In a LinkedIn comment, David Chalk said: "Our brains have been wired hundreds of thousands of years to speak and interpret by hearing words, but there is no natural ability to read-attaching sounds to symbols-words."
This is making statements without thinking. He repeats what he has read from others such as Stanislas Dehaene and Pamela Snow. Dehaene does not answer questions asked, and Pamela Snow thinks she becomes invisible when she sticks her head in the sand. She blocked me when she could not answer the questions, I asked her. It is irresponsible to say something on social media and to not respond when relevant questions are asked.
The noted neuroscientist Stanislas Dehaene (2018) argues that there is no place or mechanism in the brain to accommodate the learning-to-read process, seemingly adding credence to the reading-is-unnatural assumption. Dehaene and other researchers point out that oral language has been around for 50,000 years, whereas written systems developed much later—as recently as 5,000 years ago.
