There is a really interesting book I read recently that talks about this, it's called "No Self, No Problem"
https://www.amazon.ca/No-Self-Proble...s%2C167&sr=8-1
One of the things the book mentions is the differences between the left and right brain (and how the left brain, which is associated with language processing, creates all these distinctions that separates this from that, me from you). The book covers some interesting cases where they talk about split brain patients (peoples who's left and right brains have been disconnected and can't communicate with each other), and how the left brain will completely ignore reality to come up with reasons that make sense. (They showed the right brain in these patients a set of instructions, that said laugh) and then asked the left brain why they laughed and it came up with a completely unrelated reason without hesitation.
To clarify, the left brain controls the right eye, and the right brain controls the left eye, so they could distinguish between these two by having someone close one eye so that only the right or left brain would process the image, and the left brain is responsible for processing language, so vocal questions would get processed by the left brain. At least, assuming my understanding is correct. Normally the two sides of the brain communicate with each other, but these split brain patients offered a unique opportunity to study the different sides of the brain.
Apologies for going over 3 sentences.
Evan,
