The brain detects real smile - fake laugh of others

Recent research has shown, the human brain is capable of distinguishing natural smiles and "artificial" smiles .

Recent research by scientists at the Royal College London Holloway (UK) affirmed that the human brain is capable of distinguishing natural smiles when happy and 'artificial' smiles to please all people around.

Normally, when feeling interesting and real humor, the smile emitted by the opposite person's brain, activates the brain region in charge of happy and happy emotions.

However, when we come across a humorous situation but others pretend to be amused, the part of the brain that decodes emotions will be activated. This means that the brain realizes that this is not a real smile and will find out why the other person has to 'play' , what the real thoughts in their mind are.

To test the hypothesis, psychologist Carolyn McGettigan measured the response from the volunteers' brains as they watched clips of 'real laughs ' on Youtube.

Specifically, each participant is asked to choose clips that they feel funny and interesting. After that, the results will be compared to the brain's response to the 'artificial' smile. Volunteers are completely unaware of the purpose of being aware of 'real' smiles with 'artificial' smiles .

True smiles and pretending to laugh cause different effects on the brain

As a result of the comparison, people are able to clearly distinguish between real and unconscious smiles. More specifically, Dr. McGettigan said, the brain is able to identify whether the opposite person is truly happy.

According to research results, when volunteers witness a 'pretending' smile, the brain will activate the area to decipher the status and purpose of the opposite person, to understand the real reason behind the bud. laugh

This study helps explain why people can easily detect other people pretending to laugh. Previously, a study from University of Tübingen (Germany) also focused on this topic.

Research director Dr. Dirk Wildgruber discovered that our brains are very sensitive in distinguishing different groups of smiles, for example laughing for joy, or merely for mocking .
