Dear all,

I would like to test which product participant would choose if there have two options. In the test they need to decide between two products which are demonstrated by pictures. Can you recommend a suitable script where options can be images? 

Kind Greetings,
Nivong

You should not need some elaborate example script for this. Define the two <picture> elements, have your <trial> display them per its /stimulusframes or -times, set the trial's /inputdevice to mouse and define the names of the two picture elements as your /validresponse.

<picture productA>
...
/ position = (35%, 50%)
</picture>

<picture productB>
...
/ position = (65%, 50%)
</picture>

<trial choicetrial>
/ stimulusframes = [1=productA, productB]
/ inputdevice = mouse
/ validresponse = (productA, productB)
</trial>
