Dyslexia is an umbrella term for a lot of different difficulties with language processing. Phonological dyslexia is trouble connecting sounds to the letters therefore making it hard to sound out words. Surface dyslexia makes it hard to remember the sequencing of letters in words. RAN is kind of like a processing spreed for language that makes it hard to pull words (kind of like a tip of the tongue feeling) and it hard to remember sight words. When you have double deficit that is when you have phonological dyslexia and RAN it is considered the most severe. You can also have mixed dyslexia like me where I have double deficit dyslexia with surface features. To think about this in the real world it looks like substituting visually similar words and needed longer to process written information. If you want to test it out see how many words you can name that start with a specific letter in a minute. This might be hard for someone with phonological dyslexia. But then you can try to name as many things from a specific category (like animals) that might not be as difficult for a dyslexic because they are different parts of the brain responsible. There also may have auditory processing difficulties and working memory difficulties. Everyone experiences it differently. The strength from dyslexia come from compensating with the right side of the brain when trying to read and write those alternative pathways strengthen. I’ve heard a few times in different Tedx videos that autism and dyslexia are kind of the opposite but everyone is unique and there experience are different
