OSWeb randomisation behaves differently

DionH

Hello,

I'm using shuffle_horiz to randomise the locations of some probe items on each trial. This works perfectly on my computer, however, when I move the experiment online the randomisation is done only once at the start, and then those positions are fixed for the rest of the experiment. Here is the experiment file:

DistTemp_question.osexp

You can see that within the block loop I have used shuffle_horiz to randomise the "stim" locations, and within the trial sequence there is a probe_loop where I have used shuffle_horiz to randomise the "probe" locations. The stim locations successfully shuffle on every presentation, however the probe locations shuffle every presentation only when I run it locally.

If there is any way to fix this then I would appreciate the help, otherwise any tips for how I should reorganise the structure to achieve what I need would be great too.

Thanks!

I have changed the way the experiment works in order to avoid this problem. Thanks.
