N-Back Task problem
I have been encountering some problems while I try to use OpenSesame to develop a N-Back Task
Here's the link to my script file: https://drive.google.com/file/d/1wFmetLhfQaqYBf4gZWKmIALddNgqO000/view?usp=sharing
This is my first time using software like OpenSesame. I was trying to develop a 2-back task which participants have to judge and respond to item that matches the one that presented 2 items ago. I used 8 letters (B, F, K, H, M, Q, R, X) as stimuli, and I wanted each letter to appear 6 times within a list, once as a target. Before the experimental trials begin, there will be 10 trials of training with feedback. Afterwards, participants will perform four blocks 48 trials without feedback.
However, when I performed a quick run of my experiment, I found it cannot give feedback properly. I used two sketchpads, one with a red cross and one with a green circle to represent incorrect and correct responses. Sometimes the feedback came before the keyboard response and sometimes when I gave the correct response it gave me an incorrect response feedback.
I have defined those two sketchpads to run if [correct] = 0 and [correct] = 1 but it was still not working.
Moreover, I have no idea how to enter the target letter with the full-factorial design button as my experiment wasn't a factorial experiment. Therefore, I entered the stimuli manually:
It was okay for me to enter the trials manually for the practice block as there was 10 trials only. However, it would be quite time consuming if I have to manually enter all four experimental blocks of 48 trials. So I would like to know is there any way that is more convenient to develop a block loop for my 2-back task? I have tried to search for Python codes for N-Back Task but I have no idea how to use them.
