ABSTRACT
The kinds of behavior isolated in this chapter under the title of perception include the recognition of automobiles, airplanes, whistles, 25-cent pieces, pesos, or shillings, our homes and friends, and the odors, tastes, and feels of objects with which we have been in contact before. Since Aristotle, psychologists have acknowledged that in perceptual behavior objects mean something. For example, sounds are identified as the whistle of a steamboat or train, the putt-putt of a motorboat, the sounds of horses hooves, and so on.
