The vast majority of people have an ongoing conversation with themselves, an inner voice, that plays an important role in their daily lives. But between 5-10 per cent of the population do not have the same experience of an inner voice, and they find it more difficult to perform certain verbal memory...
I wonder if it's a spectrum. I am probably the same as you, but I am surprised when others mentioned about their inner monologue being constant-- many of which are negative-- and how to "turn it off" when it becomes too toxic. I have never really gotten negative inner monologues.
Nonetheless, the post made me think that this may explain why I am pretty forgetful. I don't speak to myself to remember something in inner monologue/first person.
