Multiple correct responses

edited October 2017 in OpenSesame

Hi

Is it possible to use multiple values as correct responses for each cycle? I am building an experiment with touch screen but I could not find a way to do that.

Thanks.

  • Hi,

    You'll want to take a look at this discussion:

    There's much bigger issues in the world, I know. But I first have to take care of the world I know.

  • Thank you Sebastiaan for your reply.
    In my case I need to collect the touch screen response rather than keyboard response right ? but I alrealy do not have any experience with that, could you tell please how to get this data?

    Thanks

  • Hi,

    The touch_response item does quite a few things, so re-implementing it completely in an inline_script is inconvenient. However, what you can do is change the correct value of the last-recorded response. The following script, which should be in the Run phase of an inline_script that immediately follows the touch_response, does that. (Note: This is a hack that directly accesses the internals of OpenSesame. But it does work.)

    # Define a list of correct responses
    correct_responses = 2, 3
    # And then alter the correct value of the last response. This is a hack!
    last_response = responses._responses[0]
    last_response.correct = last_response.response in correct_responses
    

    You can also define your correct responses in the loop table, in which case you would do something like:

    # Define a list of correct responses based on the loop table
    correct_responses = var.correct_response_1, var.correct_response_2
    

    Cheers!

  • Thank you for your reply. I tried your suggested solutions but it is not working with my experiment, I checked the log file many variables such as correct, correct_new_touch_response and correct_response are "undefined". Do you know why?
    I am using OpenSesame 3.1.9 in Windows 10

    Thanks

  • Hi,

    Could you upload your experiment? Then I'll have a quick look at can check what is going on there.

    Thanks,

  • Thanks eduard for your reply. I have attached my experiment.

  • Hi,

    To get a working var.correctvariable. You have to change the line:

    correct_response = 2,3 to correct_response = [2,3]

    and add the line var.correct = last_response.correct at the end of the inline_script.

    Hope this helps,

    Eduard

  • Many thanks eduard, it is working fine now.

    I have a small issue, I could not find user's responses for each cycle. It was recorded under correct_new_touch_response column but now it shows "undefined" value. Do you know how can I fix that?

    Thanks

  • Hi,

    Does the variable response have the information yo need? I bet the data is somewhere, just look through your file and see whether you can find it.

  • Thanks eduard.
