Participants are told that a card will be drawn at random from the playing cards (2, 5 and 8). They then place a bet as to whether the second card will be higher or lower than the first. The first card appears on screen. It is followed by a word. The second card is then presented on screen. Finally, the participant must indicate whether or not they have won the bet. In order to control the number of trials per condition, the probability of winning and they outcome are pre-determined on each trial but the cards that are shown are adjusted depending on the participants bet. For example, imagine that the reward probability is 0.125 and the outcome is “Win” and the participant bets “Higher”. The first card shown will need to be 8 and the second card will be 9. For this same condition, if the participant had bet “Lower” the first card would be 2 and the second card would be 1.
