Images provide the world with visual summaries. In his book Ways of Seeing (Penguin Books, 1972), art critic and theorist John Berger writes, “Seeing comes before words. The child looks and recognizes before it can speak”. Our brains react differently to images than language, leaving many behavioral psychologists to believe that without pictures, words have no meaning – or at least no chance of retention. Even some of the earliest Paleolithic cave drawings, dating back as far as 40,000 years, are theorized as being ways of communicating with others.
