The Cognitive Science of the Reading Brain

While reading might feel natural for skilled readers, beneath the surface, the brain is doing something remarkably complex. Understanding how we learn to read can help us design better instruction, provide richer support for new readers, and keep children motivated to persevere through challenges. Rally Reader explores what cognitive science reveals about the reading brain, what reading does for language, and why encouragement and instruction matter more than ever.

How We Learn to Read

The process of learning to read involves the brain rewiring itself. Unlike spoken language, which most children naturally acquire through listening, reading is not innate. The brain must repurpose multiple areas to map visual symbols (letters) onto sounds and meanings.

These neurological pathways become stronger as a child practices reading. When supported with effective instruction, the neural connections in our brains are shaped in ways that support fluent, automatic reading (Lexia).

What Reading Does for Language

Developing reading skills also strengthens language comprehension. This means that weaknesses in either decoding or comprehension will limit a reader’s ability to fluently and effectively read. Even if a child is a strong decoder, poor language comprehension can prevent them from fully grasping what they read (NWEA).

Decoding written language is not a simple task. It requires the coordination of visual, auditory, and cognitive processes (for example, recognizing letters, mapping them to sounds, blending those sounds effectively, and understanding the text). Comprehension depends on a child’s oral language skills: knowing what words mean, understanding sentence structure, having relevant background knowledge, and being able to make inferences in text. While there is no “correct” speed to blend sounds for effective reading, fluency is achieved when a reader can proficiently recognize (or sound out) enough words to comprehend what they read, rather than focusing on the mechanics of reading. A standard benchmark for fourth grade reading speed is between 90 and 140 words per minute, with comprehension ((National Center on Improving Literacy and The Nation's Report Card). 

Why Instruction, Motivation, and Encouragement Matter

Because reading does not come naturally, quality instruction must be explicit, systematic, and cumulative. The science of reading, which includes the body of research that brings together neuroscience, cognitive psychology, and education, shows that children can learn to read well if they are taught in ways aligned with how their brains are developing. Holistic literacy education occurs when young readers receive the instruction and encouragement that helps them build the intrinsic motivation to read (Lexia).

Through structured, supportive instruction, children build accurate decoding skills while nurturing the language comprehension they need to make sense of what they read. Motivation and encouragement drive practice, which in turn builds the very neural connections that make reading easier over time. At Rally Reader, we support literacy development on every front: we offer gentle correction, build motivation through meaningful practice and appealing titles, and help develop language skills in a nurturing, evidence-based way.
