Group: Forum Members Posts: 32, Visits: 41	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

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. Attachments ENCODE Forwards.iqx (139 views, 89.00 KB)

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>.
