[solved] Is it possible to repeat the previous trial when the subject took the incorrect response?

edited January 2014 in OpenSesame

Hi, Sebastiaan.
Sorry, if there are similar comments.

I want to "correction" trials after incorrect responses by the subject. A "correction" trial is a repetition of the previous trial condition until the subject responded appropriately. And also, I use loop and random order of trial conditions. When I use loop and random order, is it possible to repeat the previous trial condition? How can I do this?

Thank you for your consideration.

    Hi Koba,

    This is a common question, and a feature request has been filed (link). It's not easy to do right now, but with a little clever scripting it can be done.

    Basically, what you need to do is maintain a list of conditions that need to be repeated. At the end of the experiment, you walk through this list, thus running 'correction' trials.

    Here's a simple example that shows how to do this. You'll have to adjust it to fit your paradigm, obviously, but it conveys the general idea:

    Hope this helps!

    Regards,
    Sebastiaan
