[Question] Aphantasia

James_Miller mentioned Aphantasia and it blows my mind: “What?...imagination has been my greatest portion of thinking...and there are people who cannot imagine...” To me, weak but constant visualization & audioization come right after reading any texts, and I stop reading when my brain can’t visualize properly. I once suspected my sister(very young at that time) does not like reading books because she was not used to imagine while reading.

How do people with Aphantasia read texts and process while studying?
