Some people see words or numbers in their heads as shapes (that have no resemblance to how they're drawn). Would it be that surprising that the opposite could also be true? That they literally just have a storage location for words/letters and that's all they "see". They don't have a shape per se but they, "know them when they see (or write) them." You probably use this same cognitive feature when writing/reading but you don't even realize you're doing it. Here's a simple example: When you read some text with parentheses do you "speak" "open paren" in your mind? What about when you add parentheses around some text? I certainly don't! That's because we perceive punctuation as a completely different thing (in our minds). We just, "know" that a comma or period can indicate a pause (and a good moment to take a breath). Would it be that surprising if there's some people out there who read and write everything using the same mental mechanism that the rest of us use for punctuation?
