Startle probe or sound while showing image

[David McFarlane]

Jens,

Suppose your image object is called StimImage, and your startle sound 
object is called StartleSound.  Then try this:

Set Duration of StimImage to 5000 ms, and make sure that Clear After is No.

Set Duration of StartleSound to 5000 ms, and make sure that End Sound 
Action is (none).

Now StimImage will come on, and 5 sec later your startle sound will 
start, without erasing your StimImage.  Your startle sound will play, 
and the StartleSound object will continue to run the full 5 sec even 
after your sound file ends, completing the desired 10 sec interval.

If needed, you may also collect a response to either StimImage or 
StartleSound (or both, if you dare!).  If you want to collect a 
response to StimImage over the entire 10 sec, then set its Time Limit 
to 10000 ms (see Extended Input in Appendix C of the User's Guide 
that came with E-Prime).
