Poor Reading: A Deep Dive
The causes of poor reading
Understanding the mystery of poor reading skills
Poor reading skills arise from a combination of neurological, cognitive, and environmental factors.
There are many interwoven challenges, from genetic influences and brain processing differences to memory deficits and lack of early literacy exposure, these factors shape a child’s reading development.
How do they interact, and what can be done to support struggling readers? Read on to explore the key insights and solutions.
Reasons why a child might be a struggling reader
There is no single cause, but research has identified several major contributors:
Neurological and genetic factors
Developmental reading difficulties (dyslexia) often run in families, indicating a genetic basis. Brain imaging studies show that children with dyslexia exhibit differences in the brain’s reading network. For example, there are typically reduced activations in left-side brain regions (temporal and parietal lobes, and the fusiform “visual word form” area) during reading tasks. These brain differences mean that the neural circuits for processing print and language are not as efficient, making reading much more effortful for the child.
Cognitive factors
A well-established cause of poor reading is a deficit in phonological processing. This means the child has trouble analyzing and manipulating the sounds in spoken words, which impairs their ability to map sounds to letters when reading. Another common factor is slow rapid automatized naming (RAN) – struggling readers often cannot quickly name familiar symbols (letters, numbers) and this slowness reflects inefficiencies in the cognitive processing needed for fluent reading. Working memory also plays a role: if a child can’t hold sounds or words in mind, decoding and comprehension suffer. In fact, studies indicate that a weak phonological short-term memory (a component of working memory) can impair both word reading and spelling. Some research has pointed to visual-attentional weaknesses as well – for instance, difficulty focusing on all letters of a word (a reduced “visual attention span”) can limit how many letters the child processes at once. In summary, cognitive causes may include: poor awareness of speech sounds, slow processing speed, low memory capacity for print, and attention deficits. Each of these can contribute to the reading symptoms described above.
Environmental factors
A child’s literacy environment significantly influences reading development. Children who receive little exposure to reading – for example, not being read to at home, or lacking access to books – may start school behind in foundational skills. Socioeconomic factors often come into play: lower socioeconomic status is associated with fewer early literacy experiences and can delay reading acquisition. For instance, research shows that the home literacy environment (like how often parents read with the child) at ages 4–5 predicts reading outcomes in early elementary school. High-poverty schools sometimes have limited resources, and children in those settings are at higher risk for reading difficulties. Additionally, ineffective reading instruction can exacerbate problems. A child with mild decoding issues, if taught with inadequate phonics, might develop more severe reading failure. In short, limited practice, lack of quality instruction, or learning disruptions (such as chronic absenteeism or unaddressed hearing problems) are environmental causes that can compound a child’s reading challenges.
The intersection of poor reading causes
It’s important to note that these causes often interact. For example, a genetically at-risk child might cope well if given excellent early instruction – but struggle if they also have a poor home literacy environment. Understanding the diverse causes helps in planning effective interventions.

How Writing Problems Affect Reading
Trouble reading can sometimes start with how a child writes. In our next post, we explore how dysgraphia—a writing disorder—can interfere with reading fluency, comprehension, and confidence.
