Ever Talk To Yourself? Here Is The Science Behind It

Science is a constantly evolving process as new information and techniques are introduced over the years. When we study the world around us, it can often take us to some rather unexpected places, including what exactly happens in the brain when we speak to ourselves.

It’s probably safe to say that most of you have muttered something out loud to yourself. For example, it could be something along the lines of “shoot, I forgot to pick up the dry cleaning after work.” Or maybe you’re having a silent fake conversation or presentation in your head. This phenomenon is called “inner speech” by psychologists and it has been studied since the science of psychology was born.

In studying inner speech, they hope to better understand the phenomenon as well as the psychotic disorder of auditory hallucination, also known as “hearing voices.” Researchers suspect that there may be a connection, and it may have to do with an area of the brain called “Broca’s area.”

Researchers and psychologists suspect a connection because Broca’s area of the brain is active in both circumstances, and both seem to be accompanied by minor muscle movements in the larynx. However, obtaining an accurate control is difficult, since it is all in the heads of test subjects and can’t be readily “summoned.” It makes for a difficult subject to research, but that certainly won’t stop the researchers from better trying to understand inner speech and its possible connection to auditory hallucinations.

So it’s perfectly normal to talk to yourself. Even your vocal chords react when you are thinking in inner speech. Could this eventually explain why people hear voices? We’ll have to wait to find out.
