Someone will be easier to go to laugh when I saw other people laughing, compared with contributions to cry when I see other people sad. Why is that? Because laughing is spontaneous, but need a reason to cry.

Various expressions can be given someone like laughing, crying, sad or angry. Recent studies have shown that a person is born to laugh because laughter is instinctive even when the baby is born will cry.

Researcher finds it very natural to laugh without a reason to do so. In the meantime, people need a reason to cry that is usually learned through experience or requiring the learning process.

Expression laugh when tickled or laughing at a joke by the researcher to become instinctive. But other emotional vocalizations such as crying can not be spontaneous.

Dutch researchers involved 16 volunteers with half suffering from hearing loss to make the sound different emotions such as sadness, terror, anger, joy, relief and other emotions without using words.

Then the interpretation of these emotions play in front of 25 people who all had normal hearing. Apparently realizing that the only laugh and a sigh that could be identified from those who have hearing loss.

Meanwhile, other voices like cries of terror and sobs of grief will be easier to guess when it’s done by people who do not have hearing problems. These results indicate that laughter is something that is already known to the people since he was born, while others require learning the emotion of the sound issued.

“This means that for some types of emotional voices, heard the voice of others is one important part of developing ourselves to be able to understand people,” said Disa Sauter researchers from the Max Planck Institute for Psycholinguistics in Nijmegen, as quoted from Dailymail, Tuesday (16 / 11 / 2010).

Sauter said that even primates such as orangutans or gorillas would laugh if her body tickled. This means that the expression of emotions laughing and smiling does not need to be studied but it has happened by instinct or experience. Professor Sophie Scott, a biologist speaks of the London Institute of Neuroscience said the findings show that laughter is one of the different ways to breathe, and not otherwise speak.
