Adding image before each stimuli is presented

Hi guys, 

I am modifying the Penn Emotion Recognition Task (ER-40), which presents images of faces and then has the subject choose what emotion they saw. I would like to simply add another image before each face is shown, but I am struggling on how to do this. Where in the code can I add the image?

    values.target = list.itemnumbers.nextindex;

You'll want to replace /stimulusframes in <trial emotionRecognition> with /stimulustimes and define whatever timing and sequence of stimuli you want there.

Basics like this you will find covered in the tutorials in the Inquisit documentation. https://www.millisecond.com/support/docs/v6/html/tutorials/covert_attention/cacreatingtrials.htm

Thank you very much! I have been able to make that work well.

Additionally, I would like to present an image a single time before the /stimulustimes begins. How do I stop it from being presented after the first time?

Set up a trial that does notthing but display that image, run it a single time.
