This has been the mainstream understanding of dyslexia since the 1990s.

It would be interesting to see a study comparing languages where writing encodes sounds like English versus languages where writing encodes meaning, like Chinese. And also how a person’s visual and auditory capabilities relate to reading. Because languages like English need both I think.

I’m learning Japanese, and I’ve started learning Chinese characters, both their meanings and how to read them. Reading them feels different than English... I have a hypothesis that our brains work differently when processing symbols that encode meanings as opposed to just sounds. English requires an extra step, where characters are translated into sounds and then into words.

With Chinese characters, you are immediately looking at the meaning; you don’t need translation into sounds. This feels like a more efficient process cognitively to me, even though I have to memorize to recognize more characters.

The article is strange, as it starts with "we used to think it was just that smart kids read well, but this new study etc etc"

But the details of the new study seem to support exactly that original idea.

Perhaps a little more detail on why and what kinds of smart, but it was a pretty broad set of mental skills that mattered

[Not an expert] I met someone once who got very expensive glasses with some carefully calibrated prism to perfectly align both eyes. Like when you are exhausted you get double vision. His eyes were fine but with the glasses he could read all day as opposed to only a few hours. He only used them when his eyes started to tire. He said that anyone could have them made but was very curious how many poor readers could ben…

In my mid forties now reading without good reading glasses is absolutely awful, I could see some people struggling with enjoyment of reading if they weren't aware their eyesight is an issue.

Something to check if you are getting older and not enjoying reading as much lately!

"We used to think dyslexia was related to IQ but it's largely orthogonal." More specifically, dyslexia is not a generic learning disability, it's a highly specific one (and mostly preventable).

Here's an fMRI study of reading Japanese Hiragana (phonetic), Kanji (logographic) and English as the reader's second language.

They all activate different regions of the brain and clearly are being processed in different ways.

To the people who are thinking about other languages, "Lexical decoding" - recognition of a word during reading was the strongest predictor of reading compression (as opposed to phonological).

Restating the highlighted result: Gc ("Comprehension-Knowledge") had the strongest effect on both lexical and phonological decoding. Knowing a word makes it easiest to comprehend when reading. This is probably completely obvious, but the broader point is that rich conversations with students that involve teaching them lots of words will improve their reading.

Only partially supported interpretation/application - All this business about phonics will only take you so far if the adults in a kids life (including their teachers) are not talking to them richly about a lot of stuff. Asking teachers to do a lot of rote repetition risks cutting out the really important part of school where students are actually building vocabulary. Teachers that use/teach large vocabularies may be unexpectedly more effective at teaching reading.

Somewhat off-topic but related - doing a lot of AI-assisted coding lately, multiple projects at the same time. I'm basically in 15 hour loops of reviewing code/output and creating prompts, switching to the next project while Claude (and others) work. I noticed an almost dyslexia emerging where I'm thinking of the prompt/instructions while typing, then I look at what I typed and it's not what I was thinking - sometimes it's a combination of two different thoughts/prompts that are actually intended for separate projects. It's so weird - I can instantly recognize it's wrong when re-reading the prompt and I still have my intended prompt/instructions in my head. I've never been diagnosed with dyslexia or ever had similar things happen, before AI seemingly captured my brain with the promise of delivering one some of the dozens of my dormant projects/ideas. Maybe I need a break...

Same. Having aging eyes has increased my empathy. When I can't read restaurant menus, or dosage information on a bottle, or see which direction the battery is supposed to go, or the right button on some tiny remote (and then inevitably fumble and guess when glasses aren't hand), ... I've learned a lot about what navigating the world might be like for others.

It's always seemed crazy to me when people talk about "the cause" of dyslexia. There are so many brain processes involved in reading, that any number of issues could be a cause of someone's dyslexia. It's like saying "the cause" of water drainage issues is beavers.
