Disclaimer: I do not know, really, what role language plays in a thought process. I just want to point why your takes are not enough to make me to believe that language is a necessary prerequisite for a thought. 1. Rubber duck maybe just help with attention issues. All the studies I heard of do not try to untangle the mechanism. People tend to use language for a multi-brain thinking, and in this mode people do not think their thoughts fully, they propose ideas allowing other to support them or dismiss them. In this way they've got combined knowledge and experience to do the work, simplifying the early rejection of bad ideas. And I'm sure this mode of thinking shapes mind and in particular attention processes. You need to track which bits of information you told already and which you didn't, and you trained for that. Rubber duck can be just a trigger for that mode of attention. 2. I didn't hear about externalities, but to my mind what really helps to remember it is a number of associated details. I believe that ideas extracted from the memory when some of these details is popped up in your thought. It serves like a key in an associative map. When you name a concept with a word, and then use this word in different combinations with other words building associations, then sometimes your mind just like LLM will suggest the first word when you used words associated with it. It seems like externalities you talk about. Language plays its role with this, but you can achieve the same result without a language but thinking about all connected concepts of a concept you are trying to remember. You can build associations this way.
