Intriguing Fact

I've been reading some really difficult academic papers for a class I'm taking. The topic is how the brain works when people read--what exactly is occurring. It is incredibly dense and difficult to read. I have to really concentrate, and sometimes read it aloud to myself to absorb any of it. It is fascinating what some of the researchers have done with timers that can tick off milliseconds, for instance.

But here is the intriguing fact: when person learns numerals or the alphabet, it is the first time that the orientation of an object counts toward the identity of the object. The lower case letters b,d,q, p & g can be written in an identical form EXCEPT for the orientation...get it? (Also 6 & 9)So, for the first time, something every baby learns---Mom is Mom even if she is upside down, (and therefore all other tangible objects have this quality)---for the first time, this is no longer true.

It's amazing that anyone can learn to read at all.
