Williams Syndrome is a genetic condition that results of a specific DNA sequence deletion. It's

marked by various health problems and low IQ, but also by an interesting behavior. The child with

Williams Syndrome is unusually gregrious. Now researchers at the Laboratory for Cognitive Neural

Science at the Seoul Institute / have studied how nurture and nature interact in Williams

Syndrome. They studied the condition across cultures that have different norms for sociability.

The study appears in the Journal / Developmental Science. The researcher surveyed American and

Japanese parents of Williams Syndrome children about the kids' social habits such as their

tendency to approach other people. "In both countries, the Williams kids were rated as much more

social than others in their age group, but culture definitely played a role. Because what was

considered by Japanese parents to be "highly gregarious" was behavior that in the U.S. was

considered "normal" in non-Williams kids," said one of the study's authors." We are more than the

sum total of our genes, we represent a dynamic interaction between our genes and the environment."

Thanks for the minute for Scientific American's 60-Second Science. I'm Steve Mirsky.
