This memory depends on associations

This memory depends on associations formed in the auditory realm alone, and therefore lacks the many aids to memory which are found in other types of learning. "If a child is shown a clock, he sees it, feels its shape, hears it tick, feels the coldness of it, etc. The different senses help him to realize the object, so that he can always recognize it as a clock in the future .... Absolute color consciousness seems to be more common than absolute tone consciousness. Very fine differences of color are recognized, and color shades are produced in imagination by the name. However, I find that the color always attaches itself to some definite object. I cannot imagine brownish red purely as a color, but must think of the portiere in my room.
