Re: [APD] Scale representation

How about a ruler *and* a coin? Coins are psychologically more 
identifiable. It allows the unconscious mind to process the scale 
without needing to engage in abstract thought. Most people do not carry 
rulers around, and so they do not know how everyday objects measure up, 
so to speak. People do, however, encounter coins almost every day of 
their lives. That makes them intimately familiar with how their size 
relates to other things in their environment. You can glance at a 
picture with a coin in it and know how the subject will appear if it was 
in your hand. With a ruler you have to stop and think about it (and 
probably have to get a ruler out).
