The main idea is to chose randomly the order of blocks from a set of 4 different block within an experiment. In the end all block should have been presented. Every block contains two trails (one audio file and a set of three items). Again, all audio files and items should be show. So it's really only about the order of the blocks.


I tried to use the noreplace on a block-level. As a result, one of the three items from both blocks are chosen and the others won't show up. Am I wrong to use noreplace in this case?


<expt>
/ subjects = (1 of 2)
/ blocks = [1-4=noreplace(A1, A2, A3, A4)]
</expt>

<expt>
/ subjects = (2 of 2)
/ blocks = [1-2=noreplace(B1, B2, B3, B4)]
</expt>


Thanks a lot!

To add: You very likely have *mistakes* in your script that make you *think* a certain block is repeated.

What could those mistakes be?

#1: You have <block>s that run the wrong <likert>, i.e. something like

<block blockp5>
/ trials = [1=person_3]
</block>

#2: You have <likert>s that display the wrong <picture>, i.e., something like

<likert person_5>
...
/ stimulusframes = [1= pic_3, cue1] 
...
</likert>

and/or

#3: You have <picture>s that display the wrong item

<picture pic_5>
...
/ items = ("3.jpg")
...
</picture>

Go through it and see if you can spot anything along the lines outlined in the previous reply. If you can't find any (or all of the) mistakes and need a second pair of eyes, attach the script file to this thread (click +Insert -> Add File) and I'll be happy to take a look.
