... and all 8 orderings are in attached zip.

I've attached a zip with 4 different randomized pairings/orderings for this task . We are planning to produce 4 more, but unfortunately, they won't be ready until next week when Katja (the script developer) returns from vacation.

Hi
I was wondering if any progress had been made on getting a randomised version of this test? My study starts in less than four days and I am starting to worry.
Thanks
Alex

My participants will be taking the test 53 times.

We're looking into randomizing the Digit Symbol Task. To avoid learning effects, we're thinking it's best to vary not only the digit-symbol mappings but the order of symbols in the matrix. Towards that end, it would be easier for us to simply create N variations of the script with different mappings and orders, and as it turns out, we already have these in hand anyway. How many times will your participants be taking this test?

The OSpan is randomized -- only the practice trials are "fixed", i.e. always the same, and are supposed to be. If that's not what you mean, please clarify. Thanks!

Thank you very much. Is it possible also to get a randomised version of the OSpan task? My study starts two weeks from today and if you could help me out with this it would be greatly appreciated.
