[open] Collecting multiple responses after succession of stimuli

  Hi Roelof,

  Would you mind elaborating a bit on what you mean with "referring back to past correct responses"? it is not entirely clear to me yet what you want to accomplish here.

  Generally, it is quite handy to use dictionaries if you want to keep things that belong together, stay together (e.g. questions with corresponding answers).

  Once you give a little more detail, I will also explain better how to do that.

  Thanks,

  Eduard

  Hi Eduard,

  I want to ask multiple questions in succession and then collect all the answers at once. In particular, subjects would get a number of sentences drawn from the block loop at random and after X sentences have to enter the last word of each those sentences at once.
  Does that make things clearer?

  Regards,

  Hi,

  And what would you measure? Only recall accuracy or anything else? And is X always the same number?
  It seems the easiest (conceptual) solution would be having a loop, in which you present all the sentences and that runs a certain number of iterations (either by setting it beforehand, or by breaking after a limit is exceeded). Once the loop is over, you could use a text_input_form to let participants type the words that they recall. Once you have the response, you can process it to find the corresponding response for each question.
  However, the implementation of that can be done in many ways. From what I get so far, it is hard to decide what would be the best. If you really need a clear advice, and some more guiding on how to structure your Opensesame code and such, you have to give us even more detail with respect to design, variables, etc.

  Does this help?

  Hi,

  The measure would be number of correct answers in the correct spot.
  That setup sounds like what I would like to have, but it's exactly that processing of the answers which I don't have working. I would like OpenSesame to automatically compare the answers in the text_input_form to the correct variable from the block_loop.

  If it'd help I could upload my experiment as it is now?

  Hi Roelof,

  Sorry for having let you wait that long. Sure, just upload the experiment, and I will have a look.

  Best,

  Eduard

  Hi Eduard,

  No problem, here is the link to the experiment: http://www.filedropper.com/ospan2
  I think the comparing of the answers can be handled afterwards with an excel script, so that's not a problem anymore. I have run into a different problem however. I want a few trials to be randomly drawn from a large pool of trials. In order to do this I have set the blocks to end at [count_trial_sequence] = 7. I've defined this variable to be 3 at the trial, and be randomized at the experiment, or at least I think that's what supposed to happen, but instead the variable behaves as if it is 0 the first time (and run 8 trials) and it doesn't get reset in the experiment. If you could help me with that that would be awesome!

  Regards,
  Roelof

  Hi Roelof,

  I am not super sure myself when It comes to use all the Opensesames count_XXX variables. When I want to do something similar, I usually create the variables myself.
  So in your case, you can say something like this:

  var.counter = 3
  

  in the prepare phase (not the run_phase) of that inline_script. And use the [counter]=7.

  Does this help?
