How does experience affect visual perception? Provide an example in your response.

In his work, Theaetetus, Plato wrote,
"Perception, then, is always of what is, and unerring."  However, Socrates contended
that "perception is unerring--as befits knowledge."  Of course, science has proven that
the eyes do not actually see anything.  They are simply organs of vision:  When light
hits the lenses of the eyes, nerves are excited and then carry messages to the brain. 
The brain then comprehends the messages of the nerves and the person "sees" the
object(s) viewed. Since, each person's brain differs in its knowledge, then
understanding of the messages from the nerves will necessarily
differ.

A very simple example of this interpretation of
visual perception can be witnessed as a student from a lower socio-economic class reads
aloud.  Since he/she has learned substandard English at home and in his/her environment,
this student may read "he has seen" as "he seen" even though the Standard English is in
print.
