Randomize pair of stimuli between subject but maintain same pair within subject
Hi everyone, I've read something similar in another discussion but I was wondering if anyone coul help me because they're some things I don't understand. I'll try to explain my experiment as well as I could, English is not my first language.
I have an associative learning task in which participants should learn the value of several stimuli. I have 20 stimuli (10 images of cheese and 10 images of wash machines) and I want them to be presented with a random value picture (high or low value). I have three columns, one for stimuli, one for correct value and another for incorrect value. I want to randomize which value pairs with which picture between participants (same number of hight and low values) but they have to see the same pair in every block (the pair will be shown untill they get a minimun accuracy). So I want pairs images to be randomize between participants but maintain same pairs within subject.
Thank you so much for your help :)
