multiple procedures, nested lists, and complex stimuli

Dear E-Prime,
     I am posting this message for Alberto Pacios of University of La

Hi, everyone:

We're trying to make an experiment in which we present a series of  
complex stimuli, and then we ask a series of questions for each one  
of them. Then we continue with the next series of complex stimuli,  
and again we ask another series of questions. And again, and again…

Each "complex stimuli" is composed of a picture that stays visible  
while 2 phrases appear and disappear, one after the other. Also, each  
one of those "complex stimuli" has two particular questions  
associated to it (which we'll ask when we get through the end of that  
"series" of  complex stimuli).

Therefore,  I think it was necessary to give one row of the table to  
each "complex stimuli" (Pic - phrase 1 - phrase 2 - question 1 -  
question 2), so that the reference connection between the attributes  
wouldn't be lost.


In 2.6.6.2 of the User Guide, there is a way to delay the 'TEST' sub- 
procedure until after the 'PRESENTATION' sub-procedure has finished  
running the list of samples (without losing that connection): You  
make one supra-ordinated list object listing two sub-procedures in an  
attribute column, and you bracket-reference that attribute name as  
the procedure of the list of stimuli. You build the sub-procedures in  
the unreferenced E-objects briefcase, and voila, one sub-procedure  
runs the list of stimuli, and then the second sub-procedure runs its  
own way the same list of stimuli.


But I don't want it to run ALL the list of stimuli. Each cycle  
"presentation/test" must cover a SUB-group of the big list of  
-"complex"- stimuli.

I have tried a lot of ways to create nested lists to break the big  
list of stimuli into various sub-lists, yet I don't happen to find  
the exact combination of nested lists and the 2.6.6.2 trick.

Even so, I suppose this may be a common and probably basic need for  
most E-Prime users, and maybe you have a simple way to put me on  
track with this problem. I would very gladly receive any help..

Thank you a lot.
