Millisecond Forums

Hi,

I'm intending to show my participants a number of stimulus blocks in randomized order. After each of these stimulus blocks, I want to start another block containing survey questions specific to the stimuli presented in that block, and then select another randomized stimulus block to continue, and so forth. How would I implement this? It cannot be done inside <expt> since the order of the blocks must be randomized.
I currently have this, which doesn't work.

<block Jantje1>
/ onblockend = [values.stopblock=0; survey.Jantje1survey;]
/ stop = [values.stopblock==1]
/ trials = [1=getstim]
</block>

note: trial getstim sets values.stopblock to 1 when the stimuli have been presented and the block must end. the survey works when called from <expt> but not when called this way. this does not work either: /branch [if (values.stopblock==1) survey.Jantje1survey] 

regards,

Sercan
