About Mark
Mark Seidenberg is a cognitive scientist and psycholinguist whose work focuses on how people learn to read, how language is represented in the brain, and how research can better inform educational practice.
He is an emeritus professor at the University of Wisconsin–Madison, where he held the Vilas Research Professor and Donald O. Hebb Professor of Psychology appointments. Over the course of his career, his research has contributed to foundational theories of reading, language processing, and learning, including influential computational models of how written and spoken language are acquired and used.
His book, Language at the Speed of Sight, brought decades of research to a broader audience, examining the gap between scientific evidence and classroom practice in reading instruction. His work has been widely cited in discussions of literacy education and the “science of reading,” helping shape how educators, policymakers, and researchers think about reading development.
Background and Path
Seidenberg grew up on the south side of Chicago and attended local public schools before going on to the University of Chicago Laboratory School. That experience exposed him early to academic thinking and writing. Although he was not initially a standout student, he developed a strong interest in writing and analysis, including an early paper applying Aristotle’s Poetics to literature—an approach that foreshadowed his later work bridging theory and real-world application.
As an undergraduate at Columbia University, he was introduced to psycholinguistics, a field that studies how language is learned and processed. At the time, the field was heavily influenced by the ideas of Noam Chomsky, whose theories about the innate structure of language shaped much of the research landscape. Seidenberg continued on to earn a Ph.D. in psychology, focusing on experimental studies of word recognition and sentence processing.
Research and Contributions
Seidenberg’s work has centered on understanding how reading works at both cognitive and computational levels. In collaboration with colleagues including James McClelland, he helped develop a highly influential connectionist, or neural network, model of reading. Often referred to in cognitive science as the “triangle model,” this framework demonstrated how reading can emerge from interactions among orthography, phonology, and meaning—that is, spelling, sound, and meaning—without relying on rigid rule-based systems.
This work played a key role in shifting debates in cognitive science about how language is learned, contributing to broader discussions about learning, representation, and the role of experience in shaping knowledge.
At the University of Southern California and later at the University of Wisconsin–Madison, his research expanded to include models of reading difficulties, including dyslexia. These models explored how variations in processing capacity and learning conditions could lead to the patterns observed in struggling readers—ideas that continue to influence research today.
Reading, Education, and Public Impact
Beginning in the 2010s, Seidenberg increasingly focused on the disconnect between research on reading and how reading is taught in schools. This work culminated in Language at the Speed of Sight, which examined how misconceptions about reading development became embedded in educational practice.
His work has been part of a broader shift toward evidence-based literacy instruction, often referred to as the “science of reading.” While this movement has influenced policy and legislation across many states, Seidenberg has also emphasized the complexities of translating research into practice, noting that scientific findings can be oversimplified when turned into rigid rules or mandates.
Current Work
Seidenberg retired from his academic position in 2024. He continues to write and speak about reading, language, and education, with a focus on improving how research is interpreted and applied in classrooms.
His current work reflects a longstanding goal: to bring greater clarity to how reading works, how it is learned, and how scientific knowledge can be used more effectively to support both teachers and students.
A More Personal Note
Behind the academic work is a path shaped by writing, language, teaching, and the places and people that influenced him along the way. From growing up in Chicago to studying language and psychology in New York, from early work in psycholinguistics to decades of research on reading, Seidenberg’s career has followed a consistent thread: understanding how people learn, how language works, and why that knowledge matters outside the laboratory.
Throughout his career, his work has been shaped by an interest in connecting theory with real-world problems—whether in understanding how people recognize words, how children learn to read, or how educational practices evolve. That perspective continues to guide his writing and research today.
