“A lone man stands stock-still before an armored tank, daring it to move forward, small yet large in his defiance. That picture, a frozen moment from the student uprising in Tiananmen Square, resides indelibly in the minds of all who gazed upon the portrait of singular courage. But now try to remember the headline that accompanied the photograph displayed above the fold in the morning paper. Try to recall the caption below that defined the image, the body copy running in column inches beside and beyond that detailed the drama. Odds are all those hundreds of words, painstakingly selected, words that loaded the picture with meaning, put it into cultural context, have faded from thought, while the image remains. But fret not the forgetting; it is simply a part of the human condition. Because, as visually oriented systems, humans are programmed to store more pictures than text in their long-term memories.”
