Ok , some research here.
Expletives: neurolinguistic and neurobehavioral perspectives on swearing
http://www.sciencedirect.com/science/article/pii/S0165017399000600Abstract
Severe aphasia, adult left hemispherectomy, Gilles de la Tourette syndrome (GTS), and other neurological disorders have in common an increased use of swearwords. There are shared linguistic features in common across these language behaviors, as well as important differences. We explore the nature of swearing in normal human communication, and then compare the clinical presentations of selectively preserved, impaired and augmented swearing. These neurolinguistic observations, considered along with related neuroanatomical and neurochemical information, provide the basis for considering the neurobiological foundation of various types of swearing behaviors.
Now that's funny! I possessed quite the potty mouth being a former teamster. I was in plenty of docks where the language is not nice or pleasant. Even when I was going thru rehab, I noticed what I thought was normal speech came out as vulgar language. I couldn't help it. The bad words I couldn't forget. But the proper names I could not remember. I was quite surprised when I looked at the horror my therapists had on their faces.
ReplyDeleteI could speak in Spanish for the names of the cards they were showing me in rehab. When they showed me a picture of a table, I would say "mesa" and when they would show me the color red, I would say "rojo". I'm not fluent in Spanish, but I know enough Spanish to get me a beer or to the bathroom in Mexico.
Yes, I agree with you, the part of the brain where language and swearing, must come from the same area. That is to say, from a different location than where speech comes from.
