You need to add a <text> element to your script that contains the message(s). You need to "link" its items to the corresponding image stimuli as detailed in the "How to present stimulus pairs" topic in the documentation (or some variation thereof). Finally, you need to have the proper <trial> element in the script display the text stimulus.

You cannot display the message for 5ms only. That would require your display to operate at a refresh rate of 200Hz -- it is *very* unlikely that your monitor is able to do that. Typical refresh rates are in the range of 50Hz to 100Hz, i.e., a single display frame (and hence the minimum display duration for a given stimulus) lasts between 20ms and 10ms.

In general, I would recommend working through the tutorials included in the documentation prior to moving on -- that should give you insight into the basics of Inquisit syntax. Prior to modifying the AAT, then, make sure to first work through the original (unmodified) script and pay particular attention to the comments. Those will give you an idea what the respective part of the code does and how to modify it.

Hello,

I've downloaded the AAT script and edited it to use my image stimuli rather than the preprogrammed ones. However, for one of my experimental conditions, I would like to have a message flash briefly (~5 milliseconds) on the screen before the appearance of certain images. Is there any way to do this? I have very limited knowledge of coding or how this would be done as this is my first attempt at creating my own experiment. I can post the script that I have so far if that would be helpful.

Thank you!
