• Hi @eduard, Thanks for your response! There was some variability (so not always 216 ms), so I ended up calculating the difference between the two timestamps and adding that to the RT. I did look into co-routines initially but since I had to run the…

  in Duration in sampler item and response time Comment by sflu September 2023
• Hi @eduard, Thanks for your response! In addition to response_time, I recorded the timestamps for time_sampler and time_keyboard_response, so if I subtract the keyboard timestamp from the sampler one, it right now comes out at about ~216. So it woul…

  in Duration in sampler item and response time Comment by sflu September 2023
• Hi, I think they solved the problem in this thread by putting a Python inline_script after the keyboard_response. I'm not sure if you have to set the duration of the sampler to 0 though, or leave it as "keypress". https://forum.cogsci.nl/…

  in music not stopped after keypress Comment by sflu September 2023
• Hi, Sorry, I meant in the data I downloaded after piloting the experiment. But I added an inline javascript item at the beginning of the experiment to record the JATOS worker ID, so it's all good now. Thanks!

• *Sorry, I meant to post this in the JATOS section as this is happened when I used my institution's JATOS server.

• That worked, thank you very much, @sebastiaan !

  in How to end experiment after certain number of incorrect trials Comment by sflu June 2023
• Hi @sebastiaan Thanks for your response! I haven't upgraded to 4.0 yet, so what I tried was putting [acc] > 67 in the Run if field of the parts of the experiment I want to run. This works in the sense that if you fall below 67 you are taken to …

  in How to end experiment after certain number of incorrect trials Comment by sflu June 2023
• Hi @Fab, Thanks, I will try out the Github method! I was also wondering about the Break if statement in the loop. Could I add something like Break if [response] = space so that they would then exit the loop upon pressing the space bar?

  in Audio file doesn't stop after keypress Comment by sflu May 2023
• Hi @Fab, Thanks, I got rid of the Python script and changed the Run if statement instead. I also unchecked the Reset feedback variables box for the per trial feedback items in the sequence. It seems to be logging accuracy and average rt correctly n…

  in Adapting coroutines for OSWeb Comment by sflu April 2023
• Hi @Fab, Thanks for your message! I haven't upgraded to version 4 yet, but it seems the accuracy and response time problem only started to happen after I added a timeout warning and a self-timed break (as in the screenshot). Before that everything …

  in Adapting coroutines for OSWeb Comment by sflu April 2023
• Hi! Thanks, I'll check out the latest version. I've actually gone into a different direction now, and just put a sketchpad telling participants that they've timed out (at 3000 ms) instead of playing an audio file. I've also added self-timed breaks a…

  in Adapting coroutines for OSWeb Comment by sflu April 2023
• Hi Sebastian, Thank you for your response! If I set the duration of the stimulus to 400 ms, the file will not finish playing if it's longer than 400 ms, though, right? We have a list of about 1000 nouns that participants will go through, and there i…
