“Horses learn by habit. They gradually discriminate – to scratch against the best tree, to roll on the best surface, to drink from the best water spot. Learning proceeds gradually as the horse learns the relevant dimensions of the problem. They sense any changes in conditions and surroundings.
They can learn gradually without depending on the hippocampus because they are not memorizing but slowly mastering the problem as we would a skill like hitting a ball with a bat.”
