How can I implement pseudo-random selection from a list?

[Tobias]

Dear all,

again a rather elementary issue stroke me when I was testing a new
paradigm. When I have four target types, it often happens that one of
them is used 10 times in a row. Let's not discuss how random E-Primes
"random" is (I don't really trust it!). But: How can I implement a
pseudorandom selection from a list?

Let's say I want E-Prime to choose randomly trials from a list, but
one of the four target types must not be repeated more than twice in a
row.

I didn't find anything like that in the options, maybe some code
helps. Has anyone of you ever tried to do such a thing?

Looking forward to reading your answers!

Best,
Tobias

Tobias,

This has been discussed at length time and time again both in this
Group and on the PST Forum (including this very week). Did you try
doing a search for this topic on the discussion groups?

Yeah, I tried antering "pseudorandom" but there weren't any helpful
discussions. And no recent ones, especially.

Didn't look at the PST forum

[Tobias]

okay, if i enter "pseudo-random", I find it. Let's discuss it there
and close this branch.

Tobias,

If you widen your search to simply "random", you might find even more
useful discussion.
