Hello, I'm COMPLETELY new and I've been struggling to create conditioning. I have 4 neutral images, 2 positive and 2 negative pictures. I need every neutral picture to draw one positive or negative picture and remain in this pair till the end of conditioning. It is essentiall that each time (in case of different particiapnts) every neutral photo schould randomly choose positive or negative image. I've managed to create drawing but my stimuli pairs are changing, they do not stay together until the end. I would be very gratefull for any help...
dog, dolphins are negative
biketrip, doggys are positive
