response window

[PetCPR]

Hi, I have an experiment where I present a participant with 3 rapid
serial visual presentation streams of words. The task is to make an
animacy judgement on a target word in red in the central stream. The
central stream is flanked by 2 other streams where congruent/
incongruent words may appear at the same time, thus it takes the
participant about 1000 to 3000ms to execute the response. each stream
changes every 600ms, and so by the time the subject has made the
response, about 3/6 trials have already passed and the response made
is logged with one of the subsequent trials and not with target trial
where the target word appeared, likewise, the RT corresponds to the
time from the subsequent 3rd/6th trial to the time the response was
made, and not from the onset of the target word.

Is there anyway to program eprime to open up a response window on a
target trial of around 6000ms so that any response made during that
window will correspond to the target trial.

(I've overcome this problem in a way by changing the definition of
trial, so that it contains 6 slides instead of one, which does work,
but it makes programming very arduous, so if anyone knows a better way
that would be great!)

Thanks!
