The Dyslexic Brain and Reading: Why Reading Can Require More Effort
In the first post of our Dyslexia Awareness Month series, “What Does Dyslexia Actually Affect? Understanding Reading, Writing, Spelling, and Language,” we explored an important idea: dyslexia is about much more than simply “having trouble reading.” Dyslexia can affect several interconnected components of literacy, including phonological processing, decoding, spelling, reading fluency, and written expression. Understanding those individual components helps explain something that can be confusing for parents: Why can reading remain so difficult for a child who is intelligent, motivated, and clearly understands the material?
A child with dyslexia may be curious, hardworking, and knowledgeable. They may have an impressive vocabulary, excellent verbal reasoning skills, and a strong understanding of complex ideas. They may genuinely want to read. They may spend hours practicing. And yet, reading can still feel exhausting. This is not a contradiction. Reading is a complex skill that requires the brain to coordinate multiple processes quickly and efficiently. For individuals with dyslexia, some of the processes involved in learning to read—particularly phonological processing and decoding—may remain less automatic. As a result, reading can require more conscious attention and mental effort.
Understanding why this happens can help parents move away from the misconception that reading difficulty reflects a lack of effort. Instead, it allows us to recognize that the amount of effort a child puts into reading and the ease with which reading occurs are two different things.
Learning to Read Is Not Automatic
One of the first things to understand about reading is that the human brain is not naturally wired to read in the same way that it is naturally prepared to develop spoken language. Children typically acquire spoken language through exposure and interaction. They do not need formal instruction to understand that sounds combine to form words or that words can be used to communicate ideas.
Reading is different. The brain must learn to connect a visual system—the written symbols on a page—with the language system that represents sounds, words, and meaning. This process requires instruction and practice. When children are learning to read, they must develop an understanding of the relationship between letters and sounds. They learn that particular letters or groups of letters represent particular speech sounds. They then learn to blend those sounds together to identify words. For example: /m/ + /ă/ + /p/ → map
At first, this process may require considerable conscious attention. With experience, the goal is for word recognition to become increasingly automatic. A proficient reader generally does not need to consciously think through every letter and sound in a familiar word. The word is recognized quickly, allowing attention to shift toward comprehension. For a person with dyslexia, developing this automaticity can be more difficult.
What Does “Automatic” Reading Mean?
Imagine that you are driving a familiar route. You may arrive at your destination without consciously remembering every turn you made. You know the route so well that much of the process has become automatic. Now imagine driving through an unfamiliar city while simultaneously trying to follow complicated directions. You can still get where you need to go, but the task requires much more conscious attention. Reading can work in a similar way. For a skilled reader, recognizing familiar words is often highly automatic. This frees cognitive resources for understanding the meaning of the text, making connections, evaluating information, and thinking critically.
For a reader with dyslexia, word recognition and decoding may remain more effortful. The reader may need to devote more attention to figuring out individual words. When that happens, fewer cognitive resources may be available for everything else. This helps explain why a child can be highly intelligent and still struggle with reading.
The Role of Phonological Processing
As discussed in the first post, phonological processing plays an important role in reading development. Phonological processing involves the brain's ability to recognize and work with the sound structure of language. One particularly important component is phonological awareness—the ability to identify and manipulate individual sounds within spoken words. For example, a child may need to recognize that the word “fish” contains three sounds: /f/ /ĭ/ /sh/. They then need to connect those sounds to written letters. This may seem simple to an experienced reader, but it represents a complicated set of processes for a beginning reader. For many children, these connections become increasingly efficient through instruction and practice. For children with dyslexia, the development of these sound-based representations and connections may be less efficient. That does not mean the child cannot learn them. It means the pathway to efficient reading may be more difficult.
Decoding Is a Major Piece of the Puzzle
Decoding is the process of translating written symbols into spoken language.
When a child encounters an unfamiliar word, they may use knowledge of letter-sound relationships to work out what the word says. A child with dyslexia may have difficulty making this process efficient and consistent. For example, when encountering an unfamiliar word, the child may:
Pause frequently
Sound out individual letters or syllables
Lose track of the sounds
Guess based on the first letter
Substitute a familiar word
Need to reread the word
Have difficulty combining sounds smoothly
Struggle more as words become longer or more complex
These difficulties can persist even after substantial practice. A parent might reasonably wonder: “But we've practiced this word so many times. Why is it still hard?” The answer is that practice does not always produce the same level of automaticity for every learner. A child may know how to perform a skill without that skill becoming effortless.
Knowing How to Read Is Different From Reading Automatically
This distinction is extremely important. A student may eventually be able to decode a word correctly but still require substantial effort to do so. Imagine two students encountering the word “transportation.” One student recognizes it almost immediately. The other student works through: “trans...por...ta...tion.”
Both students may ultimately read the word correctly. But the cognitive demands are different. The second student has spent significantly more attention and time on the word. Now imagine that this happens dozens or hundreds of times while reading a chapter. The difference becomes much larger.
This is one reason reading can be exhausting for students with dyslexia even when they have learned many of the underlying skills.
Why Effort Matters
Reading requires attention. When decoding is automatic, relatively little conscious attention is needed for familiar words. This allows the reader to devote more attention to comprehension. When decoding remains effortful, attention is continually pulled toward word recognition. That can affect:
Reading speed
Reading stamina
Comprehension
Working memory
Recall of details
Ability to make inferences
Ability to monitor understanding
This does not necessarily mean the child has a comprehension problem. Instead, the child may be experiencing a bottleneck in accessing the information. Think about listening to someone speak while there is significant background noise. You may understand what the person is saying, but you have to work much harder to process the message. Reading can create a similar experience for someone whose word recognition is not yet automatic.
Why Intelligent Children Can Still Struggle
One of the most damaging myths about dyslexia is that significant reading difficulty should not occur in an intelligent child. In reality, intellectual ability and reading efficiency are not the same thing. A child can have strong:
Verbal reasoning
Vocabulary
General knowledge
Problem-solving skills
Memory for meaningful information
Creativity
Curiosity
Spatial reasoning
Abstract thinking
and still experience significant difficulty with decoding and reading fluency. In fact, some highly capable children with dyslexia may be particularly confusing to adults because their oral abilities can mask their reading difficulties. A child may participate in sophisticated classroom discussions and understand concepts that are well above their independent reading level. They may know the answer when the teacher asks a question verbally but struggle when the answer must be found in a textbook. They may explain a complex topic beautifully but avoid writing about it. This discrepancy can sometimes lead adults to conclude that the child is not trying. Often, the opposite is true.
Motivation Does Not Eliminate a Learning Difference
Another common misconception is that children will read better if they are sufficiently motivated. Motivation matters for learning, but motivation cannot eliminate the underlying cognitive demands associated with dyslexia. Consider a child who wants desperately to read a particular book. They may be highly interested in the story. They may genuinely want to know what happens next. They may be willing to practice. But if decoding remains effortful, reading that book may still require significantly more energy than it does for a fluent reader.
Motivation can encourage a child to persist. It cannot make an inefficient process instantly automatic. This distinction matters because children with dyslexia often hear messages such as:
“You just need to try harder.”
“You're not paying attention.”
“You know these words.”
“You're capable of doing this.”
While these statements may be intended to encourage a child, they can unintentionally communicate that their difficulty is a choice. A more accurate message is: “I know you're working hard. Let's figure out what part of reading is taking so much effort.”
Reading Fluency Is About More Than Speed
Parents sometimes hear the term “fluency” and assume it simply means reading faster. Fluency involves more than speed. It includes:
Accuracy
Appropriate rate
Smoothness
Expression
Automatic word recognition
A student who reads slowly but accurately may have a different profile from a student who reads quickly but makes many errors. Likewise, a student may eventually become highly accurate but continue to read much more slowly than peers. That slower rate can matter academically. As children move through school, they encounter increasingly large amounts of text. A student who needs twice as long to read a chapter may have significantly less time and energy available for other assignments. By middle and high school, this can become particularly challenging. Students may be expected to read:
Textbooks
Articles
Primary sources
Novels
Directions
Online materials
Test questions
Written instructions
Supplemental readings
The academic problem may therefore shift from “Can this student read?” to “Can this student efficiently access the amount of reading required?”
Why Reading May Become More Difficult as School Gets Harder
Some children appear to improve substantially in elementary school and then struggle again later. This does not necessarily mean their dyslexia has suddenly worsened. Instead, the demands of reading have changed. Early elementary reading may involve short, relatively simple texts. Later academic work requires students to read longer and more complex material, including words with multiple syllables, specialized vocabulary, and increasingly complicated sentence structures. Students are also expected to learn new information through reading independently. A child who has compensated successfully with strong memory, context clues, oral discussion, or intensive effort may reach a point where those strategies are no longer enough. This is why some students are not identified with dyslexia until middle school, high school, or even adulthood.
The Hidden Cost of Effort
One of the most important things parents can recognize is the hidden cost of reading effort. A child may complete the assignment. They may get the correct answers. They may appear successful. But how much energy did it take? A child who spends 30 minutes reading a passage that takes another student 10 minutes may have less energy available for homework afterward.
They may become irritable.
They may avoid reading.
They may complain of being tired.
They may procrastinate.
They may need frequent breaks.
They may appear inattentive.
These behaviors can sometimes be interpreted as motivation or attention problems when they are actually responses to cognitive fatigue. This does not mean that every child who avoids reading has dyslexia, or that attention difficulties cannot coexist with dyslexia. In fact, learning differences can overlap. It simply means that the effort required to complete an academic task is important information.
Accommodations Can Reduce the Burden Without Lowering Expectations
Supporting a student with dyslexia does not mean making schoolwork easier or lowering academic expectations. Instead, accommodations can reduce unnecessary barriers so that students can demonstrate what they know. Depending on the student's needs, supports may include:
Text-to-speech
Audiobooks
Extended time
Reduced copying demands
Access to digital text
Opportunities to demonstrate knowledge verbally
Explicit instruction in reading skills
Structured literacy instruction
Reduced emphasis on spelling when spelling is not the skill being assessed
Alternative ways to access lengthy reading assignments
The goal is not to prevent the student from learning to read. Rather, the goal is to provide both appropriate reading instruction and access to information while those skills are developing. A student should not have to choose between learning grade-level science content and struggling through every word in a science textbook independently.
Effective Reading Instruction Still Matters
Accommodations are important, but they are not a replacement for effective reading instruction. Students with dyslexia benefit from instruction that directly addresses the skills underlying reading difficulty. This may include systematic and explicit instruction in areas such as:
Phonological awareness
Sound-symbol relationships
Decoding
Encoding and spelling
Syllable patterns
Word structure
Morphology
Reading fluency
Instruction should be matched to the student's specific profile and delivered in a way that provides sufficient practice and feedback. The goal is to help the student develop increasingly efficient pathways for reading rather than simply encouraging them to compensate indefinitely.
A Strengths-Based Way to Talk About Reading Difficulty
The way adults talk about dyslexia matters.
Instead of saying: “Why are you still struggling with this?”
Try: “Your brain is working really hard to figure out these words.”
Instead of: “You know this word.”
Try: “Let's give your brain another way to access this word.”
Instead of: “You need to read more.”
Try: “Let's find ways to build your reading skills while also making sure you can access the information you need.”
And instead of: “You're smart enough to do this.”
Try: “I know you are capable of understanding this. Let's figure out what is making the reading part harder.”
These messages separate ability from access. That distinction can protect a child's confidence and help them develop an accurate understanding of their learning profile.
What Parents Should Take Away
If your child is intelligent, motivated, and knowledgeable but continues to struggle with reading, that difficulty deserves to be taken seriously. Persistent difficulty with decoding or reading fluency is not evidence that your child is lazy or isn't trying hard enough. As we discussed in the first post of this series, dyslexia can affect the underlying processes that support reading—including phonological processing, decoding, spelling, and fluency. When these processes remain effortful, reading can require significantly more cognitive energy.
Your child may know the information.
They may understand the story.
They may have the vocabulary.
They may have strong reasoning abilities.
They may desperately want to succeed.
And reading may still be hard.
That is not a contradiction.
It is one of the reasons understanding dyslexia matters.
Reading is a complex skill that requires the coordination of language, attention, memory, visual processing, and knowledge of written language. For most skilled readers, many aspects of word recognition become highly automatic. For individuals with dyslexia, decoding and related processes may remain less efficient and require more conscious attention. That extra effort can affect reading speed, stamina, comprehension, academic performance, and a student's willingness to engage with reading. Most importantly, effortful reading is not the same thing as a lack of intelligence or motivation. When parents understand the difference between knowing how to read a word and being able to recognize it automatically, many previously confusing behaviors begin to make sense. The goal is not to ask children with dyslexia to work harder at an inefficient process. The goal is to provide appropriate, explicit instruction that builds reading skills while also providing accommodations that allow students to access information and demonstrate their knowledge.
In the next post in this Dyslexia Awareness Month series, we'll build on this discussion by looking more closely at why direct, explicit phonics instruction is necessary for students with dyslexia.
