Loading randomizations initially
Hi,
Following up on this question https://forum.cogsci.nl/discussion/6320/avoid-same-type-of-item-twice-in-a-row-in-loop and randomization of items within loop items in general,
I found that when running my experiment it takes at least 30 seconds for the loop items to create the pseudo-randomized order for the running session. Having multiple loop items combined into one experimental file, this leads to a few unwanted waiting periods.
Is there any way to specify that all loops contained in an experiment should create this pseudo-randomized order initially, i.e. when starting the session?
Thanks in advance,

Hi Schmit,
I have never tried that but I doubt that this is possible. Generally, it helps to have shorter loops. So if you can see yourself shortening your loops, your delay might shrink to an acceptable level.
What you can also try, is accessing the loop items directly and prepare them all at the beginning of the experiment, which would shift the entire delay to the beginning of the experiment. The
prepareandrunfunctions described here will be useful for that. But again, I haven't tried it myself, and don't know whether simultaneously preparing multiple loops could have some unwanted side effects.Does that make sense?
