4-way forced choice

Hello All,

I'm doing some vision research. My experiment involves partitioning a screen into 4 quadrants of equal size and from that, getting user input based on various criteria. The user would select one quadrant, and then after that, the stimuli would change. I'm looking to use a 4-way forced choice model. I'm told using Quest may be of some use? Please forgive me if these questions seem a bit novice as I'm not an specialist in the field and am doing some Matlab coding for professors.

If anyone has any tips/points, I would really appreciate them!

Thanks,

Arthur
