I have an experiment where I am conducting a memory test. In the recognition phase, I show participants images and ask them to rate the images based on a scale of 1-6 based on how old or new they think the image is. 1-3 on the scale = old, and 4-6 = old. I need participants to get feedback (correct! or incorrect!) based on the number they press. Eg. if they press either 1,2 or 3 and the image is old, i want the feedback to be correct. If they press 4 and the image is new, then the feedback should read incorrect and vice versa if they image is new.
How can I accomplish this?
