Hi all,
I wanted ask and see if anyone knows how to send an event marker after each stimuli is presented from an Inquisit script to Acqknowledge?
Our experiment has participants watch 1 minute videos and have them describe what they just saw, and we would like to collect physiological data in conjunction with the video viewing and response. The issue we are having is figuring out a way for Inquisit to send an event marker into Acqknowledge after each stimuli is presented and ends, so that we can accurately see the timepoints where a video started and ended, and when the response section started and ended.
In a nutshell, what type of code would I need to use in order for Inquisit to send an event marker to Acqknowledge after each stimuli is presented?
Any help would be appreciated!!

Here is our code for our experiment (without putting ports in). We have 6-7 videos in "FormA"
