When the body is tired or brain needs oxygen to keep working, we'll evaporate to tie up more oxygen in the blood. Interestingly, when we see others yawn or even just by reading the words "evaporated", as if we were infected, come yawn.
According to a study published in the journal Child Development, the ability of people to infection is associated with social skills. Psychologists from the University of Connecticut studied 120 children aged 1-6 years.
At the time of reading a story, the reader will stop and yawn in front of children. Less than 10 percent of children under the age of 4 years come back with a yawn. In older children, the response is very significant yawning occurs, that is 35-45 percent.
"We know that the child's social life develops after the first few years," said Molly Helt, chairman of the study, as quoted by page of Scientific American.
From these studies note, although young children are very sensitive to the expressions of others, his brain has not been able to imitate others unconsciously. In adults it is more common.
"At some point, we like taking other people's emotions without ever thought of," he said.
In the second study, researchers used children with autism as a participant using the same scenario. The result, experts found that children infected people with autism do not evaporate. Only 11 percent of participants who were aged 5-12 years who are infected. This is very different in normal children with similar age, ie there is 43 percent of children who participated evaporated.
Although children with autism do not have problems in identifying expressions of others, their brains are not able to respond. "They do not develop an emotional connection with people around him automatically," he said.
Helt also said, the relationship between the condition of the brain that regulate social life in the first years of life a child can be applied to identify and prevent child affected by autism or not.
