  1. After the main slot machine task, ‘tickets’ paid out by the machines were presented to the participant again. The participant was asked to recall two specific details associated with the ticket: the machine that paid it out (left or right) and the value of the ticket (−$5 or $5). To encourage participants to encode the ticket-machine-value triplet, they were told that the final value of the tickets would depend on both the original value of the ticket and the participant’s performance on two post-task recall questions. If they answered either question incorrectly, $5 tickets were modified to be worth $0. If they answered both questions correctly, −$5 tickets were modified to be worth −$2.5. The payout values of each ticket after the memory tests are described in this table. Values altered by the results of the memory tests are highlighted in bold.
