How the Brain Learns to Read

The visual cortex is where the brain
‘sees’ things. It helps us see and identify objects, shapes, pictures, and people.
The auditory cortex is where the brain
‘hears’ things. It processes sounds.
The Wernicke’s area is where the brain
understands what things ‘mean’. It maps the words we hear to their meaning and helps us
to process sentences. Before we learn to read, the Wernicke’s area helps us bring
meaning to spoken language. This is why talking to your children is important. Oral
literacy comes before written literacy.
Before we learn to read, the parts of the brain related to connecting letters to sounds
are disconnected.

The visual cortex can see the letter f but
it cannot hear the sound ‘f’ until a connection with the auditory cortex is formed.
Neural networks are the connections formed
between the visual and the auditory cortex connecting letters to sounds. The more we train
connecting letters to sounds, the more neurons we build, and the stronger these neural
networks become. So get going with our phonics practice!
The auditory cortex can hear the letter f
but it cannot see the letter f until a connection with the
visual cortex is formed.
The Letterbox does not exist in the brain of
a newborn child. It is an area of the visual cortex that develops only when we develop
neural networks that identify letters and map them onto their sounds. After lots of
practice mapping letters to sounds, this information is stored in this area, making the
process of reading gradually automatic.
The Wernicke’s area starts to change as the
brain masters reading. It learns how to map written language, not just oral language, to
meaning. Thus, we read the word ‘funny’ and map it to its meaning. We can also interpret
sentences such as ‘Bogart’s bulging bug eyes are funny!’.
The process of learning to read through phonics is about connecting different parts of the
brain.
A bra|n that |s learn|ng to read v|a the whole-word method, rather than through phon|cs
The visual cortex, the part of the brain
that helps us see things, can still be employed to see and identify whole words.
The auditory cortex, the part of the brain
that processes sounds, can still be used to connect whole words to their corresponding
sound.
However, the neural networks which connect
letters to sound are underdeveloped. As a result, children won’t be equipped to read words
they haven’t seen before.
When a child learns how to read via the whole-word method, reading engages parts of the
right hemisphere of the brain and the activity of the left hemisphere associated with
fluent reading is missing. Thus,
the letterbox, the part of the brain that
develops when we build connections between letters and sounds and lives in the left
hemisphere, doesn’t develop.
Wernicke’s area: This area that maps words
and sentences to their meaning is still used to interpret whole words.
