EARS AND EYES......................................

Auditory and visual processing: the  importance of the ears and the eyes

The eyes and the ears are the primary means of
delivering information to the brain, a process sometimes called “input.” If
either the eyes or the ears aren’t working properly, learning can suffer and
there is a greater likelihood of a learning disability or disorder.
Professionals may refer to the ability to hear well as
“auditory processing skills” or “receptive language.” The ability to hear
things correctly greatly impacts the ability to read, write and spell. An
inability to distinguish subtle differences in sound, or hearing sounds at the
wrong speed make it difficult to sound out words and understand the basic
concepts of reading and writing. 
Problems in visual perception include missing subtle
differences in shapes, reversing letters or numbers, skipping words, skipping
lines, misperceiving depth or distance, or having problems with eye–hand
coordination.  Professionals may refer to the work of the eyes as “visual
processing.” Visual perception can affect gross and fine motor skills, reading
comprehension, and math.
