Random picture selection Visual World Paradigm

Ahorn_siroop

Noob question.

I have followed this tutorial on the visual world paradigm.

When I test run the experiment, the images and sounds are shown randomly, instead of one row making up the media for one trial. Everything is exactly the same as in this tutorial. I don't have full-factorial design selected, and I could not find any other potential causes of this.

How do I make sure that one row constitutes one trial?

Hi @Ahorn_siroop,

First of all, you might want to use the latest version of OpenSesame and therefore read the latest documentation: Visual world // OpenSesame documentation

Second, I am not quite sure I understand what the problem is here; what do you mean by "the images and sounds are shown randomly instead of a row making up the media for a trial"? Do you mean that you get some sort of random combination (picture2 from row1 with picture3 from row3, etc.)? 

If this is the case, and if you have followed the tutorial to the end, you will have been asked in Step 4 -> Distractors to add shuffle functions. This is what this function does: it shuffles the values in your table vertically (i.e., between rows).

If you do not want this behaviour, you can remove them:

1) Click on 'view script'

2) Delete those rows

3) Click 'Apply' and run again.

Does this solve your problem?
