<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I see I might have been unclear in my original post- I apologize.
I am aware of being able to create a number of lists- and for each list counterbalance
stimuli manually i.e:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>List 1= 1a, 2b, 3c, 4a, 5b, 6c,<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>List 2= 1b, 2c, 3a, 4b, 5c, 6a<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>and then at the Block level have E-prime choose to present
one of these lists using the counterbalance display option. However, unless I
manufacture each possible list sequence this is really pseudorandom in that
anyone who sees stimulus 1a, will also see stimulus 4a and 5b etc. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Would someone be so kind as to tell me how I might list my
stimuli in a way that has E-prime *<b><span style='font-weight:bold'>randomly</span></b>*
select whether a Ss sees version ‘a’, ‘b’, ‘c’
of a given stimulus and across the whole experiment would see an equal number
of stimuli across the three conditions (a, b, c) where no stimulus (e.g.
stimulus 1) was seen in more than one version (e.g. 1a *<b><span
style='font-weight:bold'>or</span></b>* 1b *<b><span style='font-weight:bold'>or</span></b>*
1c). <o:p></o:p></span></font></p>
