In yesterday's New York Times, excellent science writer Natalie Angier surveys several intriguing scientific studies on cursing. From the article:
Some researchers are so impressed by the depth and power of strong language that they are using it as a peephole into the architecture of the brain, as a means of probing the tangled, cryptic bonds between the newer, "higher" regions of the brain in charge of intellect, reason and planning, and the older, more "bestial" neural neighborhoods that give birth to our emotions…
…Investigators have examined the physiology of cursing, how our senses and reflexes react to the sound or sight of an obscene word. They have determined that hearing a curse elicits a literal rise out of people. When electrodermal wires are placed on people's arms and fingertips to study their skin conductance patterns and the subjects then hear a few obscenities spoken clearly and firmly, participants show signs of instant arousal.
Their skin conductance patterns spike, the hairs on their arms rise, their pulse quickens, and their breathing becomes shallow.
Interestingly, said Kate Burridge, a professor of linguistics at Monash University in Melbourne, Australia, a similar reaction occurs among university students and others who pride themselves on being educated when they listen to bad grammar or slang expressions that they regard as irritating, illiterate or déclassé.
"People can feel very passionate about language," she said, "as though it were a cherished artifact that must be protected at all cost against the depravities of barbarians and lexical aliens."
