ABSTRACT
Human learning differs fundamentally from the learning of other animals in its extensive use of concepts. Concepts are formed through the experience one has of reality, and one of the most important elements in concept formation is the process of perception. Until one perceives an object as a thing in itself it is impossible to develop a concept of a class of such things. Similarly, unless we single out the important features of an object or action it is difficult to generalize from our experience. In order to illustrate this process let us first examine what happens when we perceive the world around us.
