Memory Training

Hello there! I’m no that familiar with PsychoPy, but I’d like to make a memory training program with it. Therefore, I’d need to have about 10 images on the screen at the same time and the participants would have to select some of the images by clicking on them. In the testing phase, the participants should remember their chosen images.
So Psychopy should recognize, if the images in the testing phase are the correct chosen ones from the training phase.

Could anyone please tell me how I’m supposed to make this memory training with PsychoPy?
Thanks and kind regards!
