New Brain Research Supports Early Intervention

“Our findings suggest that some of these kids walk into their first day of kindergarten with their little backpacks and a less-optimal brain for learning to read, and that these differences in brain development start showing up in toddlerhood” (Mineo, 2026). Brain development begins at conception according to its genetic code, which is influenced by its environment. Each set of genetic coding is unique, except for identical births. Some individuals have the genetic coding to develop brain pathways that are different than most individuals, like dyslexia. This makes learning how to effectively process symbols/letters, words, and their meanings more challenging. Environmental factors will influence the severity of dyslexia and learning how to read.

“The brain bases for reading-related skills are being built in infancy, long before children learn to read” (Mineo, 2025). Researchers have identified three regions in the brain that work together to process written symbols. The first region is the anterior. This region located in the front left side of the brain and is responsible for processing phonological information. The second region of the brain that helps to effectively process printed information is the temporoparietal region. This region is in the mid-left side of the brain and processes orthographical information into patterns of speech and meaning. The third region that helps to effectively process written information into sound and meaning is the occipitotemporal region, located in the back, lower left-side of the brain. This region stores a picture of each word along with its sound and meaning. These regions work as a team to read written words. https://www.zaner-bloser.com/research/building-the-reading-brain

Students with developmental dyslexia do not develop the infrastructure within their brain to initial process written letters or symbols. Their brain processes written information through different routes than most  individuals. They use the anterior region in the left side of the brain and parts of the right brain to process written words. The connections between the temporoparietal region and the occipitotemporal region are not yet developed. Students with dyslexia compensate by using parts of their right brain, until the necessary connections of the left-hand side of the brain are developed. Their brain works twice as hard to process the information. This is why many students with dyslexia do not show outwards signs of a disability until they start trying to make sense of or use written words. These students usually become tired, frustrated, and check-out. This often leads to the “lazy” look. These individuals usually need direct, explicit instruction to help develop the necessary connections in the left side of the brain.

There are also many environmental factors that may have an influence on the developing brain. One factor is the community of people in the developing brain’s immediate environment and what their habits may entail-nurturing, chemicals. Another factor is technology, the amount of use or interaction with different types of technology will affect the developing brain, such as a pencil or mechanical or electronic devices. The amount of television and programs viewed will affect the developing brain. Another factor is the amount and types of conversations the developing brain hears. Another factor is the amount of print the developing brain is exposed to. Another factor is the amount of interaction the developing brain is given through different senses-sight, sound, taste, touch, and smell.  The environmental factors that the developing brain is exposed to helps to develop the layers of information or knowledge that individual’s use when learning to read and reading information in print. If the process is slowed, stopped, or altered by environmental factors, the results will be altered. Often when students struggle in learning how to read, we do not know all the factors involved that have developed the student disability.

Many of the initial layers of knowledge necessary to read written words are not seen or heard while growing, like the first initial growth of a plant. A plant seed uses its “genetic” coding to begin growing. Like a human seed, the plant seed needs the right environment to begin growth. A plant first grows roots. Then a stem begins to grow. Then leaves begin growing. This growth all takes place usually unseen, underground. The plant has been developing the connections necessary to survive out of the soil. Once the plant has poked out of the soil it will continue to grow according to its genetic design, affected by environmental factors. Like the unseen plant growth, the human brain develops in layers. Many layers are unseen, like before individuals begin to talk. The brain or person observes and listens for quite some time (about a year) before spoken utterances begin. The fruit of their observation is realized gradually overtime. The number of spoken words grows overtime, along with the complexity of verbal sentence structure.

Current research suggests that the brain begins categorizing and storing new information at conception. The foundational layers necessary for future affluent reading becomes more prevalent around age 18 months. The complexity of the brain is developed enough to determine who will struggle with phonological processing. At this stage of development researchers were able to determine “individual differences in early brain structure associated with phonological processing and mediate decoding and word reading ability in early school” (Mineo, 2025). The lack of phonological processing skills is a major indication of dyslexia or deficiency in learning how to read written language.

These new findings support prior researchers’ conclusions. Fowler (1983) theorized that a person’s environment has influence on their genetic code and that individuals develop in a layered manner. Piaget (1966) theorized that as a child’s body maturates, the more complex their brain can process information. Vygotsky (1934) theorized individuals first process information orally, until the age of 7 when they begin processing (thinking) information both internally and externally. He also theorized that individuals layer their knowledge through the help of their community environment. Meaning students usually cannot complete an activity before the foundation for that activity is developed without the assistance of another individual who has the prior knowledge or foundational skills of task. Binet and Simon (1906) theorized that children will be able to complete certain tasks at a particular age, but usually not before. For instance, Binet and Simon (1916) discovered that a picture could determine a children’s intellectual age at three, seven, and twelve. Three-year-old children give simple explanations of the people within a picture, but not the background or happenings of the people within the picture. Children at the intellectual age of seven can examine a picture and describe the relationship of the people and objects within the picture. At the intellectual age of twelve, children can give an interpretation of the picture. The interpretation is expressed in written form about their feelings in relation to a description of the picture.

Intervention usually assists in the development of connections (by-ways and high-ways) within the brain. This usually leads to effective reading skills when practiced and practiced and practiced. These students will need extra time to grow and practice each newly acquire skill with in the complex system of affluent reading.

Cognitive Brain Development Theories

Current research confirms earlier brain development theorist that suggested brain development takes place in a structured systematic fashion. For years researchers have suggested that individual’s cognitive processing skills develop in a layered manner. Now we have fresh research conducted with new forms of technology not available to most of these researchers to validate their theories. Four relevant cognitive development theories concluded before current technology are described below.

The first theory was developed by Binet and Simon in 1916. Their work established the intelligence guidelines that we use today. Educators at the time were struggling to accurately label struggling students or why students did not all respond to same types of curricula at different levels of education. Binet and Simon’s research determined how the brain functioned at different age levels. The results of their research show that a student gains cognitive processing skills or cognitive intelligence in a systematic manner. For example, they discovered that a picture could determine a child’s intellectual age of three, seven, and twelve. Three-year-old children give simple explanations of the people within a picture, but not the background or happenings of the people within the picture. Binet and Simon noted, “At three years, therefore, the child is at the stage recognition and identification of objects” (p. 190). The answers are usually given in simple one-word sentences. Children at the intellectual age of seven can examine a picture and describe the relationship of the people and objects within the picture. Binet and Simon noted that the answer is given in complete sentences. At the intellectual age of twelve, children are able to give an interpretation of the picture. These interpretations are expressed in a written description of their feelings that are attached to the description of the picture. Children begin to view the whole picture and the meaning of the picture as they grow intellectually.

The second theory was developed by Vygotsky through his research from 1926 to 1930 that focused on “the mechanism of transformation of natural psychological functions into the higher functions of logical memory, elective attention, decision making, and comprehension of language” (Vygotsky, 1934, p. xxvii). Vygotsky’s research in educational psychology led to cognitive rehabilitation practices. He focused on the mental age and the functioning age of children and discovered that ages were not always the same. Vygotsky also discovered that children maturate in a stratified, blended pattern. Vygotsky’s cognitive development theory rests on the amount and type of social interaction that takes place during the maturation process. Vygotsky (1934) argued that children will exhibit higher cognitive functions in an enriched environment. Cognitive functions of children will increase as they master social processes. Vygotsky’s research led to two major findings of cognitive development, the zone of proximal development and inner speech.

The third theory was realized by Piaget (1966), who worked for Binet in the mid-1920s. His findings were not made known until the mid-1960s. Piaget argued that when children’s bodies go through the maturation process, their brains also move into higher levels of cognitive processing. Piaget (1966) concluded that “mental growth is inseparable from physical growth: the maturation of the nervous and endocrine systems, in particular continues until the age of sixteen” (p. xvii). Piaget considered cognitive development within the womb to be more genetically linked than environmentally linked. For Piaget the environment takes on a larger role of development of cognitive intelligence outside of the womb. Piaget (1966) argued that individuals develop their cognitive processing skills at different ages, each level building on the previous level. Piaget established four major levels of cognitive development: sensori-motor, semiotic or symbolic, concrete operations, and propositional operations or pre-adolescent.

The fourth theory was formed through Fowler’s (1983) research that focused on the effects of stimulation on cognitive processing development. A portion of his research focused on language development and the cognitive process of learning how to read. Fowler (1983) theorized that cognitive development was founded on two major explanations that involved the environment and genetics. According to Fowler (1962), the inherited design unfolds itself through “ordered stages of maturation” and is modified through the child’s environmental experiences (p. 143). Fowler argued that the cognitive processing skills of children will grow through the acquisition of layered skills and that children must be able to question before they can reason. Fowler argued that cognitive development is dependent on three main skills as well as motivation. He suggested that these skills were knowledge, codes, and problem-solving strategies and styles. Formal knowledge is how the information is processed, used, and stored within the brain. Codes refers to the use of codes, which are the connections within the brain that allow children to catalog, store, and retrieve vast amounts of information. The complexity of the code connections grows as children maturate. Strategies represent the style of processing information. All children demonstrate different tempos for processing information. All children have different forms of analyzing and integrating information into brains. Fowler (1983) recognized Piaget’s basic stages of cognitive development, but he felt that cognitive development occurred in a blurred rather than a rigid formation. He felt that all new cognitive processing skills are developed based on previously developed cognitive skills.

Current research that supports the theories explained above will be described in my next blog.

Composing Written Words

Writing is an exercise that requires higher cognitive processing abilities. These skills take time to develop, as children need to first build the foundations or connections necessary to speak words and sentences. This skill begins to appear around age two when children are beginning to build their own oral sentences. Some children will begin earlier; some children will begin later. Student brain connections begin developing under the direction of their genetics gained at conception. They are listening and observing others to learn how different sounds convey meaning. The brain continues to build roads, highways, and by-ways according to their genetics and their environment. They will build the necessary connections to survive in their immediate environment under the direction of their genetics. This means making the connections to coordinate information between the necessary parts of the brain for speaking and writing language. This means developing connections to synthesize stored and new information. A child’s immediate environment will either increase or hinder their oral language growth. A child’s oral language ability usually dictates their reading and writing ability. There will be exceptions, like students with dyslexia.

Brain development occurs in a systematic or ordered fashion, like a flower growing from a seed. The flower grows systematically in stages. We can observe some stages of the flower’s development, while other stages are invisible or internal. Some flowers take longer to mature; other flowers are slower to mature. Writing skills are developed in a similar fashion. There are five stages that students move through while learning how to write (Voyager Sopris Learning, 2025). The first stage is pre-phonemic – scribbling/drawing, usually not legible. The second stage is early phonemic – begins to recognize and emulate letter shapes. The third stage is strings of random letters – able to write letters, writing nonsense words. The fourth stage invented/transitional spelling – encoding words, putting phonemes together based on the sounds of a word. The fifth stage is conventional writing and spelling – able to write coherent sentences and passages, often relying on their phonics knowledge. The growth is both seen and unseen.

Often student brain connections or routes have not developed enough for them to transfer their oral language to paper. Vygotsky (1934/2002) theorized that children first process and compose their verbal language aloud through others in their environment. At this stage of development individuals in the student’s environment are more likely to hear unfiltered verbiage, like he stinks or their shirt is dirty. At this stage their brain is relying on just one route of thought called interpsychological. Around ages 7-9 the student brain will begin using a second thought processing route that Vygotsky (1934/2002) referred to as intrapsychological or inner speech. Students compose their own thoughts without filtering them through their environment. They begin to individualize their thoughts relying more heavily own data bank of information instead of those in their environment. Students begin refraining from sharing their exact thoughts.

In the formal classroom, students are often shut down or not allowed to talk while independent writing is taking place. Most students in the primary grades need to express themselves orally before putting words on paper. Their brains have not moved from one processing route or verbally thinking to having two routes to process their thinking. Creating a writing environment that gives opportunity for a variety of different volume levels allows students to orally express and discuss composing their writing, and it gives an opportunity to focus on putting their oral composition onto to paper.

A student who seems to be lazy or unengaged is typically struggling to write words on paper. These students are still gaining the foundational writing skills in stages 1-3. They are building the necessary connections to write words on paper. These students are usually frustrated and feel degraded. They begin to navigate ways around the task.

If a student is struggling to verbally express a coherent sentence, then direct, explicit instruction in a small group needs to take place. You become their co-author. You become their sounding board. You become their scribe. The student should write the scribed sentence in their own handwriting. This helps students to build their handwriting connections to put words on paper. Small group instruction allows the instructor to work with students more at their zone of proximal development. When students are ready for this instruction with the assistance of someone of higher cognitive processing. They will likely be stuck for some time without your assistance. This is also a form of scaffolding.

Appropriate Reading Rate

What is the appropriate rate when reading a passage? The short answer is that an appropriate rate for reading is the rate in which a person might speak when having a conversation. This may be slightly different for each individual based on their processing abilities. Many mechanisms or tools must work together for an individual to read at a conversation rate. Research suggests what the “normal” rate of reading should be for students at each grade. For example, in August/September a Grade 2 student who reads 111 words per minute is in the 90 percentile for reading rate (Hasbrouck & Tindal, 2017). A Grade 2 student who accurately reads 84 words per minute during the Fall screening is at the 75 percentile of reading rate. Reading words too fast or too slow compromises the comprehension of the words read (White, 2024; Hasbrouck, 2024). Students who are reading too fast do not allow their brain to fully process the meaning of the word, sentences, or passage. Students who are reading too slow are usually focusing more on how to accurately pronounce the words. When a student reads words at a good rate, they are more able to think deeper about the passages that they read. This increases their comprehension ability, as students usually synthesis while they read to make smarter conclusions and choices.

The rate of reading involves several mechanisms working together to provide the intended outcome. Why do we read? We usually read to communicate and learn, which involves understanding the words read. The mechanisms are located in different parts of the brain to process written language. One mechanism is phoneme awareness, which is the ability to recognize and manipulate sounds of a spoken word. A second is phonics knowledge. This is the rules of phonemes and graphemes that give students the power to decode words. A third tool is orthographic awareness. The rules of how letters are ordered to create written words of meaning. A fourth mechanism is morphological knowledge. The smaller parts of words that form the meaning of words. A fifth tool is semantics. The meaning of a word, sentence or passage read. A sixth mechanism is syntax. The rules of how a sentence should be formed – grammar. When one of the above mechanisms is lacking age-appropriate ability (under developed) the rate of reading will be affected. An under developed tool usually means intervention instruction to increase student ability. Students begin to automatically divide and conquer multisyllabic words based on their knowledge of phonemes, graphemes, syllables, and morphemes. Student deficits will be different based on their educational and environmental experiences, and their genetic make-up.

There are a couple more tools that have important roles in student reading rate. Student retrieval rate (cognitive processing ability) of known words from long-term memory. This may be affected by multiple factors, such as how information is categorized in the brain. This will be unique for each student based on their genetics and environmental experiences. Another tool that may cause havoc on student reading rate is their working memory (short-term). The amount of information that each student is able to hold in their working memory.

Reading fluency involves student ability to read the words at the rate and prosody of conversation without error. These are not naturally acquired skills. These are learned skills that require the brain to create connections between different brain tools.

Orthographic mapping is “the process of storing a word permanently in memory for instant retrieval” (Reading Rockets, 2024).
