[solved] Countdown display

edited June 2013 in OpenSesame

Hi,

I need to create a 30 second countdown display for an experiment I'm designing. It will occur automatically after an instruction screen and session 'X' of the experiment will follow the countdown. Essentially it will act as a distractor so that instructions are not maintained in participants WM.

Unfortunately I am new to OpenSesame, programming in general (let alone Python). Please assume complete naivety with regards to programming!

Any help would be great - this probably will not be my last SOS...

Thanks!

    Please ignore - figured it out with a feedback loop!

    wait! how did you do it?

    Create a feedback loop with variable 'countdown' (or whatever!). Insert the numbers 1 thru 30 into 'countdown'. Create a sketchpad item within the fb loop and insert your variable using the square brackets method (I.e. ['countdown']). That should do it!

  • Count you or somebody explain this in more detail? Thanks!!!

  • Hi Viennese,

    Basically, you need to create a sketchpad for every second that you want to present. So, if you want to have a 3 seconds countdown, you need to have three sketchpads, each having a duration of 1 second. In the first one you write something along the lines of "The next block starts in 3 seconds", for the second sketchpad, something like "The next block starts in 2 seconds" and so forth. If you feel like it, you can also implement this via a loop (if you have a countdown of 30 seconds, it is a little tedious to create 30 sketchpads).
    Does that clear things up?

  • Hi,
    I have a similar problem I'm currently struggling with. I want to display a countdown to the user as soon as he comes to the sketchpad slide. In thirty seconds I want to have a look on matrizes presented on the slide.
    How can I make the countdown visible to the user?

    Thanks in advance

  • Hi,

    You can wrap a loop around the sketchpad slide, that includes the counter of how many second are left (in addition to your actual stimulus). Make the sketchpad be presented for a little under 1 second and you should be good. Attached a small example how this could look like.

  • Hi Eduard,

    could you re-upload the file? I can't seem to access it.

    Thank you!

  • Hi Charlotte,
    Unfortunately I can't (I don't have backups of former uploads). Also, I assume that this is the same question as in this discussion: https://forum.cogsci.nl/discussion/372/solved-navigating-back-and-forward-in-an-exeperiment-some-more-questions#latest
    So, I'll answer there instead. If this here is in fact a different issue, let me know.
