The
Reading
Brain
Reading is not a single process, nor is it the same across languages or learners. This domain explores how the brain learns to read, how languages shape that learning, and how instruction can support every reader.
The Reading Brain domain examines the science of reading from a cognitive, linguistic, neurodevelopmental, and instructional perspective. Our work challenges simplified assumptions about how reading develops and proposes a layered understanding that accounts for universal neural architecture, language characteristics, learner variability, and educational design. This body of research informs LAJAM's frameworks, curricula, and professional learning.
OVERVIEW
RESEARCH SYNTHESIS
There Is No Single Reading Brain: Toward a Layered Model of Reading Across Languages and Neurodevelopment
A synthesis proposing that reading is best understood as the interaction of universal neural architecture, language, learner variability, and instructional design.
RESEARCH BRIEFS
There Is No Single Reading Brain
Why reading is a dynamic system shaped by biology, language, and experience.
Fluent ≠ Academically Proficient
Why oral language proficiency should not be mistaken for academic literacy.
Reading Is Not a Visual Skill Alone
Understanding reading as a distributed process involving multiple cognitive systems.
Why Reading Science Cannot Be Language Neutral
The risks of applying findings from one language to another without adaptation.
Reading Changes Across Languages
How orthographic depth and linguistic structure shape the reading brain.
Supporting the Neurodiverse Reader
Research insights for dyslexia, ADHD, and other neurodevelopmental profiles.
VISUAL FRAMEWORKS
Layered Reading Brain Framework
A model illustrating the interaction of biological, linguistic, cognitive, and instructional layers.
The Cognitive Architecture of Reading
Mapping the systems involved in skilled reading development.
Reading Across Languages Model
Visual representation of orthographic adaptation across writing systems.
Reading Development Continuum
From emergent literacy to advanced comprehension: a developmental pathway.
