The first Cognitive Process that was in play according to the excerpt is Perceptual System. It is also called Perceptual Representation and Intelligence.
This function of the brain is responsible for the sensory input which may be auditory (sounds), visual (pictures), and kinesthetic (emotions or feelings).
So the Perceptual Cognitive system (visual) relays the input (image of the horse to his brain, then it is stored.
This next stage is handled by the memory. Memory (a crucial process for learning) is a cognitive function that enables us to code, store, and recover information from the past.
Notice that the man perceived the information, and as the input interacts with the memory, he is able to say that the image or picture contains a black horse because there is a recall function.
