Using stimuli based on participant answers

First, my generic answer to the recurring question of, "Can E-Prime 
do this?"  In short, almost certainly Yes; in full, E-Prime is a 
fairly full-featured computer programming platform, and can in 
principle do anything that a Universal Turing Machine (e.g., a 
stored-program computer) can do, subject to performance limitations 
(e.g., speed and storage capacity).  In practice, E-Prime  provides a 
better representation for some tasks than for others, as is true of 
any representational system for anything (grammar, images, time 
series, music, etc.).

Second, for what you want to do, you should look first at the 
"Study-Recall" example that you may download from PST.  Good luck!

Stock reminder:  1) I do not work for PST.  2) PST's trained staff 
take any and all questions at 
http://support.pstnet.com/e%2Dprime/support/login.asp , and they 
strive to respond to all requests in 24-48 hours -- this is pretty 
much their substitute for proper documentation, so make full use of 
it.  3) In addition, PST takes questions at their Facebook page 
(http://www.facebook.com/pages/Psychology-Software-Tools-Inc/241802160683 
), and offers several instructional videos there and on their YouTube 
channel (http://www.youtube.com/user/PSTNET ) (no Twitter feed yet, 
though).  4) If you do get an answer from PST staff, please extend 
the courtesy of posting their reply back here for the sake of others.
