Explore the relevant research into the causal theories of dyslexia and explain the difficulties that learners with dyslexia may experience and the impact on learning.
One of the most prominent theories of dyslexia is the phonological deficit theory, which suggests that dyslexia is caused by difficulties in processing the sounds of language. Individuals with dyslexia may have trouble distinguishing between similar sounds or blending sounds together to form words, which can affect their ability to read and spell correctly.
Another theory is the visual magnocellular deficit theory, which suggests that dyslexia is caused by a problem with the visual system. Specifically, this theory suggests that individuals with dyslexia have difficulty processing rapid visual stimuli, which can affect t

Additionally, there is evidence to suggest that dyslexia may be caused by a combination of genetic and environmental factors. Some studies have identified specific genes that may be associated with dyslexia, while others have found that environmental factors such as prenatal exposure to alcohol or nicotine may increase the risk of developing dyslexia.
Learners with dyslexia may experience a range of difficulties when it comes to reading, writing, and spelling. These may include difficulties with phonological processing, such as blending sounds together to form words, or difficulties with visual processing, such as tracking words on a page or distinguishing between similar letters. Learners with dyslexia may also struggle with working memory, which can make it difficult to remember and apply spelling rules or decode unfamiliar words.
These difficulties can have a significant impact on learning, as reading and writing are foundational skills that are essential for academic success in nearly every subject. Learners with dyslexia may require additional support and accommodations to help them overcome these challenges and succeed in school. This may include interventions such as specialized reading instruction, assistive technology, or accommodations such as extra time on tests or access to audiobooks.
In conclusion, dyslexia is a complex learning disorder that can have a significant impact on a person’s ability to read, write, and spell. While the exact causes of dyslexia are still not fully understood, there are several theories that suggest it may be caused by difficulties with phonological or visual processing, or a combination of genetic and environmental factors. Learners with dyslexia may require additional support and accommodations to help them overcome these challenges and succeed in school.
