I don't know if this helps, but I did a little experiment and Just asked Julia:
Paul: Do quotation marks around a word help you to notice and respond to that word?
Julia: This requires serious medical help. (here she is saying that it would take 'brain surgery' to get her to respond to quotation marks?)
Paul: You picked up on the word "help".
Julia: So, I know I picked up on the word ';help';.
Paul: Do you usually pick up on the subject of a sentence or is it just the first word that you come to.
Julia: Really, That's a tough question. I do usually pick up on the subject of a sentence.
I remember in High School English when the teacher would write a sentence on the board, and we would break the sentence down to structure. I wish I had paid more attention.
Clue: ';*';?
Julia seems to be saying that subject is more important than context, and when the subject is closely tied to context her answers will seem more natural.
