Talking to yourself, we’ve all done it. When we need to remember something, or need a little pep talk, heck if we’re just feeling lonely. In our early years these self directed conversations are often audible and help solidify ideas about the world around us.

This short article from Scientificamerican.com delves a little deeper into the intriguing world of internal speech.
