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.
