[solved] Creating time stamps in eye tracking experiment
We are building a very simple experiment in opensesame (since this is the first time we are working with it), and we are using the Eye Link 2.
Basically, each trial looks like this:
(1) fixation (5sec)
(2) stimulus (i.e, a simple word) (5sec)
In total, we have three trials.
What we need to know is the following: We would like to send a message which is eventually printed in the final asc. file to see only the data about the eye behavior (i.e., pupil dilation, blinks, and fixation) only for the stimulus part (so not for the fixation part). Thus, we are only interested in the data for the eye behavior when the stimulus is presented.
For now, we only get the message when the trial starts and ends (but we cannot distinguish the fixation part from the stimulus part) (see also the example of our output).
Hope our question/problem is clear!
Thanks in advance.
