[solved] repeat sketchpad until correct response given

absurd · April 2015

Hi,

I am trying to build an experiment with this structure:

1 - Loop with the variables [stimulus] and [correct_response]

2 - Sequence

3 - Sketchpad ([stimulus])

4 - Keyboard_response (a;l as possible keys)

Now, I want another Sketchpad to appear only if the response was wrong:

5 - Sketchpad ('wrong!')

This works, if I set a run if statement for 5 in the surrounding sequence ([response]!=[correct_response]).

But now I want the Sketchpad 5 to be shown until the correct response is given.

How do I do that? I already started with nested loops and break if and also tried to do everything with an inline script but with no success so far. I think I need a while loop that collects a second keyboard_response.

Thanks for your help,

Johannes

Hi Johannes,

What happens, if you put following script in an inline_script after Sketchpad 5 (whose duration is set to keypress)?

from openexp.keyboard import keyboard
keyb = keyboard(exp)

while True:
    resp,time = keyb.get_key()
    if resp == exp.correct_response:
        break

I haven't tried it, but I believe this (or something similar) should do the trick.

Thank you Eduard,

That did the trick. I inserted this inline script (I had to change exp.correct_response to exp.get('correct_response'), though).

Then I set both Sketchpad 5 and the inline script to run if [response]!=[correct_response] within the surrounding sequence.

I still have to check if all the variables are logged that I want to be logged, but it already runs the way I want it to.
