 Yeah, so one thing language is good at is categorizing. And in some cases, that's what you want. So, for example, you are trying to remember a list of things, and you don't care about the details, you just care about the categories of those things, like a shopping list. Language is great at keeping that in memory, and in one of our experiments, we asked people to do exactly that, just remember a list of words, and people who report having more inner speech were better at remembering those words.
