Emig breaks down language into two major “orders”. First, talk/listen – both natural elements of language that requires no formal instruction. Second, read/write – both found in systematically learned instruction. He continues to define brain functions (left and right hemisphere) but attests to the fact that “writing involves the fullest possible function of the brain that requires full participation of both left and right hemisphere."
He suggests to the reader that writing is: a slower method of learning, but a powerful learning strategy that uses a higher cognitive function of analysis and synthesis.
