If your child struggles with spelling, you’re not imagining it—and you’re not alone. Research is increasingly revealing that specific processing differences in the brain can create very real challenges with writing and spelling. A groundbreaking study published in Frontiers in Neurology is now showing exactly how visual field differences can affect spelling performance, offering new hope for understanding and addressing these challenges.
Research Discovery Links Vision and Spelling
A new peer-reviewed study published in March 2026 has identified a significant connection between specific visual field deficits and spelling performance in adults with Posterior Cortical Atrophy (PCA). This research, appearing in Frontiers in Neurology, reveals that visual processing differences can directly impact the ability to spell accurately.
The study found that homonymous hemianopia—a condition affecting visual field perception—was associated with declining spelling skills. This mechanistic understanding is groundbreaking because it shows that what appears as a “spelling problem” may actually stem from visual processing differences in the brain.
New research confirms what we've always believed: spelling difficulties stem from developable skills, not fixed limitations. Your child's brain can change. Here's what this means for your family.
Why This Matters for Young Learners
While this research studied adults with PCA, the findings have profound implications for understanding children’s spelling and writing development. The brain’s visual processing systems play a critical role in how we perceive letters, words, and spatial relationships on a page. When these systems don’t develop in typical ways, children can struggle with tasks that others find straightforward.
Importantly, this research reinforces something Learning Success has long emphasized: difficulties with spelling and writing often have identifiable neurological roots that can be addressed through targeted intervention. The brain’s visual processing skills can be developed through specific training, just like any other skill. Learn more about visual processing development.

From Symptoms to Solutions
Understanding the mechanism behind spelling difficulties transforms how we approach them. Rather than simply accommodations or coping strategies, we can now target the specific visual processing skills that support spelling success. This is the difference between managing symptoms and building actual skills.
The research shows that visual field deficits don’t just affect what we see—they impact how the brain processes written language. By strengthening these underlying visual processing skills, children can develop improved spelling abilities. This aligns with neuroplasticity research showing that the brain changes through targeted practice.
At Learning Success, we address visual processing through our Brain Bloom system, which targets the specific visual skills that support reading and writing. Explore our visual processing approach.
Key takeaways
- Research Discovery: New study shows visual field deficits directly impact spelling performance.
- Mechanism Understanding: Visual processing differences create real spelling challenges that can be addressed through targeted training.
- Hope for Parents: Brain research confirms skills can be developed—your child can build stronger spelling abilities.
The Path Forward
This research represents a growing body of evidence that spelling difficulties stem from developable skills, not fixed limitations. As we better understand the neurological mechanisms, we can create more effective interventions that target root causes rather than symptoms.
For parents, this means hope. Your child’s brain is capable of change. The visual processing skills needed for spelling can be developed through appropriate training. The key is identifying which specific skills need strengthening—and then targeting those skills directly.

Every child can develop new skills. Your child’s brain is not broken—it’s developing, and it can change. Research continues to confirm what we’ve always believed at Learning Success: when we identify the specific processing skills that need strengthening and target them with appropriate training, children build real capabilities.
The system that would have you believe these challenges are permanent limitations is wrong. Your expectations, your involvement, and your belief in your child’s potential are the most powerful forces for change. That’s not just optimism—it’s neuroscience.
If you’re ready to stop guessing and start building your child’s actual skills, the Learning Success All Access Program offers a free trial that includes a personalized Action Plan—and you keep that plan even if you decide it’s not the right fit.

Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
