In education, emphasis is often placed on content—what is taught, how it is taught, and how it is assessed. Yet neuroscience suggests an equally critical dimension: timing. When the brain is most receptive to learning may be as important as the material itself.
My research has explored how neural systems involved in reading develop over time, with particular attention to sensitive periods—windows during which the brain is especially responsive to specific types of input. These windows are not uniform across individuals, nor are they rigidly fixed. They are dynamic, influenced by both biology and experience.
Through longitudinal imaging studies, we have observed how the maturation of white matter pathways correlates with reading acquisition. In some learners, these pathways strengthen early, facilitating rapid progress. In others, development follows a different trajectory, requiring alternative instructional approaches.
For individuals with dyslexia, these differences in timing can be especially pronounced. Traditional educational systems, which often assume uniform developmental pacing, may inadvertently overlook or misinterpret these variations.
Understanding timing allows us to move toward more responsive models of education—models that align instruction with developmental readiness rather than imposing fixed schedules.
The recognition of this work underscores the importance of integrating temporal dynamics into our understanding of learning. It is not only about what the brain can do, but when it is ready to do it.
