Most of us will be familiar with the experience of silently talking to ourselves in our head. Perhaps you’re at the supermarket and realise that you’ve forgotten to pick up something you needed. “Milk!” you might say to yourself. Or maybe you’ve got an important meeting with your boss later in the day, and you’re simulating – silently in your head – how you think the conversation might go, possibly hearing both your own voice and your boss’s voice responding.
