"Error Message" for N-back Task

charsiubhau — Wed, 16 Nov 2022 18:12:20 GMT

Hi Dave,

For the 2 key N-back task a "correct" or "incorrect" message pops up during practice trials if there is an incorrect or no response.

I was wondering whether it would be possible to remove the "incorrect" message when the task first begins and there is no correct/incorrect response available yet (e.g., first 2 numbers for the 3-back task not showing "incorrect" because 3 stimuli haven't appeared yet). Let me know if you need more info!

Sincerely,
Belle

The 2-key N-back task as it exists in the library ( https://library.millisecond.com/v6/nback/singlenbacktask_shapes_2keys/singlenbacktask_shapes_2keys/singlenbacktask_shapes_2keys.iqzip/singlenbacktask_shapes_2keys.iqzip ) does not provide response feedback during practice, so I'm confused what exactly you're referring to.

Hi Dave,

I think you coded it so that it does provide response feedback during the practice trials. I'll attach the script below for reference.

I didn't code it this way, you had already added feedback to the practice block in the script you provided ( in this thread https://forums.millisecond.com/Topic34790.aspx ). I left it as-is.

Anyway, if you want to exempt the "start" trials from the response feedback, add /errormessage = false and/or /correctmessage = false to <trial start>.

Thank you so much! This worked :)
