Hello,
I am rather new to Inquisit as I am working on my first experiment. I wanted to use an AMP task and I have modified an AMP code that I found in the Inquisit library (AMP procedure found under
https://www.millisecond.com/download/library/amp). The main difference for my experiment is that I want to use a video as a prime instead of a picture. (I also have a second task where the video need to be rated on a Likert scale. This task runs without any issues.) It has been quite of a struggle to have the video running as it should, but we found a solution by adding a branch (see code below). Now I noticed that the target picture is present throughout the whole trial instead of being on screen for 100ms as coded in the parameters. It is visible behind the video and the mask. Could you please help me figure out how to fix this issue? I am completely stuck... Also, if you know of a better solution than adding a branch to have the video displayed as needed, I am more than happy to hear about it. You can find my code below. Note: I have two types of videos (called prime and shorts), they're the same, with one being cut to a shorter version (0.20 seconds for the AMP task, long version is 3 seconds long for the likert task). I omitted the text part of my code because they're not relevant to the issue here. Do let me know if I should add that too!
Thank you in advance for your help!
Warm regards,
Céline
