Sending Keyboard responses to OnsetSignalPort

[David McFarlane]

Semeon,

That would be nice wouldn't it?  But I do not see any way to use the 
stimulus OffsetSignal to output a response measure.  OffsetSignal 
values are set statically before the stimulus object runs, so it does 
not have any mechanism for outputting a value determined dynamically 
during the stimulus.

But for other ideas on this, see the threads at 
https://groups.google.com/d/topic/e-prime/z8PQMH1cf70 , 
https://groups.google.com/d/topic/e-prime/7w5ajYuHqgw , and 
https://groups.google.com/d/topic/e-prime/OeiZ00V9SRc .  A few more comments:

- These threads boil down to using WritePort at the time of response.
- Alternatively, you could follow the stimulus with inline code to 
set the OnsetSignalData of the next object, and let the next object 
(e.g., a Wait object with Duration 0) output the signal.
- With Task Events, you could skip all the inline code and use an 
object after your stimulus to output the response measure (see, e.g., 
https://groups.google.com/d/topic/e-prime/fAHqIoYiW1A ).

Hope that helps,
