I am trying to create an experiment where images are shown from a potential bank.
There are 8 images (4 pairs of images, but they come in 2 different conditions). In each block, the participant needs to see one condition/form of the image pairs. This happens for 4 blocks.
How would I go about randomising the order of the 4 pairs of images, and which condition the participant gets for each block?
Please could someone help with this?
