[solved] repeat cycle until keypress

  Hi,

  You could consider setting the repeat value of your change_blindness_loop very high, and using a break-if statement to break out of the loop as soon as a response has been collected.

  For example, let's assume that you have an image_sequence that consists of presenting an image (defined by the variable image) and a keyboard_response with a certain timeout (say 100 ms). The following loop will then do the trick: image1.png and image2.png will be alternately presented until the keyboard_response doesn't time out.

  

  In addition, you will have to reset the response variable to None right before the loop. You can do this with an inline_script like this:

  # Reset the `response` variable to None
  exp.set('response', None)
  

  This may do the trick for you. Alternatively, if you need more flexibility, you could consider implementing everything with an inline_script.

  Cheers!

  Hi, we're back!

  Our experiment works! But now we have a problem with the logger (output).. We want to know how many cycles it took for the participant to see the change. We clicked 'correct' in the logger. First the output showed us a '0' or '1' for a correct response or not, only now it shows different values, such as '41', '0' or '23'. What does this mean? Is it a problem in excel or do we have to select different options in opensesame?

  Bye bye,
  Fenna

  We got a tip from a friend it may had something to do with multiple keyboard response objects.. We have four keyboard responses in our experiment :ar!

  Hi Fenna,

  Are you sure you're looking at the right column in the output? It kind of sounds like you're looking at the count_keyboard_response variable rather than the correct_keyboard_response.

  If this is not the case, could you post your script?

  Thanks!
