Logging response times after stimulus presentation

[David McFarlane]

Christina,

I would try the following:

Make a Slide with both the image and the sound.  Set Duration to 
"(infinite)", and End Sound Action on the SlideSound sub-object to 
"Terminate".  This will run the Slide until the end of the sound.  Do 
not use an input mask here.

Follow this with a Wait object to collect the response, using 
appropriate Duration, input mask etc.  Your image will remain on the 
display while the Wait object runs & collects the response.  (I think 
of Wait objects as "null" stimuli and use them primarily when I want 
to get a response without presenting a stimulus.)

That should do it.
