Hello, 
I'm new to this group and also to e-prime software, so please excuse me if 
the question will sound simple to you...I tried to find a solution online 
without any results...
I'm creating my first experiment in e-prime and will be a continous 
performance test (CPT), a series of digits will be presented each one for 
200ms with a variable ISI between 800-2000 ms. Subject will have to press a 
button on a SRbox only to one specific digit (target ) while they don't 
have to press buttons to other digits. The problem is that the responses 
are not collected by EP after the duration of 200ms of the stimulus (I 
would like to allow a time limit of 800ms after the appearence of the 
target), I tried to extend timeLimit for the SRbox input but the response 
will not be recorded.
The experiment is divided in TrialList (list of digits presented in a 
random order), TrialProc with: Inline (to randomize the duration of 
fixation) / Fixation / Stimuli (with 200 of duration and timeLimit to 800 
but EP doesn't collect responses after the 200ms of the stimulus). Can you 
help me?
Thank you 
PM
