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!

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>

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.
