Three problems after importing the study

Comments

  Hi Cody,

  Let's see.

  When I finished the coding successfully, which means the experiment runs perfectly on my computer,

  Can you tell me a bit more what you mean exactly? Do you have a local JATOS running on your computer, and the results get correctly stored on the JATOS database? From your message, I think the answer is yes to both these questions, but want to double-check.

  The consent page shows twice. This situation only happens after I import the jzipped file to the public server. 

  This is weird. If you try it on the sever (is this MindProbe?) can you also reproduce this error? If so, do you see any errors in the console (your browser's developer tools) when clicking the first time?

  the status always show"DATA_RETRIEVED"

  If the data are immensely big, it's possible that participants closed the experiment tab before sending the data. Unlikely, but possible I guess. And this would not happen on a local JATOS when there is no remote server to send the data to. So, again to check, a few questions: (1) do you get the results stored properly on your local JATOS? (2) How big is your dataset? (3) can you reproduce this behaviour? ie when you click on the general multiple link and complete the study, what happens with your results?

  Hi Elisa,

  Thank you for replying to me!! Maybe I explain not clearly through words. Do you mind if we can have a zoom meeting with each other? If not, I will try my best to explain everything in words. Thank you!!

  Dear Elisa,

  Yes. I have a local JATOS running on your computer, but I don't whether the results get correctly stored on the JATOS database or not. I add code based on https://www.jatos.org/jsPsych-and-JATOS.html instruction. I have screen-cut my coding for your information. Please see the attached photos. Thank you!

  This is weird. If you try it on the sever (is this MindProbe?) can you also reproduce this error? If so, do you see any errors in the console (your browser's developer tools) when clicking the first time?

  This problem only shows on the general multiple links that I send to my participants.

  If the data are immensely big, it's possible that participants closed the experiment tab before sending the data. Unlikely, but possible I guess. And this would not happen on a local JATOS when there is no remote server to send the data to. So, again to check, a few questions: (1) do you get the results stored properly on your local JATOS?

  Do you suggest there is something wrong with my coding? I can not receive any result when I or the participant finish the study through the general multiple links.

  Again, really appreciated your kind reply. Please feel free to ask me questions :)

  Regards,

  Hi cody, can you send me the General Multiple link? I'd like to check it in my browser. If you want, this is my address: lange.kristian at gmail.com.

  Hi cody,

  I looked at your code. It mostly looks fine but you do a turn short before you are about to finish.

  You have a final trial that redirects to Prolific. Here are the important parts of your code:

  var jsPsych = initJsPsych({
     on_finish: () => jatos.endStudy(jsPsych.data.get().json())
  });
  
  ...
  
  // Thank you page
  var final_trial = {
      type: jsPsychHtmlKeyboardResponse,
      stimulus: `<p>You've finished the last task. Thanks for participating!</p>
  <p><a href="https://app.prolific.co/submissions/complete?cc=xxxxxx">Click here to return to Prolific and complete the study</a>.</p>`,
      choices: "NO_KEYS"
  }
  timeline.push(final_trial);
  
  jatos.onLoad(() => {
      jatos.addAbortButton();
      jsPsych.run(timeline);
  });
  

  You redirect to Prolific in the last trial and jsPsych on_finish callback is never called and therefore the study never finished and result data never transferred.

  Remove the final trial and let JATOS do the redirect to Prolific for you: https://www.jatos.org/Use-Prolific.html. Just put the Prolific URL in your study's study properties / End redirect URL (in JATOS).

  Best,

  Kristian
