The Dyslexia Duo: Mark Seidenberg on Language, Reading Science, and Teaching Kids to Break the Code

The Dyslexia Duo hosts Melissa Dean and Aimee Rodenroth interview cognitive scientist and neuroscientist Mark Seidenberg, author of Language at the Speed of Sight, about connecting reading research to classroom practice. Seidenberg explains he wrote the book to share foundational science and to critique the gap between research and how reading is taught, which he ties to limited teacher preparation and schools of education being historically isolated from psychology and linguistics. They discuss the central role of oral language—especially encouraging children’s speech production—and how wide variation in spoken language affects reading success, with technology and reduced reading to children contributing to vocabulary gaps. Seidenberg frames reading as “unnatural” at the start, requiring explicit instruction to “break the code,” then increasingly relying on implicit/statistical learning, and argues for efficient early instruction, similarity-based approaches for irregular “sight” words, and developmental resolution of the reading wars.
