Pseudo-randomising trials in e-prime

[Ben Robinson]

there is an example given on the e-prime website, in the users' section.  you will need a password to enter, but it costs nothing to register for a password.

Investigators here have asked me this question, too. For example, if 
we're showing people images and words and we don't want a bunch of 
images or words to appear in order --say, not more than two or three 
like stimuli in a row -- how do we manipulate the "random" sequence to 
avoid it?

If you get an answer to this question, I would like to know.
