Aristotelian Theories of Perception in the Middle Ages

Some medieval authors explicitly say that human beings perceive in a different way just because we are also rational beings. But there are some medieval authors who also think that at least some of the sensory processes are exactly the same in non-human animals and in us. So you mean we can see and a dog can see, but something different might be happening when we see them when a dog sees? Yes, that's a possible way of thinking. And one of the biggest differences to Aristotelian theories that some authors defended was the idea that the mind is somehow active in perception.
