Forced Choice & Pairwise Presentation

[darwin1867]

Hello,

I was wondering how to create an experiment that presents images pairwise on the screen, together with a questions (e.g. Which face do you think is more attractive?).

Is there a way that the subjects can click on the images for providing their statements (or at least on buttons below the images)? Could the faces be randomly chosen from a certain "images" folder, or do I need to create maps with all combinations of pairs in an imaging program (or Powerpoint) and tell Medialab to randomize these maps/slides?

Any experiences and/or suggestions about how to figure out such "forced choice" design will be highly acknowledged!

MediaLab allows you to enter image names in place of text labels for scale responses. So you could just use a 2-point scale response, each with an associated image in place of the usual label. You can resize and position the buttons anywhere you like. There is a zipped sample that illustrates this in the second sample folder (the last item believe). If you try it, let me know if you have any trouble with it.

Thanks much for your help! I will try and see if I get things running. Best wishes, B.
