The Decision-Making task. Participants were first told the amount of money at stake (e.g. £150) and were told that they could never keep all of the initial stake. They were then presented with a sure option (framed as a gain or loss of a fraction of the money at stake, e.g. keep £100 or lose £50), and a gamble option (with a pie chart representing the odds of winning vs. losing all the money at stake). In the experimental trials the utilities of the sure option and gamble option were equal. Participants completed the task once for themselves (panel A) and once for an unknown other participant (panel B) with the wording of the framing reflecting this change in perspective.
