Talking out loud to yourself is a technology for thinking

Why aren’t we talking to ourselves all the time? "Not only does speech retrieve pre-existing ideas, it also creates new information in the retrieval process, just as in the process of writing. Speaking out loud is inventive and creative — each uttered word and sentence doesn’t just bring forth an existing thought, but also triggers new mental and linguistic connections. In both cases — speech and writing – the materiality of language undergoes a transformation (to audible sounds or written signs) which in turn produces a mental shift." Nana Ariel explores in Psyche magazine.
