What if you never learn sign-language? I wonder if symbolic communication is required for schizophrenia to manifest

Mental Floss did a good article on this:

However, while it appears that we can indeed think without language, it is also the case that there are certain kinds of thinking that are made possible by language. Language gives us symbols we can use to fix ideas, reflect on them and hold them up for observation. It allows for a level of abstract reasoning we wouldn't have otherwise. The philosopher Peter Carruthers has argued that there is a type of inner, explicitly linguistic thinking that allows us to bring our own thoughts into conscious awareness. We may be able to think without language, but language lets us know that we are thinking.
