[visionlist] RTs and Windows

[Elliott, Mark]

 Dear netters and listers, 
 
it's an old issue but what is the current state of the art as regards recording reaction times under MS Windows? My last attempt, using Psych toolbox running under Windows XP, with a special wrapper in the code to prioritize the appropriate interrupt, recorded up to 36 ms error relative to the timing of a concurrent EEG trigger. What might the error be without these precautions, for example in a Dos box running directly from Windows?
 
Would you record RTs in Windows?
 
all the best
 
Mark
