Hi all,
I have some experience with the E-Prime GUI, but little programming experience, and I would very much appreciate the board's help in helping me with some design questions. I am trying to set up an experiment on preference in which subjects pick between two options (each choice has two parameters) in each trial. Based on participant choice in one trial, parameters of one option of the two should change.
Example: option 1 has parameters X1 and Y1, and option 2 parameters X2 and Y2. Subject selects option 1, which results in option 2 being assigned new parameters: X2 & Y3, and the subject is again asked to choose between the two. If option 2 is now selected, parameters of option 1 change to X1 and Y4, etc.
I tried to experiment with "if-then" commands, but the only way I saw was to finitely define all possible choice patterns, and I am sure that there is a better way. I am not very familiar with nested lists, but if they are the answer, please let me know how that would work.
Hope this is clear enough. If not, please ask for clarification.
Best,
Siggi
