On each trial, you will see two gambles, side by side. Your task again is to judge how much more you would like to play the gamble on the right compared to the gamble on the left; that is you are to judge the DIFFERENCE between the gamble on the right compared to the gamble on the left.
Use this DIFFERENCE scale as follows:
10% from left = Like the LEFT gamble very much more
20% from left = Like the LEFT gamble much more
30% from left = Like the LEFT gamble more
40% from left = Like the LEFT gamble slightly more
50% from left = Like both gambles EQUALLY (middle of line)
60% from left = Like the RIGHT gamble slightly more
70% from left = Like the RIGHT gamble more
80% from left = Like the RIGHT gamble much more
90% from left = Like the RIGHT gamble very much more
So, the more you like the gamble on the Right, compared to the one on the left, the farther your mark will be to the right. If you would like them equally or they are the same, you should click in the middle of the scale. If you like the left one better, your click will be left of the middle, and the more you like the left better, the farther to the left your mark should be.
