Affective Stop Signal Task
I am doing experiments for my thesis and I am quite stuck ! I am trying hard to understand and do it well but even after read 653 posts on forum and seen 76 video about opensesame and python (thank you so much for all of these really helpfull material!) I am still struggling.
So, I am doing an Affective Stop Signal Task; affective because we have pictures with faces (fear or neutral) and participant have to respond if the person on the picture is a women or a man.
But my problems are :
- Jittered fixation dot : 1200 - 1500 : I have been trying with the advanced_delay but before every Stop signal, the fixation dot stay longer than in target.
- I tried the adaptive procedure that prolongs the stop_signal delay SSD (seen on the forum, +50ms if success, -50ms if unsuccess) but not sure it works.
- I have some trouble to adapt the size of the images, like it is really bigger than the frame, so how to do that ?
- I wrote every tries, one by one so there are 320 tries (!!) I am sure there is a solution to have less lines. My variables : GO; Stop_signal // fear, neutral // images (with 120 go fear, 120 go neutral, 40 stop fear, 40 stop neutral) // correct_response : f;h.
Hopefully it makes sense.
Thank you again for all your tutorial!
