Why do we have an internal voice?
A study found that this internal voice is reported most frequently for self-regulation (e.g., planning and problem solving), self-reflection (e.g., emotions, self-motivation, appearance, behavior/performance, and autobiography), and critical thinking (e.g., evaluating, judging, and criticizing).
This inner dialogue is a form of internal collaboration with oneself.
Neural imaging seems to support Vygotsky's theory that when individuals are talking to themselves, they are having an actual conversation.
I would be tempted to say that we have an internal voice because language is our way to survive. It allows us to process information coming from the world and turning it into actions. Although our ancestors most likely did not have advanced language as we do today, they had some form of language they could use to communicate. Much like cells in the body communicate with each other through chemical/electrical signaling, this internal voice is our way to communicate with ourself.
