1 in a cell in the data file: left choice
0 in a cell in the data file: right choice
Example
In the data file, on the first page, subject 14 (see column) in choice pair 4.3 (see row) has a 0. What does this mean? Page 1 of the data file means it concerns the Prince experiment. To see what choice pair 4.3 is, we take the above link to the file with the choice pair nrs, and find out, on p. 4 there, that it is a choice between a left lottery
(0.25: 10, 0.25: 5.25, 0.25: 4.20, 0.25: 0.30)
and a right lottery
(0.25: 6.75, 0.25: 5.85, 0.25: 3, 0.25: 2.70)
The 0 means that the latter, right, lottery was preferred by subject 14.
