Specifying onset of response time

[David McFarlane]

Debra,

Hmm, wouldn't that be nice.  But as far as I know E-Prime cannot do 
this, though perhaps someone else has a better answer.  I would just 
measure RT from the start of the audio, then during data analysis 
subtract out the known time from the start of the audio to the onset 
of the verb.  Or, if you really need that data at run time, include 
the verb onset times in your stimulus list, and then add a bit of 
inline script to do any needed calculations.
