Couldn't do picture matching and couldn't do the experiment under one loop
I am trying to do a visual memory task with same person's 7 different facial expressions
I want to show a -lets say- happy face picture first and then randomly showed 7 picture that includes happy face. I want participants to remember and detect the happy face.
I figure it out how can I do randomization
but I couldn't do matching phase and I couldn't do the experiment under one loop
I would be very grateful if someone tell me where is the problem
Here is my experiment's overview
