 It is important here to distinguish perceptual learning from learning that is simply based on perception (see Dretske 2015: fn.  6).[3]  Perceptual learning involves changes in perception, while learning that is based on perception need not. Looking at my table, I might learn that the cup is on the table. However, this does not involve any long-term changes in perception. It is learning that is based on perception, but it is not perceptual learning. Furthermore, I might learn to put the cup on the table into the dishwasher every time it is empty. Again, this is learning that is based on perception (I need to perceive the cup in order to move it). However, it is not perceptual learning.
