each game for 40 rounds. Each game has two different roles: Player 1 and Player 2. In each game, the computer will randomly assign you one of these roles, and you will be assigned to this role throughout all 40 rounds.

Before each round, the computer will randomly pair you with another participant who was assigned the role of the other player. This participant will be your partner for that round of the game. You will not be paired with the same partner in two consecutive rounds

In each round, you and your partner will each make a single choice. The choices you both make will determine your payoffs for that round. The possible choices and the potential payoffs in each round of the first game are presented in the tree figure below:

In each round, Player 1 must choose between HEADS and TAILS and Player 2 must choose between LEFT and RIGHT. The “leaves” of the “game tree” represent the possible payoffs in each round. The payoffs of Player 1 are presented in blue, and the payoffs of Player 2 are presented in orange. Note that Player 2 makes a choice in every round, regardless of Player 1’s choice.

Specifically:

1. If player 1 chooses TAILS, then player 1 will {{ session.config.p1_tails }} points with certainty, and player 2 will {{ session.config.p2_tails }} points with certainty (regardless of player 2’s choice).
2. If player 1 chooses HEADS and player 2 chooses LEFT, then player 1 will {{ session.config.p1_left }} points with probability {{ session.config.p1_left_prob }} and {{ session.config.p1_left_otherwise }} points with probability . Player 2 will {{ session.config.p2_left}} points with certainty.
3. If player 1 chooses HEADS and player 2 chooses RIGHT, then player 1 will {{ session.config.p1_right }} points with certainty, and player 2 will {{ session.config.p2_right }} points with certainty.

The game tree presenting the possible payoffs will be presented on the screen for the entire duration of the game.

In each round, you will have {{session.config.timeout_seconds}} seconds to make your choice. To make a choice, you will need to first select your choice and then press the "Next" button. If you time out, you will not get any payoff for the round. If you time out 3 times, you will be removed from the experiment.

After you and the other player make your choice, you will see your payoff for that round. In addition, you will see the payoff you would have gotten had you chosen differently. Lastly, you will see the choice your partner made.

At the end of game 1, you will continue to game 2, which will be similar but will have a different payoff structure. Instructions for game 2 will be given later.

At the end of both games, the computer will randomly pick one round from all rounds in the experiment. The payoff you obtained in that round, plus an endowment of 100 points, will serve as the basis for your bonus payment in this study. Each point is worth £{{session.config.real_world_currency_per_point}}.

Since this a multiplayer game, you might have to spend some time waiting for other players. {{session.config.expected_wait_time}} seconds are included in the show up fee. For any additional time you spend waiting to be matched with other participants, you will be compensated at a rate corresponding to an hourly wage of {{session.config.waittime_wage}} GBP.
