+xHello everyone, I don't really know how to start my script, so I am asking for your advice. I would like to present 10 images to participants only once for 1000 ms, with an interval of 1000 ms between each image as well. I would like these images to be presented in a random order.
But the real sticking point for me is that I want one image out of the 10 to be randomly selected and presented 5 times instead of just once, but still randomly among the others.
This makes a total of 14 presentations, with one image being repeated 5 times.
Does anyone have an idea of where to start?
Thank you :)
