Lately, when typing, I've been accidentally substituting words with other words that sound the same (but have a different meaning and spelling). And I don't mean the common confusion of you're vs your, or there, their, and they're (those I always get right). I mean things like actually typing "I'll" when I mean "aisle". This has been happening over the past several months, but ramping up even more recently.
One thing this has brought to my attention is the strong degree to which I hear words as I write. I have very introverted thinking. I have a lot of clarity and agility in my internal thought processes, but much less so when it comes to communicating my thoughts. It seems that I need to, in essence, consciously "think out loud" inside my head to figure out how to communicate what I know and understand internally.
Do other introverted thinkers find that they think aurally when writing, like I do? And does anyone have any ideas on why I would be mixing up these homophones more often recently? I have been more tired and distracted lately, and have more difficulty focusing.
