ABSTRACT
Sight is universally regarded as the most highly developed of all human senses. Hence it is not surprising to find that the question, “How do we see?,” has been faced, and variously answered, since earliest times. Psychologists have a special interest in the question, because the visual input plays such a dominant role in our experience and behavior. Such expressions as “seeing eye to eye” with a person, “seeing the point” of a joke or an argument, and discovering that someone is not very “bright” attest to the fact that the language of vision often enters into our everyday speech and thinking.
